Pholiota aurivella

Scientific name:  Pholiota aurivella (Fries) Kummer
Derivation of name:  Aure- means "gold" or "golden" and
vell- means "fleece." Aurivella, then, means "golden fleece."
Synonyms:  P. adiposa; P. squarrosa-adiposa.
Common name(s):  Golden Pholiota.
Phylum:   Basidiomycota
Order:   Agaricales
Family:   Strophariaceae
Occurrence on wood substrate:  Saprobic/parasitic;
typically in clusters on dead or living deciduous or conifer
wood; July through November.  
Dimensions:  Caps 4-15 cm wide; stipes 5-7.5 cm long
and 5-15 mm thick.   
Cap:  Sticky to slippery/slimy; yellow to yellowish-orange;
surface covered with large, flattened, wine-red scales.
Gills: Attached; yellowish at first, becoming rusty-brown.
Spore print: Brownish.
Stipe:Dry; colored like the cap or paler; scaly below the
ring, whitish above the ring.
Veil: Fibrous, whitish, partial veil leaving an evanescent ring or
zone of fibers on the upper stalk.
Edibility: Although some people eat it, it is not
recommended as there are reports of gastric upset following
ingestion.
Comments: Michael Kuo makes the point in the website
below that there is usually enough uncertainty due to age,
variable and overlapping traits, and weather conditions,
that microscopic analysis may be required to confirm
identifications for this and most Pholiota species. For
example, Pholiota aurivella is similar in every way to
Pholiota limonella except for smaller spores.

flattened. Also, scales can be washed off in a rain which
can complicate the identification process.
