North American species of Mycena.

488 NORTH AMERICAN SPECIES OF MYCENA

because of the poor preservation of the fruiting bodies. Only a few
that were reliable as to shape and size could be found, but it was apparent that the cheilocystidia and pleurocystidia were alike. The gills
had been badly parasitized, and many cystidium-like hyphae apparently belonging to a phycomycete were observed in most mounts.
It is impossible to determine from the type whether the species should
be referred to M. scabripes, M. stannea sensu Smith, or M. aetites sensu
Kiihner.
Mycena prolifera (Fr.) Gillet.
Reported by several investigators but no clear species-concept
exists for the fungus in Europe.
Mycena pulcherrima (Pk.) Saccardo, Syll. Fung., 5: 288. 1887.
Agaricus pulcherrimus Peck, Ann. Rep. New York State Cab., 23: 83.
1872.
"Pileus subcampanulate or convex, rarely subumbonate, striatulate, dull yellow, the disk a little darker; lamellae broad, subventricose, attached to the stem, not uncinate, yellowish; stipe slender,
hollow, concolorous, white at the base; plant gregarious.
"Height 1'-1.5', breadth of pileus 3"-5".
"Under pine trees. Center. October.
"Related to A. acicula, but that has a smaller scarlet colored
pileus."
I have not seen fresh material of the species, and have been unable
to locate the type. The original description is quoted here. As
previously stated (Smith, 1935), the specimens Kauffman referred to
M. pulcherrima are identical with those of M. roseipallens, and there
is no good reason for attributing reddish colors to the former. To
judge M. pulcherrima by its habitat, it could scarcely be considered a
faded M. roseipallens. Since it was described as larger than M. acicula, Peck's species can hardly be the same as M. oregonensis, which,
in addition, is bright yellow and has colored gill margins. To me the
most likely possibility is that M. pulcherrima represents a small
L. flavoalba. However, this cannot be proved. Consequently, the
best course is to regard it as doubtful, at least until the type is found
or fresh material is collected and critically studied.
