' Lactahius Calckolus: pileo tenui, centra depresso margine repando, 

 alutaceo, fusco, epidermide rimosa ; stipite curto, concolori ; lamellis perpaucis, 



distantibus, venoso-connexis, decurrentibis, albis. Pileus three inches across, 



thin, arched, so as to present a half ovate form, brown-buff, smooth, not viscid, 

 epidermis cracked ; flesh white ; stem short, half an inch in height and thick- 

 ness, brown-buff, like the pileus; gills white, decurrent, half an inch broad, 

 extremely distant, not exceeding twenty, more or less connected by transverse 



veins or plates, forked near the edge, exuding a mild milky juice. An 



extremely curious species, remarkable for its few distant gills, and the contrast 

 between the brown-buff stem and white gills. The pilei in all the specimens 

 found at present are laterally confluent. It cannot be confounded with any 

 known species.

 rufo; stipite gracili, brunneo, piloso, sursnm pallescente ; lamellis ventricosis,

umbilicate, membranaceous, red-brown, smooth, striate ; stem one and a half to 

 two inches high, slender, brown, closely velvety below, generally rooting, paler 

 above, more or less densely covered with short pale hairs and meal ; muce- 

 lium arachnoid white; gills white, at length pale, tan-colored, ventricose, 

 shortly adnate. Allied to Marasmius hcematoccpkalus 7nont. Two forms oc- 

 cur, the one smaller and more delicate than the oilier. 



3 Marasmius CLAVyEFOUMis : pileo, convexo, albo; stipite gracili, deorsum 

 attenuate, depresso- velutino, fusco, rursum albo, furfuraceo; lamellis carneo- 

 albris, antice latis, postice longe decurrentibus. Pileus two lines broad, con- 

 vex, tough, white ; stem one inch high, attenuated below, attached by a minute
