lets around the periphery of a spore gives to it-a rather easy mistake
to make if the spores are not stained. Because of the likelihood that
Murrill's collection represented a mixture of two species and that
characters of both were included in the original description, it appears
better to exclude the name than to classify it under M. amicta as a
synonym.
Mycena californiensis (Berk. & Curt.) Saccardo, Syll. Fung., 5: 255.
1887
Agaricus (Mycena) californiensis Berkeley & Curtis, Proc. Am. Acad.,

lamellis liberis albis rubro-marginatis.
"On oak leaves, Mare Island, California.-Differs from A. aurantio-marginatus in the nature of the gills, and is a more graceful species."
It cannot be recognized until the microscopic characters of the
type are known.
Mycena cervinialba Murrill, Mycologia, 8: 220. 1916.
Prunulus cervinialbus Murrill, North Am. Flora, 9: 326. 1916.
"Pileus hemispheric, not fully expanding, gregarious to subcespitose, 1 cm. broad; surface dry, glabrous, conspicuously rugose,
fawn-colored, margin entire, not striate: lamellae adnate with a decurrent tooth, crowded, narrow, pure white: cystidia spindle-shaped,
40-50 X 10-15 u; stipe slender, cylindric, equal, smooth, glabrous,

"Type collected by the roadside in the New York Botanical
Garden, June 14, 1902, F. S. Earle 71 (herb. N. Y. Bot. Gard.).
"Distribution: Known only from the type locality."
The type is sterile. Atkinson (1918) placed the species in Galerula.
Mycena chlorantha Fries.
This name should be discarded because of confused concepts.
See discussions under M. aurantiomarginata and M. citrinomarginata.
