Observation 11476: Hypholoma (Fr.) P. Kumm.
When: 2008-09-21
No herbarium specimen

Notes: Small brown mushrooms growing on a rotting log. The cobwebby partial veil evident in the third photo places them in the Cortinariaceae but the growth on wood seems to suggest that they’re not actually in the genus Cortinarius.

One Inocybe and some Galerina and Gymnopilus species turned up when I cast my net a bit wider, as able to grow on wood and show a cort-like partial veil. They ranged from hallucinogenic (Gymnopilus sp.) to poisonous (Inocybe lanuginosa) and even deadly (Galerina marginata), so it looks like these sorts of mushrooms are fit only for photography!

The actual appearance of the mushroom: looks too brown to be Gymnopilus and the cap isn’t fibrous to scaly like Inocybe. What I can see of the gills suggests that they are yellow (but they probably turn brown as the spores mature).

Perhaps also my field guide is incomplete, and some Cortinarius species do grow on wood. (If so, not only does it not list any such species, but the key in the back is wrong, as it implies that no member of the genus grows on wood. Then again, it does the same for Russula…)

There had been a thunderstorm at around 4:30 PM on the twentieth, with quite a hard rain. Total rainfall where I live was minor, but in Pembroke it exceeded half a centimeter according to official (Environment Canada) records.

So it may not be that surprising that I found at least ten distinct species of mushroom within a region of only a few square meters in one of the damper parts of those woods when I went there the next day. Besides the brown mushrooms:

On a nearby log was a pink mushroom (obs. 11478) and close by were some scattered yellow mushrooms (obs. 11467).

Not far away was a bolete (obs. 11479), an earth tongue (obs. 11486), some cup fungi growing on wood (obs. 11485), and at least four agaric species (obs. 11480, 11481, 11482, and 11483).

There were more agarics nearby that I ignored, so the total species count was probably closer to 15 than 10.
