Collection location: Howarth Park, Santa Rosa, Sonoma Co., California, USA [Click for map]

Who: Debbie Drechsler (debdrex)

No specimen available

Fruiting in an area covered in wood chips under live oak. I thought these would be easy to identify but am stumped! Larger one in drawing was 4cm tall, the button was 3.3cm tall.
Pileus: Viscid when wet, convex then plane with the umbo slightly depressed. Veil apparent on buttons but no sign on older specimens. Button 1.7cm across, older one 2.8cm across.
Gills: yellow, turning rusty brown as spores disperse. Decurrent.
Stipe:bright yellow at apex with very few fibrils, colored brown by spores. Becoming reddish brown and then dingy brown. Wider at apex which was .7cm across on button and .6cm on older one.
Spores: Rusty brown.
I’ve added an image (9488) taken 12/21/07.
When I first saw these I thought they might be Hypholoma fasciculare, but the spore color blew that theory. When I tried to key them in Arora I ended up at Pholiota malicola but didn’t quite trust it. But I don’t remember why.
12/24/07: I’ve added two images of the gills and underside of the pileus.

Pholiota malicola group?

Without seeing the underside I can’t really tell, but the latest image suggested H. fasciculare to me, but the spore color is wrong. Reading that description in Arora he suggests Pholiota malicola group (pg. 388) as similar but with brown spores.
