Pholiota spp.

Scientific namesKuehneromyces vernalis
(Sacc.) Singer & A.H. Sm. (= P. vernalis);
Pholiota spumosa (Fr.) Singer; Pholiota
(Pers.) Kuyper & Tjall.-Beuk.;
Pholiota polychroa (Berk.) A.H. Sm. &
H.J. Brodie; Kuehneromyces mutabilis
(Schaeff.) Singer & A.H. Sm.
(= P. mutabilis);  Pholiota highlandensis
(Peck) A.H. Sm. & Hesler; Pholiota flavida
(Schaeff.) Singer; Hemistropharia
(Peck) Jacobsson & E.
Larss. (= P. albocrenulata).
Derivation of namesVernalis pertains to
spring. Spumosa means "foamy" or "foaming."
Populnea refers to poplars and aspens.
Polychroa means "many colors." Mutabilis
means "changeable." Highlandensis means ?.
Flavida means "yellowish." Albocrenulata
means "white notched."  
Phylum:   Basidiomycota
Order:   Agaricales
Family:   Strophariaceae
Occurrence on wood substrate: Saprobic;
many grow in clusters on deciduous wood
and/or conifers but some are terrestrial,
growing from buried or burned wood;
spring through fall depending on the species.
Dimensions: Consult field guides.
Cap: Many of the large specimens have scaly
and/or slimy caps but some species have smooth
Gills: Attached
Spore print:
Brown to rusty-brown to
Consult field guides.
Veil: Evidences of partial veils (rings, ring zones)
and/or universal veils (scales) evident in young
Edibility: Some species are edible and some
are poisonous.
Comments: Few Pholiota species can be identified
with certainty apart from microscopic examination.
This is true even of P. aurivella which can be
indistinguisable macroscopically from P. limonella.
In situations of confusion with Gymnopilus spp.,
Pholiota spores are smooth and an apical pore is
