Nearly hyaline except the brown or smoke-colored perithccinm and sub-basal cell of the 
rccci>tac]e. Perlthecium large, inflated towards the base, the narrower distal half abi-ui>tly 
rounded and contracted below a rather narrow apex with protruding lips bent outward ; general 
color dark brown, much deeper below the apex. Appendages numerous, crowded, slender, short, 
the lower segments inflated, arising as in L. Guerinii. Receptacle elongate, consisting of a short 
curved stout nearly hyaline basal cell, a Tery long sub-cylindrical sub-basal cell, smoky brown in 
color, with deeper brovvn wart-like or scale-like scattered prominences of varying size, the re- 
maining cells normal except that tlie insertion-cells of the appendages are irregularly divided.
