180 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



Dr. Stevens for himself and the Bernice Pauahi Bishop Museum 

 Herbarium. The following descriptions and notes are based on 

 characters retained by the dried specimens. 



AGARICACEAE 



Lepiota xylophila Peck, Torr. Bot. Club Bui. 34: 97. 1907. 

 Type: in Mo. Bot. Card. Herb., 3365, and probably in N. Y. 



State Mus. Herb. 



"Pileus thin, campanulate or convex, umbonate, minutely 

 squamulose, white or whitish and even on the margin when 

 fresh, becoming brownish with age or in drying, with the umbo 

 darker and the margin widely and distinctly plicate-striate; 

 lamellae rather narrow, free, denticulate on the edge, minutely 

 pulverulent, whitish, faintly tinged with yellow or greenish- 

 yellow; stem slender, equal or nearly so, hollow, pale-yellowish 

 or greenish-yellow; spores elliptic, uniguttulate, 8-12^ long, 



6-7 [i broad. 

 "Pileus 2-4 cm. broad; stem 2-4 cm. long, 2-4 mm. thick. 



"On wood of red fir, Douglas fir and redwood. Hawaii. Col- 

 lected by N. A. Cobb; communicated by H. von Schrenk." 



Peck added further that this species is closely related to 

 L. cepaestipes, from which it may be separated by its different 

 colors, its peculiar habitat, the even margin of the fresh pileus, 

 and its stem, which is not enlarged at the base. To this species 

 I refer two more recent gatherings, the one without definite 

 Hawaiian locality, F. L. Stevens, 232; the other, on lawn, Kame- 

 homeha School grounds, Oahu, Forbes & Stokes, 2196.0. These 

 later collections agree well with the type, but it seems probable 

 that at least those labelled "on lawn" were growing on the 

 ground. 



Pleurotus ostreatus Jacqu. 



Lanai, G. C. Munro, 4.L; Molokai, C. N. Forbes, 6.M; C. N. 

 Forbes, 13a-S. 



Pleurotus flabellatus Berk. & Br. 



F. L. Stevens, 319, 668, 695, 750, 950, 997, 1149, 1151. 



Pleurotus sp. 



On bark, F. L. Stevens, 592.
