Hi all, Third batch here - found in the same area as the first two batches. Any insight would be much appreciated!




Habitat: Found in Sutro Heights Park, San Francisco, CA, in a bed of wood chips where there were also different kinds of mushrooms (posted in my other threads), along with some flowers
Gills: The gill color varies from a white to a greyish color. The gills are free.
Stem: Most stems are around 7-9 cm in length and 0.4 cm in diameter. Stems are a white color, feel hollow, and are pretty thin, relative to the size of the cap.
Cap: Most caps are around 1.75-2.0 cm in diameter, light brown / creme in the center, and darken to a brown color around the edges. They appear to be more conical.
Spore print color: Looks to be a dark brownish color.
Bruising: No bruising that I could tell
Other information: When I scratch the stem, it just appears to be white (no yellow stain or inky smell).

His P. gracilis is probably not that species and his P. conopilus is probably P. atrospora.
Edit: His P. gracilis is probably P. gracilis sensu lato as he says here.
"The cluster of species around Psathyrella gracilis forms a well supported molecularly clade, packed tightly with several species that intergrade quite well. Various identification schemes have been proposed, based on micro- and macromorphological features, but most are contradictory and none seems quite convincing. Such factors as the amount of partial veil remnants on the cap, rooting stem, reddish discoloration of the gills, size, density of the cheilocystidia, etc have been factored. Since there is a great deal of confusion in the literature while new and defining morphological breakthroughs are lacking, I'm forced to treat them as a complex."
Edit2: His P. longipes probably is Coprinopsis marcesciblis & those names very well could be synonyms. Also his P. longistriata needs micro & he seems to have the same "P. uliginicola" with hyaline spores without a germ pore as you which doesn't match Smith's description, illustration & possibly his photos for one reason or another...
