River City Mushrooms Cultivating mycological literacy in Treaty 1 - Winnipeg, MB and beyond. Programs, workshops, grow kits, spawn and more 🍄 Join our mailing list 📬

An online repository of educational articles and experiments illustrating how to foraging for and cultivate edible & medicinal plants and fungi. The premise of this knowledge is to outline ways in which we can use both plants and fungi as a conduit for creating ecologically sound and interconnected food generating communities on a local and global level that will remain sustainable and resilient well into the future.

We’re back at it today with another species highlight. I’ve been growing this one for a couple of years now, and it’s definitely got a bit of a trick to it. Pioppino (Agrocybe / Cyclocybe aegerita) is a really tasty and unique culinary mushroom that is not nearly as popular as it should be.

Although the yields are lower than with oyster (Pleurotus spp.) or lion’s mane (Hericium spp.) mushrooms, pioppino have a really nice nutty and earthy flavour that becomes richer and deeply savoury when braised in sauces and stews.

I often cook the stems and the caps of the mushrooms separately, since they have different textures. The caps are fairly delicate and so I like to gently simmer them in oil or butter with minced garlic and serve over pasta or on top of generously buttered toast.

The stems have a slightly more fibrous and structured texture. These are the sections that I cut or slice and cook as part of a saucy stir fry with vegetables, or add directly to the pasta noodles since these sections can survive being tossed around, getting coated in sauce and not fall apart.

Pioppino mushrooms are a wood loving species, but they cannot be cultivated as a perennial in Manitoba. In the wild, this species grows out of the stumps and rotting roots of poplar trees throughout the south eastern United States and parts of central and southern Europe.

Pioppino can be cultivated in a number of different ways. Grow kits work very well indoors, and are perhaps even easier to care for than the more popular oyster and lion’s mane mushrooms. Pioppino can also be grown outdoors by shallowly burying the grow kit in the soil.

So long as the location is shaded, protected from strong winds and watered regularly, you can expect a flush of pioppino mushrooms to grow directly out of the soil within a few days of being planted and watered. Pioppino are a real winner in my books. You should give them a try.

I think it’s about time for another species spotlight. Hericium erinaceus, better known as lions mane, is a delicious, distinctive and iconic gourmet edible mushroom that is also a medicinal and nutritional powerhouse.

Like oyster (Pleurotus spp.) mushrooms, lion’s mane is a wood decomposing species that thrives under both indoor and outdoor cultivation. Lion’s mane mushrooms grow as a collection of firm masses covered in delicate ‘spines’.

The texture of the mushroom is somewhere between a combination of crab and chicken breast with a mild and only slightly ‘mushroom-y’ flavour. Lion’s mane lends itself well to being marinated, seasoned or drenched in sauce.

Lion’s mane is consistently the most productive mushroom that I grow, even outpacing white and blue oyster mushrooms, which are already known for producing excellent yields. They’re a beautiful mushroom and very easy to grow.

Mushrooms can be cut into slices, dredged in egg, flour and panko before being shallow fried like a schnitzel or chicken cutlet; minced finely and browned in a pan to be added to rice or quinoa as a side dish, or absolutely anything in between.

Lion’s mane has a long shelf life once picked and a remarkably versatile culinary repertoire. This mushroom, like many others; is a perfect protein, rich in minerals, B complex vitamins and many other essential micronutrients.

If you haven’t yet tried this wonder of the gourmet mushroom world, I encourage you to come out snd give them a shot. I’ll have lion’s mane available each week on Tuesdays and Wednesdays this summer.

Hey folks! Liquid culture re-stock just went live on the website. White oyster, blue oyster, lion’s mane and pioppino are now available, with more to come soon. I can ship these nation-wide, so if you’re interested and live out of province, let’s chat✌️🍄‍🟫🪄

After 4 years, I have decided to bring back pink oysters (Pleurotus djamor) for the summer. These are a striking species of oyster mushroom of tropical origin that thrives in high humidity and hot weather, where it grows quickly and produces hearty flushes of bright pink mushrooms. 🩷

Since this is a species that originates in warm climates, temperatures below 10°C can be detrimental to their development. So for outdoor growing, the best time to grow your pink oysters is from mid June through to late August when we can expect the warmest possible conditions. ☀️

You can grab a pink oyster grow kit from me on Tuesdays at or on Wednesdays starting the first or second week of July. I’ll probably grow some fresh for these markets as well - so keep an eye on this space if you’re interested 👀

I’ll be sure to let you all know when I expect to have the first round of pink oyster grow kits available, and when I have a fresh crop coming down the pipes. Grain and sawdust spawn for this, and all the species and varieties I produce, are also available online. Always made fresh to order ✌️💖🍄‍🟫

Hey folks! I’m very pleased to announce that I will be hosting a mushroom log inoculation program @ The Forks on Monday May 5th! Visit the RCM website for details, or check out the link in our bio to read up on more details for the event and register! 🪵

This is one of the more popular requests that I get for programming, and although getting access to logs that are cut at the right time and in the right condition can be tricky, the stars have successfully aligned this year to make it happen! ⭐️

There are 3 ticket tiers available for this program, based on whether or not you would like to just come and learn ($30), inoculate your own log to bring home and grow ($50) or come along with a partner / friend and take home a log to grow together! ($80) 🤝

This program is limited to 30 spots, so if you’re game to try growing your own mushrooms in logs this year, don’t delay! We’re likely to sell out quickly. My newsletter went out yesterday morning, and we are already just under 1/3 full! 😧

Drop a comment below if you have any questions about the program! The willow logs that we will be using this year have been generously supplied by Paul Krus whos wind row willows needed some thinning this year 🪚

A question that I sometimes get is ‘what happens to the grow kit after it is finished producing mushrooms?’, and I’m glad to tell you that there is a very good and satisfying answer to that.

Our grow kits are produced using entirely natural materials. Our blends contain nothing more than hardwood sawdust, wheat bran, soybean hulls, oat grains, and of course mycelium.

These blocks shrink considerably over their life space and hard days producing beautiful, delicious mushrooms, sometimes by as much as 1/3. Most of this is loss of moisture.

This leftover material, still rich with living mycelium, is a gardener’s delight. This substrate is rich in carbon from the sawdust as well as additional accumulated and manufactured nutrients from the mycelium.

Spent blocks can be removed from their bags, then broken up and shredded before being added directly to a compost pile or worked directly into the soil. There, they can continue to work their mushroom magic.

Both the mycelium and sawdust components, as they decompose, enrich the soil while also improving the workability, moisture holding capacity and porosity of your soil. It’s fantastic for loosening up heavy clay.

So, never throw away your spent grow kits! If you have access to a garden space, recycle them back into the earth from which they came. There, they will help to return all the carbon they contain back into the ground, where it belongs.

Happy spring equinox! Figured this would be as good of a time as any to introduce the newest member of our grow kit line up! Available online now and at markets throughout the summer months! 🌻

Our Manitoba enoki (Flammulina velutipes) is a high yielding and reliable producer that is directly cloned from a wild specimen found growing in the West End neighbourhood of Winnipeg. 🏡

This species has a definitive preference for growing from dead elm trees, but has proven adaptive enough to flourish when growing from our supplemented sawdust substrate that is a feature of all our grow kits. 💪

This strain grows as a dense cluster of small, bright yellow and orange mushrooms with a sweet, mild flavour and a snappy, almost noodle-like texture that is most at home in light, brothy soups like miso and ramen! 🍜

The cluster forming habit facilitates an easy harvest that is also mess free! Trim mushrooms by an inch or so from the base once harvested, leaving the long, flexible stems intact! 🍄‍🟫

Try it out and let us know what you think! We plan to grow out these beautiful enoki mushrooms fresh as well, so be on the lookout for it this summer when we get back into outdoor farmers market season! 🥕
