Dr. James Trappe has written that he does not believe I have grown anything, just enhanced already existing production. Yet for 10 years after seeing increased production at Paul Bishop’s tree farm, Dr. Trappe did not attend multi-annual forages held there. Thus he could not verify a friend of mine, who attended such a forage, and found 3 pounds of truffles within 2 hours. My friend is now deceased: pancreatic cancer. But for the last 4 months of his life, he could have fresh Tuber gibbosum and Tuber oregonense anytime he wanted.

It’s odd: grow a poisonous mushroom, like Paxillus involutus, and not many people deny cultivation occurred. That was one of the first mushrooms I grew, btw. Grow Cantharellus formosus or Tuber species in the same manner, and lots of people, including someone Trappe named as a truffle expert, are certain I haven’t grown anything. I remember bringing in a 7-inch across the cap Lentinula edodes I had grown on a 1.5" diameter limb at my parents’ farm to an OMS fall show. Dr. Lorelei Norvell insisted the fungus could not possibly be Lentinula edodes, as it was just too big. I suggested she look at the saw-toothed gills. She then accepted Lentinula edodes, but still did not accept I cultivated it. I guess it grew wild accidentally on the same branch I was trying to grow it on.

One thing I’m certain of: mushrooms are much easier to cultivate than many experts think. Too bad more experts don’t try to cultivate a variety of fungi. Even the failures at cultivation, like my attempt to grow Tricholoma magnivelare, reveal more about how cultivation might work in the future.

I’ve tried growing Leucangium carthusiana 3 times, but only got fruitings twice. So I consider that 66% successful. It isn’t as good as it could be, but it’s better than anyone else I’ve heard of trying to grow it.

I’ve done better with Tuber gibbosum: 4 attempts, 4 successes. A major point for whether cultivation occurs or not is whether the technique is successful multiple times. I have voucher herbarium collections from each of those inoculation sites.

Sorry to drone on. This does beg the question: what is cultivation? If you plant a seed in a garden, and later see a plant related to the seed you planted growing where you planted it, I call that cultivation. If I substitute known fungi under the same conditions, I call that cultivation too. It helps, though, to know whether the fungus you are trying to grow has actually already been found on the site. Or, more importantly, not been found on the site. It takes a little longer in terms of time, but is more suggestive. Better than proving cultivation by mycorrhiza, but without a sporocarp to back you up. Did you know that Tuber melanosporum forms mycorrhizae with grapes, but never fruits with grapes?

been successful at a very primitive method with princes(A.augustus) under spruce and doug fir at my parents house on the ocean using stem butts and corrugated cardboard. I remember reading from Stamets that Frank Herbert was successful in cultivating the stubborn chanterelle by placing somewhat rotten(past their prime) specimens in a tub of water with salt and sugar and then would pour that mixture in his yard. Apparently this method worked…. But, to answer your question I have definitely transplanted rhyzomorphic stem butts of fresh A.augustus to be placed between soaked piece of corrugated cardboard and then transpanted that beneath the two neighboring trees mentioned 5 inches beneath the dirt. This current summer season there is a wonderful flush of princes. I know A.uagustus accumulates metals such as cadmium and others so I am more hesitant than ever to consume them(although just smelling them is enough for me!) All G.oregonense/G.tsugae I have ever removed has pulled off easily(I only pick them relatively fresh-while leading white growth edge is still present. Never harvest a Reishi after it has lost its spore layer(usually dark purple/and dull at that point). Again I must say that your growth of Hypogeus fungi is staggering to say the least- I have never heard of anyone(at least in the US) that has had success with truffles… Save for maybe Trappe… You’re amazing!

Gilbertson and Ryvarden described several Ganoderma, but also noted the spore shape and size were not conclusive to use by themselves. Substrate was suggested as a better indicator, but I am not certain of that, either.

G. oregonense pores are supposed to bruise brown when fresh. But so does almost any Ganoderma. G. applanatum reaches massive size locally when grown on old-growth Black cottonwood, with specimens 20 or more inches across and relatively dull cap surface for a Ganoderma. But they make wonderful panoramic pictures!

G. lucidum may start out reddish- to burgundy-colored. Under high CO2 conditions, it forms what is called an antler-shaped sporocarp: highly prized in Chinese pharmacopeae. I do not find that form here, even when our local Ganodermas are grown specifically in high CO2 conditions (i.e. left in space bags). And at least some people have called Ganoderma tsugae and others “Laminated Root Rot”, why would anyone intentionally grow them on conifers? (I like growing trees too much, perhaps.)

G. oregonense may require an axe or hatchet to remove a sporocarp from the log, even though the flesh is said to be relatively soft when young. I guess I must find mostly old sporocarps, then.

Have you been successful at growing A. augustus? I haven’t tried most Agaricus species. They seem too difficult for me.

But I have done Laccaria, Morchella, Leucangium, Geopora, Tuber, Hymenogaster, Rhizopogon, Barssia, Endogone, Boletus, Suillus, and others. And of course, Hericium. A class-mate of mine from Lebanon has been growing them commercially, and gets them to fruit in space bags, usually within 28 days from the initial inoculation. VERY fast growing and terrifically easy! Suitable for the simplest cultivation techniques. Found one specimen growing on a wounded Bigleaf maple (Acer macrophyllum) near the Portland Rose Test Gardens a few years ago. Big. Too big to eat when I found it, but easily 10 pounds or more.

Ya- Chris Bailey(who distributes to Solaray and few other companies) contacted me to send him fresh specimens of G. oregonense last summer(which I collected from deep in the northern coastal forests of the Olympic Peninsula on Western hemlock to be cloned. I have also personally sliced and dried pounds of G.oregonense and G.tsugae and used in pills and teas for last 2 years. One friend of mine was diagnosed with fibromyalgia and skin cancer and took G.oregonense tea along with G.lucidum pills. in 2 months Fibro completely went away-as did the cancer. Not claiming it was only the Ganoderma responsible for her miraculous cure- but am positive they were a contributing factor. By the way, another good resource is the 2004 article on Ganoderma phyologenesis from Hong and (Tsung et al2004). I am totally impressed with the work you have done with truffles and am blown away that you even attempted cultivating matsutake! I have had some success with boletes(transferring stem butts) along with the easily transferrable P.cyanescens and A.augustus. Love to hear your passion and results using Hericium. I have brought home some 3 foot long beauties of H.abietis from near Quinalt that have no doubt that they contributed to my both mental and physical health. I absolutely love to know there are others out there that not only hunt/identify fungi but actually use and trust it as a live saver :) I am glad you are feeling good and having optimal health currently. I currently take Stamets 7 once a day in conjunction with B vitamins and Ginseng. Thanks for all your advice/ wisdom kind sir :)

Fungally,

Drew

Tried growing G. tsugae in WA on Red alder. It never took. Also grew it on recent Tsuga heterophylla stumps, and it grew rapidly without problem. Found on the same property growing abundantly on downed hemlock, but also on many hemlock stumps: one of the reasons I was drawn to the property for mushroom cultivation potential.

Tried growing Tricholoma magnivelare there. No results after 15 years. Win some, lose some. Grew Lentinula edodes, Auricularia platyphylla, Tuber gibbosum, Tuber californicum, plus expanded existing production of Leucangium carthusianum there.

Happy to hear from another cultivator!

I thought Paul Stamets and I were almost the only people growing Ganoderma. Good to hear others have an interest in the medicinal aspects of fungi.

I developed a strong interest after developing symptoms of MS (multiple sclerosis), but never went for a diagnosis. My leg would go completely numb while I was walking. I would be walking along fine, then find myself on the floor, with no warning. Leg would be completely numb. I could pinch it and not feel it. Would last progressively longer and longer. Got so bad I was nervous crossing a street. Couldn’t guaranteee I’d get to the other side. I then had a single serving of Hericium erinaceus, which was one of the first fungi I felt comfortable in identifying in hand with a book. Had it with pork fried rice. No more MS symptoms. That was 22 years ago.

If interested Gilbertson R & Ryvarden L. 1986. North American Polypores: Vol. I & II. FungiFlora, Oslo, Norway. Have a signed copy of Christopher Hobbs book, after he was invited to speak at Oregon Mycological Society while I was president there. Some fascinating insight into fungi and mycology in his book.

However, G.oregonense fruits on Tsuga heterophylla as well. I initially thought most stemmed Western Reishi species were all G.tsugae when I began my obsession with medicinal fungi 5 years ago. It has been a long journey- still these two species are always under great debate as to exclusivity and taxonomy. I have a few species being cloned by a couple US companies currently and they may all turn out to genetically be Ganoderma tsugae… Not exclusively G.oregonense. I have even collected Small species of varnished Ganoderma here in WA that were fruiting on hardwoods( indicating G.lucidum, or G. resinaceum based on substrate) but most all references claim G.lucidum DOES NOT FRUIT HERE.
Ganoderma are my favorite and most respected species- I love and have gained many staggering results from their medicinal value. For more insight into Reishi spp. read “Reishi mushroom” by Terry Willard, or “Medicinal Mushrooms” by Christopher Hobbs.

As always, I appreciate your input and help Daniel :)

substrate more indicative. Ganoderma tsugae is by definition on Tsuga heterophylla.
