I am taking my own advice.
In that pandemic moment, there was plenty to learn from standing still.
The pandemic is an opportunity to review, rethink, rehash.
I have followed the development of Mycelium in Industry for the last few years and thought it would be good to stand back and review ………..

Construction Mycelium?

The Framework for my rehash comes from:

The EUROFUNG Consortium

The EUROFUNG network, founded in 1995, represents a European virtual centre expertise with globally recognised experts and long-term industry/academia collaborations in the field of white biotechnology. It has grown into a foundation with the aim to explore and enlarge the possibilities of filamentous fungi as cell factories.

Growing a circular economy with
fungal biotechnology: a white paper

the 2nd Think Tank meeting held by the EUROFUNG consortium  Oct. 2019


The term ‘biotechnology’ was coined by the Hungarian Karl Ereky in 1919, the same year that Pfizer became the first company to commercialise a product manufactured by the controlled fermentation of a mould. The product Pfizer made was citric acid for commercial use as a flavouring agent, acidifier and chelating agent in food, beverages, and the pharma and chemical industries. It was produced biotechnologically with the mould Aspergillus niger, and 100 years later, citric acid is still produced with this filamentous fungus and has formed a fast growing multibillion Euro market for convenience foods and beverages. Many organic acids, enzymes, life-saving antibiotics and drugs use filamentous fungi for production, and a lot of our foods and beverages would not exist at all without their fermentative capacities. No one disputes the fact that filamentous fungal-based biotechnology is of pivotal importance to our daily lives.  … … A 100 years after the birth of fungal biotechnology, this platform technology is undergoing a renaissance by providing sustainable solutions for diverse industries and markets. In the following, we will summarize current and anticipated products made from moulds and mushrooms and related new avenues of research. We will also highlight recommendations discussed during the EUROFUNG 2nd Think Tank consortium for ways to drive innovation in this renaissance through strategic and infrastructural measures for basic and applied science on filamentous fungi.

The lifestyle of filamentous fungi—moulds and mushrooms

The life of a filamentous fungus usually starts with a spore, which has a diameter of only a few microns (µm). The spore starts to swell in a humid and nutrient-rich environment and germinates. A germ tube forms that elongates to eventually form a thread-like, filamentous cell, called a hypha. After the hypha grows and elongates for some time, it forms a network of interconnected hyphal threads called a mycelium. When nutrients become limited in the substrate within which the mycelium lives, the mycelium starts to explore the air and space in order to form reproductive structures. …

… Filamentous fungi are both invisible and visible. The diameter of fungal hyphae range from 2 to 10 µm, and a fungal mycelium consists of a network of mm- to cm-long hypha. The mycelia of mushroom-forming fungi can colonise large surface areas, as illustrated by an individual of the honey mushroom Armillaria bulbosa (common name honey mushroom in English and Hallimasch in German) which has colonised > 1000 hectares of forest soil, making it the largest and oldest organism on Earth. Mycelia of mushroom-forming fungi can also be grown on various by-products and waste streams from forestry and agriculture. The efficiency of colonisation and biomass formation depends on the composition and physical properties of the substrate, the environmental growth conditions (temperature, humidity and pH) and the genetic make-up of the fungus. … … Notably, the predicted gene set for plant polysaccharide-degrading enzymes in these fungi is between 100 and 250, whereas only 30 appear in the baker’s yeast Saccharomyces cerevisiae. The success of S. cerevisiae, which cannot grow on plant polymeric substances, or the bacterium Escherichia coli as platform organisms to produce biofuel (ethanol), jet fuel (terpenoids), fine and commodity chemicals is only guaranteed by the filamentous fungal cell factories mentioned above that provide S. cerevisiae and E. coli with simple carbon sources during the fermentation process. Hence, filamentous fungal cell factories play a central role in the sustainable production of biofuels and chemicals.

LIGNIN History From Wikipedia
Lignin was first mentioned in 1813 by the Swiss botanist A. P. de Candolle, who described it as a fibrous, tasteless material, insoluble in water and alcohol but soluble in weak alkaline solutions, and which can be precipitated from solution using acid. He named the substance “lignine”, which is derived from the Latin word lignum, meaning wood. It is one of the most abundant organic polymers on Earth, exceeded only by cellulose. Lignin constitutes 30% of non-fossil organic carbon and 20 to 35% of the dry mass of wood. The Carboniferous Period (geology) was in part defined by the evolution of lignin.

Filamentous fungi and a wood-based bio-economy

Lignin is the most underutilised of all wood polymers due to its complex structure and difficulties in processing. It forms an amorphous network of phenyl propane units coupled to hemicellulose via ester linkages. It is the second most abundant natural material on Earth after cellulose. The worldwide production of lignin is approximately 100 million tons annually. One of the main challenges of lignin valorisation lies in its diverse structure and poor solubility. Most of the lignin obtained burns (Kraft lignin/black liquor) directly in the pulping plants to recover energy. Only about 2% of the technical lignin globally available (~ 5 million tons) is currently utilised. Basidiomycetes are unique in their vast abilities to modify and/or mineralise lignin, and these organisms should play a central role in developing the utility of this highly promising polyphenol. The potential of lignin as a material reservoir requires much more rigorous characterisation of the structure/function predictability achieved through these fungal transformations.

Hi Lesley,

In the Netherlands (especially in Zaandam where our studio is), we have a long history in wooden houses. As mycelium can be comparable to cork and wood, it’s possible, with or without coating, though to prevent it for the long term, a bio-coating is advisory (such as with wooden houses).

As Concerns Over Climate Change Rise, More Developers Turn To Wood … NYT

wood construction- Construction Mycelium - wait a minute Let's Think this Again

September 2020 – … Built by Katerra, a construction company based in Menlo Park, Calif., Catalyst is the newest of 384 large “mass timber” buildings in the United States. The first built in Montana in 2011, and according to industry figures, 500 more are under construction or planned. … … Katerra , founded in 2015, knew of only 10 large buildings in the United States constructed from cross-laminated timber panels. But demand for the products is so strong that the number of construction projects could double annually and reach more than 24,000 by 2034, according to a report released this year by the Forest Business Network, an industry trade group.

Wood Makes the Grade for High-Rise Construction

Wood construction components- Construction Mycelium - wait a minute Let's Think this Again

Recently the top-ranked architecture and engineering firm in the U.S., Chicago-based Skidmore, Owings & Merrill (SOM) and researchers from Oregon State University (OSU), launched a research project investigating the performance characteristics of a hybrid wood and concrete structural floor system that may offer owners, developers, architects and builders with a traditional flat plate construction alternative.

Why don’t we build more high-rises from wood? | RISE

wood high rise- Construction Mycelium - wait a minute Let's Think this Again

Alar Just, senior researcher at RISE who took part in the project and who is an expert on fire and fire resistance in timber structures, points out that the wood should mix preferably with other building materials to resist fire better and that the number of naked wooden surfaces should be as few as possible.

The pros and cons of building high rises with wood | The Star

2019- … “It is much more work,” Marc-André Roy, president of Sotramont, a Montreal-based developer, said in an interview. “We’re doing something new. It took more energy and man hours to get through everything … it’s more complicated.”
The wood used for Arbora is cross-laminated timber (CLT) a product made by gluing wood panels in an angled manner that provides stability and force. There are claims that panels are as strong as concrete but five times lighter, making them ideal for floors and load-bearing walls.

Filamentous fungi to mitigate plastic pollution

Current plasticizers become, among other things, additives to improve the workability of concrete, the construction material most used in the world. Plasticizers enable the use of less water by keeping the same viscosity of the concrete, thereby producing a highly workable material that hardens into a strong final product. Plasticizers are typically not covalently bound to the polymers, which, over time, may lead to environmental contamination via leaching. A bio-based alternative to the current fossil-based concrete plasticisers would be lignin functionalized to a higher solubility by the action of fungal or bacterial laccases or other oxidative enzymes. 

Filamentous fungi as biomaterials

Fungi thrive by decomposing and consuming dead plants by breaking down the plant’s cellulose, lignin and other sugars, then rearranging these molecules into their own biomass to grow. They secure their cell walls by chains of chitin and glucans, which, like cellulose and keratin, are naturally forming polymers found in the toughest of organic tissues. Chitin is the same ingredient that creates the durable and flexible exoskeletons of insects and shellfish. During the colonisation of substrates, hyphae bind the organic particles together, while degrading them simultaneously. The result is a composite material consisting of a bulk of organic substrate bound together by the hyphal network, by inactivating the fungus before the substrate degrades (e.g. by drying or by heat inactivation). Pure fungal materials come from complete degradation of the substrate or removing the fungal skin from the substrate. Both pure and composite mycelium find uses in different applications. …. …. Notably, mushroom-based materials can absorb and dissipate a variety of energetic forces, ranging from sounds to seismic waves to ballistics. They are naturally flame retardant, good thermal insulators and can be grown as flexible or rigid as one desires. While incredibly strong and durable, these materials will brake down into constituent minerals and dispersed easily back into the world. Materials grown through a process of fermentation and decomposition require far less energy, water and other resources than conventional manufacturing.

Mushrooms turn construction waste
into building blocks

August 2020 – The way Cleveland architect Christopher Maurer sees it there has to be a better way to dispose of construction and demolition (C&D) waste than just throwing it into a hole in the ground and his vision has led to a hook up with NASA and MIT.
Maurer, principal architect at Redhouse Studio is now working to scale up the Biocycler, a mobile technology which grinds construction waste and then processes it into blocks using mycelium fungi and calcite-producing microbes as the cement to bind it into a durable and formed material.
It’s one of three projects which are gaining traction for his team which includes a process to grow mushrooms in the poorest part of Namibia and an ambitious scheme to grow construction materials biologically “in a bag” on Mars for humans to later harvest and use.
The Biocycler, however, is the project concept closest to home since C&D waste and the perilous future of landfill sites are pressing problems across major North American cities.

Another important research project that Christopher Maurer is involved with from 2019… is Growing Myceliated Facades.

As mentioned in the EUROFUNG report:

The fungal kingdom is huge. There are estimates of a million species existing on Earth, of which we know of only a small proportion. Most are saprophytes and feed on dead plants and animals. Exploitations in biotechnology as cell factories have resulted with only a few dozen. Leveraging their metabolic capacities and flexibilities will be key to achieving the circular economy…

Growing Myceliated Facades

Manufacturing and exposing experimental panels in a facade setting  May 2020 – …The research presented in this paper focuses on two aspects: finding a way to produce large myceliated panels outside of a microbiology laboratory and testing the outdoor durability of these panels in an outdoor façade setting. For the first part, we experimented with three aspects: substrate mixes, sterilization/pasteurization method and growth environment. For the manufacturing process, we tested different substrate combinations for the speed of mycelial growth. We introduced Structural elements in some panels to enhance their structural properties. We conducted experimentations on shape variations to further broaden the potential building applications. For the second part, we compared four post-growth treatments: raw, compression, baking, and a combination of compression and baking. Finally, we exposed the different panels to the outdoor environment to assess the panels’ durability. …


For the myceliated panels production, we made the optimal combination of red oak saw dust with soy hull and gypsum, pasteurized and grown in tents allowing air exchange. This combination was the last one tested in this process and considered for further research. The fungus fully covered the panels’ surface after 3 weeks, but the inside was lacking growth. Once the panel’s surface was fell, structural integrity was reduced. Unbaked compressed panels were best at maintaining their original morphology in the outdoor setting. Keeping the fungus alive allowed it to continue its growth on the prototype, which seemed to improve structural capacity of the panels. Yet, for indoor usage, the alive fungus might damage the building and create allergy problems. Therefore, in most building applications, it is important to bake the myceliated panels.

While implementing growth in future architecture, the processes need further development. Manufacturing myceliated panels for buildings are an example of using biological organisms for the material production stage of a building life cycle. Even if this material is biodegradable, today’s manufacturing process still requires the use of unsustainable materials. The longevity of a myceliated panel in an outdoor environment is far from the expected lifespan of a building, but its deterioration could potentially be part of the growing media of a green wall system. We will conduct further research growing other fungus species on diverse substrate sizes and densities, and the growth of plants on the myceliated panels.

Concluding remarks

We would not be able to live the life we are living without the help of moulds and mushrooms from nature. Fungi are [our past, ] our present and they will shape our future. They are champions in recycling and material transformation; their biosynthetic capacities is unique in the microbial world. We should do our best to harness their abilities! Fundamental and applied science on fungi offers solutions for the shift from our current petroleum-based economy into a bio-based circular economy, opens new avenues for food security as demand increases from a growing human population, and provides us with new concepts on how to ensure human, animal and plant health in the future. Science on fungi discussed in this white paper already contributes to 10 out of 17 UN development goals (Fig. 8) and their role will become even more important for the future of mankind.

The economist Peter Drucker (1909–2005) once said: “The best way to predict your future is to create it.” Stronger mutual collaborations between scientists, engineers, artists, designers and industrial stakeholders, and vivid communication with the general public and policymakers will ensure that the inter- and transdisciplinary science on fungi will create a path towards innovative breakthroughs. As Peter Drucker suggests, this will create a sustainable economic future based on fungal cell factories for years to come.

Why future homes could be made of living fungus 

You might be wondering what happened to Hy-Fi, that igloo-like structure in New York. The answer points to one of the most beautiful things about mycelium buildings. No wrecking ball or slow decay for them. It was taken down and composted. 

This mushroom monument gave architectural researcher Phil Ayres an idea. ‘It was impressive,’ said Ayres, who is based at the Centre for Information Technology and Architecture in Copenhagen, Denmark. But this project and others like it were using fungus as a component in buildings such as bricks without necessarily thinking about what new types of building we could make from fungi.  
That’s why he and three colleagues have begun the FUNGAR project – to explore what kinds of new buildings we might construct out of mushrooms. 
Buildings and construction are responsible for 39% of anthropogenic carbon dioxide emissions – and a whopping 21% of those emissions come just from the making of steel and concrete. Construction also uses vast amounts of natural resources. Take sand, one of the principal ingredients in concrete. It takes a special sort, with just the right roughness, to make concrete. These days it is a lucrative commodity and controlled in some parts of the world by sand mafias and stolen by the boatload from islands.  …
… The next major goal for the FUNGAR project is to build a small, freestanding building. They plan to pull that off within a year and then spend time monitoring it as it ages. It is crucial, says Ayres, to be able to monitor the living structure and see how it changes. It isn’t yet clear exactly what sorts of structures might end up being made from fungi, but they will probably start small. 

Construction with Mycelium- Construction Mycelium - wait a minute Let's Think this Again
Fungar, the project that that seeks to develop a fully integrated structural and computational living substrate using fungal mycelium for the purpose of growing architecture. Fungar will target two principle technological breakthroughs:
1. growing monolithic structures at metre length scales
2. functionilising the mycelium network to act as a computing device
