Mycologia 



Habitat : On damp mucky ground in open woods. 



Distribution : Known only from the type locality. 



The type specimens, collected by Peck in June, are well pre- 

 served at Albany, and seem very near plants called P. atomata 

 Fries by Bresadola. Specimens from Westport so named appear 

 lO be distinct. 



4. Psathyrella minima Peck, Ann. Rep. N. Y. State Mus. 41 : 



70. 1888 



Pileus membranaceous, hemispheric, obtuse, 2-4 mm. broad; 

 surface obscurely striatulate when moist, even and pruinose-ato- 

 mate when dry, dingy-yellow or reddish-brown, becoming^ paler on 

 drying; lamellae broad, adnate, white, becoming yellowish-cinna- 

 mon; spores narrowly ellipsoid, black, 6-8 x 3-4 fx; stipe capillary, 

 minutely mealy or furfuraceous under the lens, pellucid, white, 

 8-12 mm. long. 



Type locality : Adirondack Mountains, New York. 

 Habitat : On manure in woods. 

 Distribution : Known only from the type locality. 

 This tiny species is represented only by a few specimens col- 

 lected by Peck in July and now attached to a sheet at Albany. 



5. Psathyrella hirta Peck, Ann. Rep. N. Y. State Mus. 50: 



107. 1897 



Pileus thin, hemispheric, subcespitose, 8-12 mm. broad; surface 

 hygrophanous, at first covered with erect, fascicled hairs, reddish- 

 brown when moist, grayish-brown or whitish when dry; lamellae 

 adnate or subdecurrent, subcrowded, broad, pallid to black ; spores 

 12-14 x 6-7 fx; stipe flexuous, shining, white, hollow, squamose, 

 2.5-5 cm - l° n &> 2_ 3 mm - thick. 



Type locality : Minerva, New York. 



Habitat : On manured, shaded ground. 



Distribution : Known only from the type locality. 



The type specimens collected by Peck are attached to a sheet at 

 Albany. Others so named collected by Kellerman in October, 

 1906, in a greenhouse at Columbus, Ohio, appear to agree with the 

 type of P. Bartholomaei. 



6. Psathyrella castaneicolor sp. nov. 

 Pileus fleshy, hemispheric to expanded, 3 cm. broad; surface
