This species is subject to considerable variations the extremes of which arc illustrated in figs. 1 3, 
the latter being the normal type-form from which the original description WBI drawn. Thi normal 
form, although it is not distinguished by any very striking peculiarities, docs not sec. nearlj ■ lated Io 
any of the known species. The normal arrangement of the branch, of its ontcr appendages is unusual, 
cell IV is relatively small, not longer than cell V in general; the rest of the receptacle slender, the peri. 
.Iiccium relatively small, as are the spores. Between this normal type and the variety represented m 
fig. 2, a complete series of intermediate conditions occurs. The variety represented in I.. 1, in which 
the general form is stouter and more compact, with a relatively larger peritheeium, havmg a tip quit, 
differently shaped, was found in company with the type and is certainly not to he separated from u. It 
spores are larger (45 X 4.5 fi), however, than in the type, in which they hardly exceed 3., n m length.
