ceptacle variable, minutely punctate, pale amber-brown or amber-yellow, gradually tapering from the

is mostly free. Outer appendage consisting of a series of about seven to ten obliquely superposed cells, 
each bearing distaUy and externally a single simple branch; the branches constricted at the first, second, 
and turd septa, which are deeply blackened; the second less conspicuously, the basal and subbasal cells 
variably suffused with clear brown especially near the septa, the distal portion of the branch hyaline, 
tapering, somewhat inflated above its usually brown base: inner appendage consisting of a basal cell 
which gives rise on either side to a branch resembling the outer appendage, often with fewer cells (some- 
femes only 3-ce led) amdarly branched, except that the lower branch consists of a single cell which bears
