any reasonable doubt the vexed question as to the presence of sexuality in the higher fungi. The 
immediate relation of the present to other genera, with the exception of Dimeromyces, is not 
clear ; yet it seems probable that among described forms the species of Dichomyces and Pey- 
ritschiclla a[)proach it more nearly than any others. In both of these instances the same ten- 
dency towards a bilateral development is combined with a close correspondence in the sexual 
organs.

Male tndivUJ^f'rl. Receptacle of four superposed cells, the distal one tapering upward, and 
tonninated hy a more or less distinctly marked, usually slightly blackish, knob. Anthcridium 
arising from the sub-basal cell and partly united to the sub-terminal cell of the receptacle; ex- 
ternally nearly straight, bulging internally ; its main body about as long as the usually straight 
terminal neck, the base of which is distinctly inflated to form the cavity into which arc dis- 
charged the antlicrozuids. Total length to tip of receptacle, 40/i; to tip of anthcridium, 50- 
55/x. Greatest width, 14/^. 
Female individual Sterile portion of the receptacle consisting' of a large sub-terminal and 
much smaller nearly spherical terminal cell, the main portion consisting of two superposed 
cclLs forming a more or less three-sided body, the perithecia and sterile appendages arising in 
the manner characteristic of the genus. Perithecia slightly inflated, rather abruptly contracted 
to form the stalk portion; the tip oblique ; one of the lip-cells projecting as a short but distinct 
tooth-hke prominence ; while just below this prominence a conspicuous tooth-like outgrowth 
arises from one of the anterior sub-terminal wall-cells, and extends obliquelv upward and out- 
ward more than half its length beyond the tip of the perithecium. The st'alk of the perithe-
