Observation 77046: Pholiota (Fr.) P. Kumm.
When: 2011-09-17
Herbarium specimen reported

Notes: Found under fir and pine.

On rotting logs. When young, very yellow, lemon yellow, in the cap and gills. Mostly gregarious, not fasciculate.

Adding some micro-details:

The first micro-shot is of the gill edge at 400x in KOH. The cheilocystidia are of two kinds, chrysocystidia, and leprocystidia. The chrysocystidia are mostly clavate to random, the leprocystidia are thin-walled, fusiod to fusiod-ventricose, hyaline. The pleurocystidia are all leprocystidia, similar to the cheilosytidia.

The second micro-shot is of the spores from the gill at 1000x in KOH. The spores are ellipsoid, smooth, with a germ pore. The apr. size is 7 × 4 um.

Doesn’t seem to be in Colman’s Thesis on CA Pholiota. Funga Nordica sort-of id’s to Pholiota subochracea, except the spores are wrong, too large, and with a germ pore. Can’t get anywhere with the keys in Smith and Hesler (in general). The descr. in Smith and Hesler for P. subochracea has the cystidia close, but again the spores are wrong. Also the colors and size are wrong too. Not in Noordeloos Strophariacea, and it def. knocks out P. subochracea based on the spores (and the photos there are quite different). So, it was seen a number of times this weekend, but no idea how to id it.

Among quite a few other genera also. But Hypholoma are kinda desc. as having a dark puple-brown-blackish spore print, much like Stropharia. The spore color here is clearly medium brown, putting it more in Pholiota.

elliptic smooth spores with germ pores also.
