study will probably show that more of our American species are 
common to both continents. In a few instances where there has 
been confusion of names, American names have been retained for 
species which are apparently found in Europe also. 
A more complete account of the North American species. of 
Marasmius is to be found in vol. 9, pt. 4 of the North American 
- Flora (1915). 
A few species, as M. nigripes (Schw.) Fr. and M. foeti- 
dus (Sow.) Fr., are somewhat gelatinous when they are fresh and 
moist. They have therefore sometimes been considered as belong- 
ing to the genus Heliomyces. Since the species of Heliomyces are 
practically confined to the tropics and the above-named species 
resemble species of Marasmius more than they resemble the typical 
species of Heliomyces, they are here retained in the genus Maras- 
mius. 
The Fresian system of classification has not been found to be 
entirely practicable for’our species. The general arrangement of the 
species from the large Collybia-like forms down to the small forms 
with the tough bristlelike stipe is very similar to the usual arrange- 
ment. Rather more attention, however, has been paid to the stipe 
with respect to its surface, whether rough and hairy or smooth and 
shining, than to the character of the pileus. At its best any system 
of classification is more or less artificial. The present arrangement 
will serve its purpose if it helps the student to identify the species 
of Marasmius as he finds them. 
Maramius Fries 
Gen. Hymen 9g. 1836 
Pileus tough, fleshy to membranous, either continuous with the 
stipe or of a different texture, surface often sulcate or striate, not 
zonate, dry, glabrous or rarely minutely tomentose or pruinose, 
margin involute or straight in young plants, becoming’ broadly con- 
vex, plane or uplifted with the disk elevated or depressed, rarely 
umbilicate; context more or less tough and dry, sometimes soft 
fleshy but not brittle, dry plants reviving when moistened ; lamellae 
dry, rather thin, often of unequal length, often interveined, but 
seldom forking, developing slowly, rarely remaining very narrow, 
almost veinlike; color varying from white to yellow, reddish or 
purplish, often changing in dry plants; stipe central, seldom fleshy, 
tough, horny, stuffed or hollow, often slender or capillary, some- 
times solid, glabrous or more or less tomentose, hairy, or strigose;
