H a b . On the dead leaves of various species of Fir (Pinus), in Autumn and
Spring. Fxtremely common.
Minute, oval or elliptic, depressed, blackish-grey towards the margin, which
is almost always plane, aud frequently bounded by a small, shghtly raised
black line. The centre is somewhat raised and black, rarely shining.
Orifice not extending to either extremity, often a small part only of the

obtuse. Sporules oval.
