Pseudorhizina sphaerospora (Peck) Pouzar, Česká Mykol., 15: 45 (1961).

 

Basionym Helvella sphaerospora Peck, Annual Rep. N.Y. State Mus., 27: 106 (1875).

Diagnosis Pileus large, irregular, ochraceous, the margin free, somewhat veiny and minutely tomentose beneath ; stem stout, deeply lacunose, smooth or with a minute appressed tomentum, white; asci cylindrical ; spores globose, .00035'-.0004' in diameter. Plant 3'-4' high, pileus 3-4' broad, stem 1-2' thick.
Old stumps in woods. Indian Lake. July.
In the dried specimens the pileus becomes darker, so that the colors resemble those of H. esculenta, but the true relationship is with H. costata. The globose spores are peculiar and suggest the specific name.

Type ex herb. Peck (NY) - holotypus
