Type: in Herb, Schweinitz. 
Fruetifieation effused, membranaceous, separable, drying 
Chaetura-drab to fuscous, the margin much paler, brownish 
and floccose; hymenium distinctly and close- 
ly granular; in section 300-400,» thick, with e 
hyphae 3-4» in diameter, nodose-septate, 
somewhat colored, thin-walled, a few running ZEE 
along the substratum, or forming rope-like 
strands, and sending out suberect, loosely Fig. 17 
. : H. botryoides. 
interwoven branches which form the greater Spore, hyphal 
part of the fructification; KHO solution caus- strandx<640. 
es an immediate change of color in the tissue 
of the granules to between blue-green and sage-green when 
added to bits of the fructification in microscopic prepara- 
tions; spores concolorous with the fructification, angular- 
subglobose, aculeate, the spore body 5-6 X 4-5pm. 
Fruetifieations 1-5 em. long, 1-4 em. broad. 
On rotten wood, both coniferous and frondose. New Hamp- 
shire to South Carolina and Alabama. August to January. 
The fuscous color of the central portion of the fructifica- 
tion, paler margin, and occurrence of granules about 4 to the 
mm. afford a good combination of characters for the recog- 
nition of H. botryoides by microscopic characters. Occasion- 
ally a fructification may vary towards Mars-brown. The 
blue-green color produced in the granules in microscopic 
preparations by adding KHO solution is a good positive char- 
acter for this species, but is merely temporary.
