ellipsoid to oval, rough, dark rusty under the microscope, 7-8 X 5- 

 5.5(6) At; cystidia none, or few to scattered, short subcylindrical 

 and subcapitate, hyaline; sterile cells on edge of gills nine-pin- 

 shaped, hyaline, obtuse ; basidia 32-34 x 6-7 fx ; surface of pileus 

 corticate, composed of pyriform, brown cells. 



On decayed coniferous wood. Mt. Hood, Oregon, October 10.

Very similar in size and coloring to our eastern species, A^. 

 hellula Pk., but differs by its larger spores, adnexed gills, etc. 



NoLANEA PASCUA Fr.-Ricken. — This is a rare species, at 

 once distinguished microscopically by its cruciate-angled spores. 



Nolanea latifolia, sp. nov. — Pileus 2-3 cm. broad, com- 

 panulate-hemispherical, apex truncate-depressed, in age some- 

 times markedly umbonate but umbo truncate, glabrous, hy- 

 grophanous, striatulate to subeven and "hair-brown" when moist, 

 quickly fading to "drab-gray" or ashy on losing moisture, then 

 even, margin at first straight; flesh submembranous, concolor. 

 Gills broadly adnate-seceding, broad, ventricose, abruptly sinu- 

 ate near stem, close, at first gray-tinted, then " vinaceous-f awn " 

 (R.), somewhat crisp. Stem 5-6 cm. long, 2-3 mm. thick, strict, 

 equal, elastic, cartilaginous, stuffed to hollow, fragile, persist- 

 ently grayish-brown to "hair-brown," variegated with silky- 

 white innate fibrils, white-myceloid at the slightly enlarged base. 

 Odor and taste none or shghtly subnauseous. Spores spherical, 

 obtusely angular, tinged flesh-color, 8-9 fj, diameter, (10 fx with 

 apiculus); cystidia none; basidia 4-spored, 40-42 x 11-12 fi. 



Among moss and debris in forest of fir and hemlock. Solitary 

 or subgregarious. Mt. Hood, Oregon. October 7 and 25. 

 Collected by C. H. Kauffman. 



I am not at all sure that this may^ not be N. occidentalis 

 Murrill, but if so, that species is very imperfectly described. It 

 differs from Murrill's account by the definitely adnate gills 

 which are closely spaced, not at all distant, and by the fact that 

 they are at first grayish.
