Murrill; Agaricaceae of Tropical North America 35 
microscope, usually i-2-guttulate, 6-7 X 4~5 h- stipe subcylindric, 
slightly enlarged at the base, floccose above, glabrous below, pale- 
yellow, solid, firm, about 5X1 cm. ; veil thick, yellowish, leaving 
an ample, persistent annulus fixed 2 cm. from the apex of the 
stipe. 
Described from specimens collected on the ground under a 
building at Santiago de las Vegas, Cuba, A. Meckleff {Earle 159). 
Also collected later in a nearby field, Earle j/7. 
9. Pholiota Brittoniae sp. nov. 
Pileus large, fleshy, convex to expanded, becoming depressed at 
the center, ceSpitose, reaching 10 cm. broad ; surface dry, im- 
bricate-fibrillose to subglabrous, fulvous, becoming fuliginous or 
blackish with age ; margin entire, concolorous, strongly inflexed 
on drying ; lamellae sinuate, with a decurrent tooth reaching as far 
as the annulus, seceding with age, broad, irregular in shape, sub- 
distant, ferruginous, darker with age ; spores broadly ellipsoid 
to subglobose, conspicuously tuberculate, ferruginous, opaque, 
7-9 IX . ; stipe enlarged below, concolorous, blackening with age, 
longitudinally furrowed, hollow, reaching 10 cm. long and 1-3 cm. 
thick; annulus ample, membranous, ferruginous, persistent, fixed 
near the apex of the stipe ; cystidia none. 
Type collected about the roots of living Eucalyptus trees at 
Cinchona, Jamaica, 5,000 ft. elevation, October, 1908, Elizabeth 
G. Britton ii 32 . Also collected in the same locality at the base of 
a dead standing trunk, December 25, 1908, W. A. & Edna L. 
Murrill 447. Closely related to Gymiiopiltis, but having an ample, 
membranous, persistent annulus. Its nearest relative is probably 
Pholiota ventricosa Earle, described from California, which has 
smaller and more elongate spores. 
12. Hypodendrum Paulet, Icon. 75. 1793 
This genus is distinguished from Pholiota by its densely scaly 
stipe. The pileus may be scaly or smooth. 
Hypodendrum scobifer (Berk. & Curt.) 
A. {Pholiota) scobifer Berk. & Curt. Jour. Linn. Soc. 10: 289. 
1868. 
Described from young specimens collected by Wright about the 
roots of trees in Cuba. About 5 cm. high, pileus 1.2 cm. broad.
