100 PecK: New SPECIES OF FUNGI 
larger specimens there are one to four perforations at the base, 
but no chinks as in IZ. rimosipes. The inner surface of the stem 
is glabrous. 
Mitruliopsis gen. nov. 
Ascomate fleshy, obovate or spathulate, stipitate ; asci 8-spored, 
aparaphysate ; spores filiform. 
A genus related to Mitrula and Spathularia, but with filiform 
spores. 
Mitruliopsis flavida 
Ascomate fleshy, soft, tender, stipitate, very variable, obovate 
or subspathulate, terete or compressed, sometimes lobed at the base 
and decurrent on the stem, creamy yellow, flesh white ; asci sub- 
fusiform, 120-160 » long, 8-spored; spores filiform, hyaline, 
60-80 long, 2 4 broad; stem equal or slightly tapering upward, 
pallid, hollow, 12-20 mm. long, 2-3 mm. thick. 
Steep shaded banks. Near Moscow, Idaho. Autumn. L. 
F. Henderson. The hymenium is distinct from the stem and often 
lobed at the base. When the club is compressed the lobes are 
generally decurrent and then the fungus might easily be taken to 
bea species of Spathularia. 
Helvella brevissima 
Pileus irregular, convolute, with the deflexed margin free, 
blackish when dry, whitish or pallid beneath, 1-2 cm. broad ; 
stem very short, even, solid, whitish or pallid, 1-1.5 cm. long, 
3-4 mm. thick ; asci cylindric ; spores elliptic, commonly binu- 
cleate, 15-20 w long, 10-12 broad ; paraphyses filiform, thickened 
at the top and there brown. 
Ground. California. W. R. Dudley. 
Plectania rimosa 
Cups 1.5—2.5 cm. broad, cupulate, the margin involute, exter- 
nally minutely hairy, black, with a few simple or sparingly- 
branched costae extending upward from the base, hymenium 
black, rimose ; stem short, irregular or compressed, often tapering 
downward ; asci cylindric; spores unequally elliptic or oblong, 
two- to four-nucleate, uniseriate, 22-30 » long, 12-14 » broad, the 
brown paraphyses slightly thickened above. 
California. W. R. Dudley.
