portion cylindrical, even, white, confluent with the stem, which is 
abruptly black, passing into greenish white ; spores of an inch. 
Syn. — Geoglossum album , Johnson, Minnes. Myc. n. 630, 1878. 
Mitrula Johnsoni , Sacc., Syll. viii, n. 116, 1889. 
Hab. — On the ground and on fallen wood in woods. 
Distr. — United States (Minnesota, Johnson ). 
Apparently a distinct species, but imperfectly described. Spores 
measuring of an inch is evidently a slip ; but what was intended ? 
Saccardo suggests go^o (=9-10/*), but this is not certain. 
Saccardo’s name was created on account of a previous Mitrula alba , 
W. G. Smith ; the latter, however, being simply a white form of 
Mitrula phalloides , Chev., Johnson’s original specific name has been 
restored.
