352 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Fructification is in fragments, but perhaps about 6 cm. in 
diameter originally. 
On charred wood in hollow of Sequoia sempervirens. Cali- 
fornia. February. 
The principal characters of this species are small, shallow, 
hexagonal pores, the buffy brown color throughout and at the 
margin—much paler, however, in the case of individual 
hyphae and spores under high magnification—, and the ab- 
sence of thick-walled, deeply colored, rigid hyphae. М. hez- 
agonoides does not closely resemble in aspect or structure any 
other of our species known to me.
