Segments をげ e linear-ciirieate, almost cylindrical, ]i(；re and there very

Cystocarps are collected in terminal segments, which are often some- 
what separated from lower り ortiou by cons れ iction. They form an ob- 
long subnematbeciose aggrega む on ou both surfaces， opening afterwai.d 
by a carpostom ; uiicleus lodged in a cavity beneath the ccn'tic;il layer, 
simple, globular, surrounded by the circumniiclear filamen わ ， at the 
base of whic じ a placental cell is situated, from which radiates a mass 
of spores. ‘ 
Tetraspores also form an oblong soriis on both surfaces of ultimate 
segnients leaving marginal portion sterile ； they are oblong, cruciate ， 
immersed among the cortical filaments.
