Hypholoma sublateritium

Scientific name:  Hypholoma sublateritium (Fr.) Quel.
Derivation of nameSub- means "somewhat" or
"almost" and  laterit- means "brick-colored." So, this
mushroom was judged to be nearly brick-colored by the
name's author.
Synonyms:  Naematoloma sublateritium (Fr.) P. Karst.
Common name(s):  Brick cap; Brick tops.
Phylum:   Basidiomycota
Order:   Agaricales
Family:   Strophariaceae
Occurrence on wood substrate:  Saprobic; in clusters
on decaying deciduous stumps, logs, or standing dead
trees; August through November.  
Dimensions:  Caps 4-10 cm wide; stipes 4-10 cm long
and 0.5-1.5 cm thick.   
Cap: Moist; brick-red but paler toward margin.        
Gills: Attached; Whitish to pale greenish-yellow,
becoming purplish and finally purple-brown as the spores
mature.
Spore print: Purple-brown.
Stipe: Whitish or pale yellow above, grayish to brownish
to reddish brown toward the base
Veil: Partial veil leaves a fibrous zone near the stalk apex
which may become purple-brown following deposition of
spores.
Edibility: Field guides give mixed reviews as to the
edibility of this mushroom.
Comments: Lincoff states the species is only tasty when
very young. Miller indicates the species is bitter and inedible.

due to the dark environment inside the hollowed log.

Figure 11. The partial veil may leave a fibrous zone near
the stalk apex. This zone may become purple-brown
following deposition of spores. Because the presence of
this annular zone is a variable trait, this species keys out
with mushrooms having partial veils and with those
lacking veils. Photo © Gary Emberger.

deposited on the caps of mushrooms positioned below
the gills of other mushrooms. The dark purple-brown
spore deposits observed on these caps provide a
convenient spore print for this species. Photo © Gary
