SUBSECTION HYGROPHORUS 285 



170 



Hygrophorus subpratensis Murr. 



Mycologia3: 199.1911 



Pileus 3-4 cm broad, convex, obtuse, pale fuscous when young, be- 

 coming pallid or whitish with a darker disc, slimy-viscid, pellicle sepa- 

 rable, margin even. Context white, unchanging; odor and taste mild. 



Lamellae deeply sinuate, white, broad, crowded. 



Stipe 3-4 cm long, 3-4 mm thick, white, slimy-viscid, cylindric, 

 equal, spongy-solid. Partial veil slimy-viscid, scarcely leaving an annu- 

 lus. 



Spores 4-5 x 3.5-5 /a, globose to subglobose, smooth, colorless in 

 Melzer's reagent, at times adhering together in fours. Basidia 26—33 X 

 5-6 /x, 4-spored. Pleurocystidia and cheilocystidia none. Gill trama di- 

 vergent. Epicutis of loosely arranged, gelatinous hyphae. Clamps pres- 

 ent on epicuticular hyphae. Stipe exhibiting a gelatinous sheath. 



Habit, Habitat, and Distbibution — On lawns and on banana 

 trash, Cuba, June. 



Matebial Studied — cuba: Earle 68, 373 (type, Santiago de las 

 Vegas, June 1, 1905). 



Obsebvations — The description of microscopic characters given 

 above is based on our study of the type. 



The pileus of the type ( dried ) is "ochraceous tawny," and super- 

 ficially resembles H. pratensis, but differs in its divergent hyphae of 

 the gill trama, its globose to subglobose spores, and slimy-viscid stipe. 



Dennis ( 1953 ) says the spores in deposit are white, becoming yel- 

 lowish with age.

Pileus 2.5-3.5 cm broad, at first nearly hemispheric, finally plane 

 with a drooping margin, gray-drab or grayish brown, at all ages, viscid, 

 fibrous, margin incurved and felted-spongy, the marginal fibrils repre- 

 senting an ephemeral veil. Context pure white, firm, about 5-6 mm 

 thick near the stipe, rapidly thinning toward the margin; odor strong 

 of bitter almonds, taste mild.
