Murrill: Agaricaceae of Tropical North America 25 
yellowish-white, mild to the taste ; lamellae short-decurrent, 
crowded, of medium width, pale-ochraceous to bright-ferrugi- 
nous ; spores ellipsoid, conspicuously echinulate, ferruginous, 
9X5/*; stipe subcylindric, concolorous or paler, slightly fibrillose, 
solid, 3 cm. long, 5 mm. thick; veil thick, membranous, forming 
an annulus, at least in young sporophores. 
Type collected on a dead royal palm trunk at Managua, Cuba, 
May 25, 1906, C. F. Baker (F. S. Earle 5-?7). The young sporo- 
phores show a well-developed annulus, as in Pholiota. 
23. Gymnopilus carbonarius (Fries) Murrill, Mycologia 4; 256. 
1912 
A terrestrial species common throughout temperate North 
America and Europe. It was found in ashy ground by a burnt 
log, growing in groups or clusters. The elevation of Chester Vale 
is 3,000 ft., just sufficient to insure a subtemperate climate. The 
fondness of this fungus for charcoal is quite remarkable. For a 
description and colored figure of the species, see Mycologia for 
July, 1912.

24. Gymnopilus jalapensis sp. nov. 
Pileus expanded, at length depressed at the center, reaching 8 
cm. in breadth; surface smooth, moist, glabrous, cremeous at the 
margin, ochraceous near the center and ferruginous-isabelline 
to fulvous at the center, slightly greenish when bruised ; margin 
curved downward and irregular or undulate ; context white, mild, 
5 mm. thick behind ; lamellae adnate, close, ventricose behind, 
arcuate near the margin, stramineous, about 5 mm. broad ; spores 
ellipsoid, smooth, subhyaline but with a distinct ferruginous tint, 
6X3-5/i; cystidia abundant, flask-shaped, 60-75 X 15 mostly 
empty and hyaline, with short stalks and long, slender, septate 
necks filled with yellowish contents ; stipe equal below, slightly en- 
larged at the apex, glabrous, stramineous, with a trace of a slight 
cortina at the middle, reaching 8 cm. long and i cm. thick. 
Type collected on the ground in leaf-mold in a dense virgin 
forest near Jalapa, Mexico, December 12-20, 1909, W- A. & Edna 
L. Murrill 78 {type), 81. The lamellae and spores are paler than 
in other American terrestrial species.
