wards, subbiilbous. smooth, webby-stufFed, whitish, tinged with 

 brown ; annulus rather large, movable ; flesh both of the pileus and 

 stem white, changing to reddish and then to yellowish when cut or 

 bruised; spores ovate or subelliptical, mostly uninucleate, .000-1- 

 .0005 of an inch long, .0003-.00032 broad, sordid green. 



Plant six to eight inches high, pileus five to nine inches broad, 

 stem six to twelve lines thick. 



Open dry grassy places. Dayton, Ohio. A. P. Morgan. 



This species is remarkable because of the peculiar color of the 

 spores. No green-spored Agaric, so far as I am aware, has before 

 been discovered, and no one of the five series in which the very nu- 

 merous species of the genus have been arranged, is characterized in 

 such a way as to receive this species. The subgenus Lepiota, to which 

 our plant clearly belongs in every respect except in the color of its 

 spores, pertains to the Leucospori or white-spored series. This series 

 is characterized as having "spores white, rarely whitish," the whitish, 

 (albidjTs) as explained by Fries, including such spores as have the 

 color sordid or inclining toreddisli, (sordida? 1. in rubellum vergentes). 

 Nothing is said about green spores. Shall we then institute a green- 

 spored series (Viridispori) for the reception of this new Agaric? It 

 is not yet shown that such a series exists in Nature, although this 

 plant may be an indication of it, and it seems a little hasty to found 

 a series on tiie strength of a single species. Until other species of 

 such a supposed series shall be discovered it seems best to regard this 

 as an aberrant member of the white-spored series. The same course 

 has been taken with those Agarics that have sordid or yellowish or 

 lilac-tinted spores. In this view of the case our plant is readily re- 

 ferred to the first section (Procerl) of the subgenus Lepiota., and 

 should, in my opinion, stand next to Agaricus inolyhditcs in which the 

 lamellfTe are said to become blue. 



It gives me great pleasure to dedicate this fine species to its dis- 

 coverer, Mr. Morgan, who has kindly submitted to me a description 

 and figure of the fresh plant, from which description and figure the 

 preceding diagnosis was chiefly derived. In the dried specimens the 

 lamellae have assumed a dull brownish-green hue. 



Meeulius sulcatus. — Thin, fleshy or subcoriaceous, efFuso-reflexed ; 

 pilei narrow, imbricated and subconfluent, concentrically sulcate, 

 villose, wavy, whitish varied with yellowish and brownish tints, the 

 extreme margin white when young; hymenium pallid, tinged with 

 browMiish or pinkish hues, concentrically sulcate, gyrose-reticulate 

 with crowded folds.
