Lentinus strigosus

Scientific name:  Lentinus strigosus Fr.
Derivation of name:   Strigos- means "having coarse
flattened, rigid hairs or bristles" (stigose) in reference to the
hairy caps and stipes of this mushroom.
Synonyms:  Panus rudis Fr.
Common name(s):  Ruddy panus.
Phylum:   Basidiomycota
Order:   Polyporales
Family:   Polyporaceae
Occurrence on wood substrate: Saprobic; solitary but
mostly clustered on deciduous logs and stumps; May
through November.  
Dimensions:  Caps 2.5-7.5 cm wide; stipes (when
present) 1-2 cm long and 0.3-1 cm thick.   
Cap: Pinkish-tan to reddish-brown with violet tints when
young, tan with age; dry; densely hairy and velvety.        
Gills: Decurrent; white to tan
Spore print: White.
Stipe: If present, pinkish-brown to tan, densely hairy;
stubby; lateral to off-center.
Veil: Absent.
Edibility: Edible.
Comments: The degree of color change is remarkable
and can occur in the course of a single day. DNA
information places this gilled mushroom among the
polypores, indicating the independent evolution of
gills.
