51. Receptacle appearing to be distally multicellular through proliferation, 
the resultant cells more or less copiously appendiculate. 
52. A primary appendage of superposed cells bearing specialized antheri- 
dial branchlets superposed externally, similar branches arising 
from cells on one side, about the bases of the perithecial stalk- Idiomycetese

cells. 
53. No primary appendage distinguishable at maturity. 
54. Receptacle obconical, the proliferous cells producing distally a dense 
tuft of appendages enveloping the bases of the perithecial stalk- 
cells. 
55. Sterile branches few, antheridial cells intercalary in continuous 
series. 
56. Sterile branches and branchlets copious, antheridial cells free, ex-

appendages and associated with beak-like sterile cells. 
57. Receptacle subtriangular, flattened, with paired, two-celled rounded 
outgrowths and paired perithecia, proliferating cells above their 
bases producing numerous branched appendages. 
Receptacle consisting of two superposed cells, the upper giving rise 
directly to a more or less well distinguished free main appendage 
and to one or more free, stalked perithecia. 
Antheridial branches producing serial intercalary antheridia. 
Primary appendage hyaline producing branches from its basal cell, 
secondary perithecia originating like the primary. 
Primary appendage more or less blackened, its basal cell producing 
secondary perithecia when these occur. 
Antheridia borne free, singly, or in groups, on the appendage, or on its 
branches. 
Main axis of the appendage consisting of two superposed cells, the 
upper bearing a series of branches from the bases of which arise 
branchlets bearing the antheridia singly or in groups 
64. Appendage consisting of several superposed cells, the distal bearing 
sterile branches, the basal often perithecia, the rest short antheridial 
branchlets from their upper inner angles.
