So, we found this chanterelle in the woods today. I said to my students, “oh it looks like it has a parasite. I’ll bet that it is a pyrenomycete asco or maybe a mold like Cladosporium.”
However, when we got back to the lab, I scraped a bit of the black, and it came off very easily. hmmm. I mounted it in some 3% KOH and found clamps on the hyphae and spiny spores. Well. I thought, I should have cleaned off the razor blade better. that’s not an ascomycete. So I got a new razor blade and made a second scrape. Again the same thing. It’s a Tomentella! Tomentella is a mycorrhizal fungus in the Thelephoraceae that forms a resupinate (flat) fruiting body. They are very common, but not collected by most people. The black part on the stem of the chanterelle is actually the resupinate fruiting body of a Tomentella! So this picture represents a mycorrhizal fungus climbing up on the fruiting body of another mycorrhizal fungus to get a better perch from which to dispense its spores!
Oh, and to deal with the charismatic megamycota, the chanterelle is probably an undescribed species.
It’s very cool, so I had to share it with y’all.

grows like this when we see them, like mold – on rotten wood, dung, soil or whatever they come across..
This is usually some crust-like fungus? Where does it usually grow? Although I am not interested in crusts… really, I’m not…
Great documentation. Nice to see clean, clear micrographs.
