Observation 217294: Cortinarius (Pers.) Gray

Notes:
[OMS Mycoflora field trip]

Growing insititious on a conifer log. Sorry I picked them carelessly; didn’t think at first I would save them.

Thanks to all who’ve been helping with the id here. Oluna and Adolf, thanks for pointing out the possibility of mycorrhizal growth on wood.

The spores are 8-10 × 5-6, elliptical, with visible hilar appendix. Browin, but not dark. To my eyes, they are smooth. I cannot post photos because my camera software didn’t work tonight (a suspicious file discovered and deleted). Also, there are no cheilocystidia.

I think we can at least eliminate Gymnopilus.

Some Cortinarius species can grow on decaying wood

see for instance Cortinarius ceskae, Cortinarius humboldtensis, or Cortinarius idahoensis:

In such instances, these fungi are still mycorrhizal with tree seedlings that germinated on decaying logs

I didn’t do a good job picking this one, so it’s hard to be certain that it’s being lignicolous or not. However, it was certainly growing from the wood and difficult to pull without breaking. That wood was a log, not very decayed, and the mushrooms were growing on its side, at least 30 cm above the ground. Can a mycorrhizal cort grow like this?

Dimitar should have a look

Lignicolous doubt…

that’s why I only gave it a Could Be. Could it have been decomposing a thin layer of other organic matter stuck to the wood? Is there anything it could be other than a Cort? They look profoundly Corty…

Can Corts grow on wood?
