Hypomyces purpureus Peck, Bull. Torrey Club 25: 327. 1898. 
Stromata thin, effuse, covering the hymenium and stem of the host and entirely 
obliterating the gills, bright-orange, the color changing to bright-purple as the host 
decays ; perithecia thickly scattered, immersed or with the necks slightly protruding, a little 
darker than the subiculum; asci very long, cylindric; spores 1-seriate with the ends 
overlapping, fusiform with an apiculus at each end, for the most part slightly curved or 
unequal-sided, with a medial septum, hyaline and strongly roughened at maturity, 35-40 x 
7-8 #, oozing from the perithecia and forming a white powder over the surface of the 
stroma. 
Parasitic on species of Lactaria.

Stromata effuse, soft, subfleshy, occurring in irregular patches, at first bright-orange 
with the margin sterile and lighter, the color very variable, in dried specimens fading to 
pale-orange, dull-yellow, and finally dirty-whitish especially when exposed to the light; 
perithecia thickly scattered, immersed with the necks protruding, darker than the subi- 
culum ; asci cylindric ; spores 1-seriate with the ends overlapping, fusiform with an apicu- 
lus at each end, usually a little curved, with a medial septum and slightly constricted, 
hyaline, 25-35 X 7-8, becoming a little rough at maturity.
