Collybidium luxurians (Peck) Murrill 

 Luxuriant Collybidium 



Plate 49. Figure 7. X 1 



Pileus convex to expanded, umbonate, cespitose, 5-8 cm. broad ; 

 surface dry, faintly radiate-striate but not fibrillose, fulvous, with 

 bay umbo, irregular with undulate margin ; context somewhat 

 tough but easily torn, odor pleasant, taste sweetish ; lamellae sin- 

 uate, arcuate, rather close, narrow, crenulate, pallid, becoming 

 discolored; spores oblong-ellipsoid, smooth, hyaline, 7-8X3-4^; 

 stipe twisted, curved, slightly enlarged below, hollow, cartilagi- 

 nous, pruinose, pallid above, tinged with fulvous below, 10-12 

 cm. long, 5-9 mm. thick. 



This species was first described as a Collybia by Dr. Peck in 

 1897 from dried specimens sent him by Dr. Underwood, who col- 

 lected them under brush heaps near Auburn, Alabama, in July, 

 1896. The accompanying illustration and description were drawn 

 from plants collected by Mr. Volkert and myself in weeds at the 

 edge of a sawdust pile near Bronx Park, June 20, 1910. They 

 were found to agree with the type specimens at Albany in all 

 important characters, but are only about one half as large.
