A HEALTHY, SAFE, POSITIVE COMMUNITY THAT IS SELF SUFFICIENT NOW AND FOR FUTURE GENERATIONS
Mushroom Cultivation
Skeena Watershed, Willoughby Arevalo, and Sik-E-Dakh Band partnered up to do this course about how mushrooms can be cultivated and used for food security, remediation and medicinal use.
Mushroom Cultivation Course
Our presenter Willoughby Arevalo is a mycologist, artist, kitchen wizard and educator who made friends with mushrooms as a young child and has been showing people how to work with fungi for the last decade. Willoughby regularly teaches community workshops locally and internationally on mushroom cultivation, ecology, identification, foraging, and cooking. Willoughby serves on the Education Committee of the Vancouver Mycological Society. He works on an organic vegetable farm, makes art in relation with fungi, and grows mushrooms at his home in Vancouver, BC.
Saturday
Saturday was a great start for the class. Willoughby walked the class through the mushroom life cycle. Mushroom life needs, overview of cultivation process, and cultivation principles.
​​
-
Feeding expansions, riding the mycelial wave
-
Sanitation and the pure culture paradox, define sanitation vs sterilization vs pasteurization
-
Advantages and paradigm shift of airport lid technique and open-air liquid culture
-
Planning cultivation scope and scale-appropriate technologies; workspaces, tools, and equipment
-
We discussed culture sources: cloning from wild and cultivate, to purchasing. Willoughby walked the class through the preparation of liquid culture and agar media. He did a tissue culturing wild mushroom to a liquid culture and agar demonstration.
-
The group got to do a Liquid Culture to Liquid Culture transfer, tissue culturing to liquid culture and agar(in open air/sacrificial for agar)
-
We discussed incubation/aeration, culture maintenance and storage.
-
Willoughby did a demo doing a low tech culturing methods: spore slurry, carboard stem-butt spawn.
-
Grain spawn. Talked about why and how. Demoed a small batch of grain preparation ( non sterilized/sacrificial). Held a hands on demo with transferring liquid culture to grain transfer.
-
Went for a walk where we focused on TEK, edibles, medicinals and remediation allies; fungal relations with plants and animals. Collected a few mushrooms to culture (with Sik-E-Dakh consent and permission)

Sunday
​
Sunday was a great second day. The whole group got to reflect on yesterdays activities. Touch base about the plan for the day. We started talking about fruiting substances/outdoor spawn substrate formulation, preparation and inoculation.
​
-
Discussed containers, substrates (what's locally abundant), sterilization, pasteurization, and alternatives.
-
Sawdust hydration demo was done. The group got to pass around a sample of hydrated sawdust to squeeze and feel. Also did hands on practice with sawdust inoculation with bag closure options as well incubation.
-
Fruiting principles: humidity, air exchange, light, temperature, sanitation; harvest timing, post harvest storage, preparation and preservations; (not) sharing the harvest ("pests")
-
Talked about fruiting spaces: Humidity tent, mini greenhouse, fruiting room; as well as a passive outdoor options for humidification, ventilation and light.
-
Growing with the seasons to minimize temperature control
-
For the afternoon we went outside. Did a lot more hands on work for the second half of the day. We got into log inoculations, mushroom bed basics. This is where we went into mycoremediation principles;
-
Chemical degradation through fungal digestion (esp. hydrocarbons)
-
Heavy metal translocation and uptake
-
Filtration of biological (bacterial) contaminants and potentially other contaminants
-
Cold fire, soil building
-
Integration with other bioremediation (Phyto, bacterial, worms.....)
-
We go to inherent challenges & solutions of mycoremediation:
-
Relatively new practice, more lab research than real-world applications- thoroughly review literature
-
Novel substrates- creative/informed choosing of species alliances, assisted adaptions/strain development in lab
-
Wild world factors- weather, competitors, animals, etc.
-
Scale and scope of contamination- need lots of spawn, people power and funding
-
Human health and safety during the work that you are doing
-
Testing- lab testing of samples, bioassays
-
A student lead a brief discussion on Creosote rail ties.
Types of Mushrooms the Class Encountered
​
-Amanita muscaria/Fly Agaric, orange, red or yellow with white warts on cap, toxic and psychoactive, rich in folklore
-Hebeloma/poisonpie, smells like radish, collects nitrogen from dead animals for their tree partners.
-Mycena haematopus/Bleeding Fairy Bonnet, beautiful tiny wine coloured mushrooms on wood. Stalk bleeds when squeezed. Toxic. Some mycenas are bioluminescent.
-Chondrostereum purpureum/Silver Leaf Fungus, thin purple parchment bracket, parasitic on deciduous trees, used in forestry to prevent stumps from sprouting.
-Lycoperdon sp./Puffballs, edible when white inside, styptic when dry. Associated with the cosmos in many FN cultures.
-Honey Mushrooms/Armillaria, tree parasite that grows huge networks of reddish black rhizomorphs (mycelial cords) which are bioluminescent, edible when cooked, highly variable in appearance, possible ally against creosote rail ties. Clustered to scattered growth on or near wood, white spore print, stalk with tougher, darker rind and pale, pithy inside. Veil when young, often disappearing.
-Fried Chicken Mushroom/Lyophyllum decastes, big clusters on ground (not on wood) with greasy feeling brown-grey caps, white stalks, pale gills. Mild taste, edible. Related to cultivated shimeji mushrooms of Asia. We did spore slurry with them.
-Granny’s Nightcap/Cortinarius caperatus , distinctively wrinkled orange brown cap, atop cream coloured stalk with a membranous ring. Edible
-Russula-like Waxy Cap/Hygrophorus russula or R. erubescens, beautiful pinkish reddish, slimy, edible but not excellent
-Chaga/Inonotus obliquus, very slow growing parasite on birch. Simmered tea is antioxidant and anti cancer but also high in oxalates. Overharvested in some areas. Can be rebrewed many times.
-Phellinus tremulae/Aspen Conk, heat rotter of live aspens, good for carrying fire
-Turkey Tail/Trametes versicolor, anticancer, immune modulating. Enzymes capable of degrading many toxic chemicals. Performed best in local creosote trials. Grows on most wood types, extremely common worldwide.
-Cortinarius/webcaps, common genus of mycorrhizal filled mushrooms with rusty spores and cobwebby veil. Over a thousand species, only C. caperatus is worth eating. Includes many toxic species including some deadly ones. Red and orange gilled species (section dermocybe) give excellent fluorescent red and orange dyes, historically used by Coast Salish on wool in blankets etc.
-Aureoboletus (Boletus) mirabilis/Admirable Bolete, choice edible with velvety dark brown cap, club shaped brown stalk streaked or marbled with yellow and red, pores yellow to olive green. Associates with Hemlock and rotten wood. Lemony flavour. Often accompanied by Wooly Pine Spike.
-Catathelasma imperialis or evanescens/Imperial Cat/Cat’s Paw/Black Pine etc, a look alike to matsutake but harderflesh, grey cap, decurrent gills and smells like grain and/or cucumber. Edible. Often huge with deeply rooting stalk. Mycorrhizal with conifers
-Birch Boletes/Aspen Boletes/Scaber Stalks/Leccinums, multiple species all with dark scabers on stalk. Edible but just okay, though orange capped species have caused a number of poisonings. Probably safe for most people when cooked for a long time.
-Strap Club / Clavariadelphus ligula, grows in troops in woods, resembling Cordyceps but without the bumps on the upper part. Beige. The larger and oranger C. truncatus/Flat Topped Candy Club is super sweet tasting and makes an excellent dessert.
-Russulas /Brittlegills, easy to recognize as a genus, hard to ID to species. Most edible species are mild tasting when raw; most toxic ones taste spicy/acrid. Commonand important mycorrhizals. Lactarius/Milk Caps are similar but give milk when cut or broken.
-Hericium cirrhatum/Tiered Tooth Fungus, extremely rare relative of Lions Mane. Red listed in Europe. This one is the first recorded occurrence I can find in BC. Only 8 observations of it in Canada posted online, most in Alberta, all on aspen. We cloned it. High food and medicinal value. Induces nerve growth factor. Could be used for habitat protection where found, say if found in a pipeline route. Might be easy to inoculate into standing dead aspens or to inoculate and girdle live trees.
-Purple Fairy Clubs/Alloclavaria purpurea, grows in large groups, sometimes in fairy rings. So cute edible but tiny and watery.
-Western Matsutake/Pine Mushroom, fragrant choice edible prized in Japan and exported en masse. Commercially harvested locally. Mostly grown under moss. Mycorrhizal with pines, hemlocks, Doug firs, oaks. Spicy, musky smell.
-Indigenous Paint Fungus/Echinodontium tinctorium, traditional source of red paint, trade good. Also gives orange dye. Grows on branch stubs of healthy or dead Hemlock and other conifers. A conk with teeth. Interior flesh is brightly coloured but exterior is grey to brown to black.
-Sprit Gummy Bear/Jelly Tooth/Cat’s Tongue/Pseudohydnum gelatinosum, translucent whitish, small , shaped like an oyster mushroom but with teeth instead of gills. Grows on downed wood from twigs to logs. Edible, even raw, like forest floor flavoured gummy bears. Pleasant texture, mild flavour, refreshing. This and other jelly fungi, like Witch’s Butter, Orange Jelly etc, used by Quw'utsun as a refresher in the days before water bottles, called Shmut’kw in Hul’quimi’num (from Luschiim’s Plants, book by Luschiim Arvid Charlie and Nancy Turner). Jelly fungi also used in Traditional Chinese medicine for cooling and drying actions. Soothing to mucus membranes.
-Artist Conk/Ganoderma applanatum group, perennial conks with white pore surface that stains brown upon contact. Can grow for decades in some cases. Medicinal, with similar properties to their cousin Reishi.
