It seems to be nearest to L. glabra Murrill, a species from 

 Maine, but differs from it by the gelatinous surface of the pileus, 

 the adnate gills, the much thicker stem and its generally larger 

 size. L. semiglohata Murrill also from Maine, a species with a 

 slightly viscid pileus, has squammules on the pileus, a yellowish- 

 gray stem and ellipsoid, angular spores. Our species has a gen- 

 eral nondescript appearance that allies it to many species of this 

 genus. 



Marasmius limonispora, sp. nov. — Pileus 1-2 cm. broad, 

 submembranous, phant, "light grayish olive" to ''pale smoke 

 gray" (R.) when growing, dingy "pinkish-buff" after reviving in 

 rains, at first even, obscurely radiate-wrinkled in age, the 

 glabrous margin at first incurved; flesh thin, concolor. Gills 

 broadly adnate, relatively rather broad, close, subdistant when 

 pileus expands, whitish, pruinose. Stem 7-10 cm. long, about 

 2-2.5 mm. thick, equal, flexuous below but rather strict other- 

 wise, entirely "natal brown" at maturity, or with white apex, 

 pruinose throughout, tubular, concolor within, with a subfibrous 

 cortex, white-myceloid at the base where it is intergrown with 

 moss and humus. Odor and taste none. Spores limoniform in 

 one view, subplano-convex in other view, 9-12 x 6-7 /x, hyaline, 

 smooth; cystidia scattered on sides and edge of gills, lanceolate- 

 subventricose, capitate, hyaline, 65-75 X 12-15 ju; basidia 4- 

 spored, 40 X 6-7 fx.

Marasmius subnauseosus, sp. nov. — Pileus 5-15 mm. 

 broad, submembranous, broadly convex to flattened, obtuse, 

 *'mars yellow" (R.) on margin, "sudan brown" on disk, glab- 

 rous, dry, even, margin at first incurved; flesh concolor, of 

 uniform thickness. Gills broadly adnate, occasionally with a 

 tooth, color "warm buff," crowded, rather broad behind, nar- 

 row in front, edge entire. Stem 2-4 cm. long, 1-1.5 mm. thick, 

 tapering down from a somewhat dilated apex, instititious, soon
