secondary branches and an antheridium; the branchlets proliferous and forming an axis of usually llim 
cells, the lower bearing an antheridium, and each of the two upper an antheridium and a perithelium; 
there being thus sixteen antheridia and eight perithecia in fully and .symmetrically developed speeimen 
which form a dense, spreading, fan-like tuft, the antheridia being in general poslerior in position, over- 
lapping one another between the black sterile appendage and the perithecia. Antheridium distalh 
broadened and truncate, elongate; the stalk-cells about equal and about one half the length of the bod 
of the antheridium or somewhat longer than this; the cells of the second tier somewhat unequal ; the cells 
of the third tier smallest; the terminal cells prominently rounded distally, the appendiculate cells usualh 
prominent, forming papillae which are subtended by the appendages, all four of which do not always de- 
velop; these appendages relatively short, two to three-septate, tapering to a blunt point, distinctly inflated 
above the slightly constricted base. Perithecium relatively large, straight or slightly curved. Bomewhal 
inflated below, tapering gradually to the rather short, moderately well distinguished tip; the apex hluutl; 
rounded, the basal cells relatively small; the stalk-cell variably developed, its distal end usually somewhat 
broader than the basal cells collectively, sometimes more than half as long as the body <>f the perithecium.
