316 DECADES OF FUNGI. 
Pileus 3 inches across, thin, arched so as to present a 
half-ovate form, brown-buff, smooth, not viscid ; epidermis 
cracked, flesh white. 
Stem short, } an inch in height and thickness, brown-buff, 
like the pileus. Gills white, decurrent, 1 an inch broad, sexs 
tremely distant, 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 them and the brown: 
buff stem. The pilei in all the specimens found at present 
are laterally confluent. It cannot be confounded with any - 
known species.
