Taxonomique sur les Hyménomycetes, p. 143, Patouillard in- 
cludes here species of Collybia, Marasmius, and Lentinus, 
some of which would be excluded under the above definition. 
29. EOMYCENELLA Atk. Bot. Gaz. 34: 37. 1902. 
Pileus thin, of interlacing threads, trama rudimentary (re- 
viving?): lamellae rudimentary, often wanting, hymenium 
deliquescent: spores white: veil none: stipe very slender, 
fleshy. 
Type, &. echinocephala Atk. loc. cit. 
The genus is monotypic and its true relationship is very 
doubtful. The one known species is very minute, the pileus 
being less than 1 mm. broad and the stipe only 34 mm. high. 
It is figured as glandular-hirsute throughout. 
30. COLLYBIOPSIS (Schroet.) gen. nov. 
Marasmius § Collybropsis Schroet. Krypt. Fl. Schles. 3): 
559. 1889. 
Pileus thin, reviving, margin at first incurved, epelliculose : 
lamellae adnate or decurrent: spores white: veil none: stipe 
central, tubular, slender. 
Type, Marasmius ramealis(Bull.) Fries, Epicr. 381. 1838. 
(Syll. 5: 531.) 
This corresponds to Marasmius § Collyéta, subsection 
Calopodes, of the Sylloge. It is distinguished from Scor- 
teus by the adnate or decurrent lamellae. 
31. SCORTEUS gen. nov. 
Pileus thin, but somewhat fleshy, reviving, the margin at 
first incurved, epelliculose, usually glabrous: lamellae free or 
slightly adnexed: spores white: veil none: stipe central, 
tubular or of compacted fibers, usually elongated. 
Type, Marasmius oreades Fries, Epicr. 375. 1838. (Syll. 
5: 510.) 
In the segregations heretofore proposed for Marastmus no 
name has been given to this group. As here understood it 
includes § Co//yéza and subsections Scortes and Terginz, of 
the Sylloge.
