Murrill : Dark-Spored Agarics 



265 



The type specimens collected by Lloyd (3480) in April are 

 fairly well preserved at Albany. Kauffman says it occurs rarely 

 in Michigan, having been found by him (365) growing in turf at 

 Ann Arbor, in October, 1905. Some of his specimens determined 

 by Peck are at Albany. They are thinner and more slender than 

 the types. 



2. Atylospora vestita (Peck) comb. nov. 



Psathyra vestita Peck, Bull. N. Y. State Mus. 105 : 28. 1906. 



Pileus thin, submembranaceous, ovoid, conic or subcampanulate, 

 obtuse, 8-16 mm. broad; surface at first covered with white, floc- 

 cose fibrils, usually with a rufescent tint, soon paler or white and 

 silky-fibrillose, sometimes slightly striate on the margin; lamellae 

 thin, narrow, close, adnate, white when young, becoming blackish- 

 brown; spores ellipsoid, purplish-brown, 7.5-10 x 5-6^; stipe 

 equal, hollow, flexuous, white, floccose-fibrillose, becoming silky- 

 fibrillose, mealy and often striate at the apex, 2.5-4 cm. long, 2-3 

 mm. thick. 



Type locality : North Elba, New York. 



Habitat : On fallen leaves and grass. 



Distribution : Known only from the type locality. 



Type specimens collected by Peck in September, 1905, are well 

 preserved at Albany, appearing much like a small form of Droso- 

 phila appendieulata. Kauffman recognized P. semivestita as oc- 

 curring in Michigan and remarks that P. vestita is " very similar, 

 if not the same, but the spore-sizes are given somewhat smaller. " 



3. Atylospora multipedata (Peck) comb. nov. 

 Psathyra multipedata Peck, Bull. Torrey Club 32 : 80. 1905. 



Pileus submembranaceous, conic or hemispheric, densely cespi- 

 tose, forming tufts of many individuals, 12-16 mm. broad; sur- 

 face glabrous, hygrophanous, light-bay or tawny when moist, cine- 

 reous when the moisture has escaped, the center retaining its 

 moisture longer than the margin ; lamellae thin, close, adnate, pallid 

 or gray becoming brown, whitish on the edges ; spores brown, 

 ellipsoid, 6-8 x 4-5^; stipe slender, equal, hollow, brittle, furfura- 

 ceous, becoming smooth or sometimes remaining fibrillose near the 

 base, pure-white, 5-10 cm. long, 2 mm. thick. 



Type locality : St. Louis, Missouri. 

 Habitat : In grassy ground.
