340 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
the Swedish specimens of M. serpens received from Romell 
the pores are about 2-3 to a mm., the fructification is about 
400 р thick, has ап Isabella-colored middle zone, and its 
hyphae are regularly nodose-septate. Specimens of M. ser- 
pens as understood by Bresadola and collected by him at 
Trento, Austria-Hungary, have hair-like cystidia and lack an 
Isabella-colored middle zone in the stained sections. M. cer- 
acellus appears to be a well-characterized American species.
