Agaricacese 



Lepiota. on the disk. Gills close, lanceolate, remote, white, then green. Stem 

 firm, equal or tapering upward, subbulbous, smooth, webby-stuffed, 

 whitish, tinged with brown. Ring 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, 

 sordid green, 1013x78/1.. 



Plant 6-8 in. high. Pileus 5-9 in. broad. Stem 6-12 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 dis- 

 covered, and no one of the five series, in which the very numerous species 

 of the genus have been arranged, is characterized in such a way as to 

 receive this species. 



It seems a little hasty to found a series (Viridispori) on the 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 

 which have sordid or yellowish or lilac-tinted spores. 



It gives me great pleasure to dedicate this fine species to its discoverer 

 Mr. Morgan. Peck. 



Commonly 6-8 in. high, 5-9 in. diameter, though larger specimens 

 are sometimes found. It is the most conspicuous Agaric in the meadows 

 and pastures of the Miami valley; it appears to flourish from spring to 

 autumn whenever there is abundance of rain. 



It is heavier and stouter than L. procera and I am disposed to claim 

 that it is the largest Agaric in the world. Spores 10-12x7-8)".. In 

 immature specimens they are greenish-yellow. Morgan.

L. Morgan! is one of the largest, handsomest of the genus. It is 

 very abundant in the western and southwestern states. Mr. H. I. 

 Miller, Terre Haute, Ind., writes August 18, 1898: "I have recently 

 measured several which were more than twelve inches across. At the 

 present time this mushroom is growing in more abundance throughout 

 Indiana than any other. It grows luxuriantly in the pastures, generally
