lamellated upper surface of the rather thick membranous annulus. 

 These lamellae are uneven on the edge, and in some cases they appear 

 to extend upward on the stem till they meet the true lamellae. 



From further gatherings made in Washington, D. C., and Newark, 

 Wayne county, New York, Prof. Peck draws another description (Rep., 

 1907: 139) as follows: 



Pileus fleshy, convex, becoming nearly plane in larger plants, even, 

 obtuse, glabrous, whitish or yellowish. Flesh white. Lamellae thin, 

 close, adnate, purplish brown in the mature plant. Stem commonly 

 short, solid, sometimes hollow in large plants, white, annulate, the 

 annulus thick, white, with la'mellae on the upper surface. Spores 

 elliptic, .0004 to .0005 of an inch long, .0002 to .0003 broad. 



Prof. Peck further remarks upon this characteristic species as follows : 

 "The species is well marked by the peculiar character of its collar. On 

 the upper surface are miniture gills which radiate from the stem to the 

 margin of the collar. These are narrow, white and uneven or dentate 

 on the margin. They are sometimes stained by the spores, but these 

 have probably fallen from the true gills above. In some instances the 

 inner extremity of the false gills extends upward on the stem and ap- 

 pears to connect with the gills above. This peculiar character of the 

 collar seems to be shown in Stropliaria coronilla (Bull.) Fr. and forcibly 

 suggests the thought that our plant is specifically the same as the 

 European." 



Prof. Peck, loc. cit. draws a table of comparative characters between 

 the American and the European species, and concludes that while there 

 is a strong similarity between them, it seems to him best to retain the 

 species above described. 



Prof. Peck secured enough material of the species to test it as to its 

 edibility, and includes it under the heading Edible Fungi, but does not 

 describe the edible qualities. 



Hypholoma Bonghtoni Pk. Rep., 1909: 23. Pileus fleshy, thin 

 except in the center, broadly convex or subhemispheric, rarely with a 

 slight umbo, glabrous or slightly fibrillose, often concentrically and 

 areolately cracking, pale reddish brown or grayish brown. Flesh 

 whitish, taste disagreeable. Lamellae unequal, moderately close, ad- 

 nate, purplish brown, seal brown or blackish, obscurely spotted, whitish 

 on the edge. Stem equal, floccosely fibrillose, striate at the top, hol-
