90. C. Petersii, B. & C. Pusillus ; pileo depresso sub- 

 zonato stipiteque gracili dealbatis; plicis distantibus decurren- 

 tibus ; interstitiis venosis. Curt. no. 6077. Amongst moss at 

 the base of trees, Alabama, Hon. J. M. Peters. 



Pileus 1 inch across, depressed, white, opake, with one or two 

 concentric furrows ; stem 1 inch high, 1 line thick, white like 

 the pileus ; folds moderately broad, distant, decurrent; inter- 

 stices wrinkled. 



Resembling somewhat the white variety of C. aurantiacus, but 

 a smaller plant, with broader folds. 



91. C. lignatilis, B. & C. Rufus ; pileo tenui iufundibuli- 

 formi striato glabra ; stipite subsequali plicis tenuibus decur- 

 rentibus. Curt. no. 1979. On rotten logs, South Carolina, 

 H. W. Ravenel. 



Reddish brown ; pileus 2 inches across, smooth, infundibuli- 

 form, deeply striate; stem 2 inches or more high, $-| inch 

 thick, smooth ; folds thin, decurrent. 



Of this we have no notes ; but the peculiar habitat and cha- 

 racters will distinguish it. 



92. C. Wrightii, B. & C. Pileo piano demum depresso, pal- 

 lide rubra ; stipite solido striato rufescente sursum incrassato ; 

 plicis demum decurrentibus glauco-rubris ; interstitiis venosis. 

 Curt. no. 5559. On the ground in the shade of trees, Connec- 

 ticut, C. Wright. 



Pileus h-\k inch across, plane, at length depressed, dull red, 

 edge irregularly deflexed; stem 1| inch high, 2 lines thick, 

 solid, striate, somewhat fibrous, brow r nish red, incrassated up- 

 wards ; folds at first free, at length decurrent, waved, of a pale 

 glaucous red j ( interstices veined ; spores fusiform, with the 

 endochrome retracted to either extremity, .> 2 \ inch long. 



Analogous to Agaricus laccatus. 



93. Marasmius velutipes, B. & C. Pileo umbilicato tenui 

 striato ocbraceo-fusco, 1. fusco; stipite striato velutino pallido, 

 1. basi ferrugineo ; lamellis angustis confertis adnexis. Curt,

 thin, dry, striate, umbilicate : stem l|-2 inches high, 1 line 

 thick, straight, clothed with pale velvety down, sometimes a little 

 tawny below, hollow r ; gills narrow, crowded, pale, slightly aduate. 



Differing materially from M. archyropus in the nature of the 

 clothing of the stem, and from M. spongiosus in the more 

 crowded narrow gills and umbilicate pileus. 



94. M. Olneii, B. & C. Pileo convexo glabra rufescente 

 striato ; stipite albo subtilitcr pulvcrulento-tomentoso insititio ;
