North American species of Mycena.

EXCLUDED AND DOUBTFUL SPECIES

group. Patoulliard's comparison of his species to A. calopus was a
bit unfortunate, but certainly does not justify transferring the fungus
to Mycena (Prunulus), as Murrill did. At present A. calopus Fries
is regarded as a robust form of M. inclinata. Patouillard possibly confused Marasmius cohaerens with Mycena calopus.
Mycena cruenta (Fr.) Quelet, Champ. Jura et Vosges, p. 107. 1872.
This is a poorly known species, possibly identical with M. haematopus.
Mycena cymbalifera (Mont.) Saccardo, Syll. Fung., 5: 273. 1887.
Agaricus (Mycena) cymbaliferus Montagne, Syll. Crypt., p. 110. 1856.
Prunulus cymbaliferus Murrill, North Am. Flora, 9: 331. 1916.
"Pileo membranaceo convexo explanato ample umbonato margine
undoso patente striatulo ex albo griseo, sicco fuscescente; stipite
longissimo fistuloso fragili basi decumbente fusiformi-incrassato longe
radicato fibrilloso; lamellis didymis linearibus angustissimis utrinque
attenuatis haud affiixis albis.

"Obs. Cum cymbalis musicae militaris quoad formam pilei comparandus. Pileus 1-2- centim. latus, umbone 6-8 millim.-Stipes
cum parte ejus radiciformi 15 centim. longus, 2 millim. crassus."
This is the original description. Nothing more is known of the
species. I tried to locate the type but was not successful. The
species might possibly be the same as M. fagetorum or M. megaspora,
but the latter is not fragile-a character specifically mentioned in the
description. Consequently, since the Ohio fungus cannot be identified with any other species and has never been recognized for certain
after it was described and since the description is inadequate, the
name should be dropped.
Mycena dilatatus (Fr.) Gillet. Reported by Harkness and Moore
(1880).
Mycena discopus (Lev.) Quelet.
Reported by Peck in 1885. Probably M. stylobates.
Mycena discreta (Fr.) Saccardo, Syll. Fung., 5: 260. 1887.
Agaricus discretus Fries, Elench. Fung., p. 20. 1828.
