Microglossum obscurum 



Clubs 8-12 mm. long, about 2 mm. broad, compressed, ob-

 as the club, olive brown or blackish brown; asci clavate, 100-112 

 /^ long ; spores fusiform, slightly curved, hyaline, 12-15 

 4-5 p, broad.

Gregarious or cespitose in thickets, Canada. August.

The w^hole fungus is scarcely more than 2 or 2.5 cm. long.

 spores are more narrow. From the very \-ariable M.
