as long as broad, its distal septum blackened; when simple, bearing a single branch, if divided, several- 
the basal cell of the outer branch usually rather short and somewhat suffused, commonly bearing two 
branchlets. The basal cell of the inner appendage usually smaller than that of the outer, sometimes 
equal, and like it simple or divided; when simple, bearing a branch on either side, or more if it is divided. 
All the branches of both appendages hyaline or nearly so, mostly once branched above their basal cells.

The typical unmodified form of this species is represented in fig. 5, a British specimen, which is taken 
8 the Type (B. M. No. 456); but the material examined shows very considerable variation similar to 
that which characterizes the "Clivina" group generally, and here usually manifests itself in abnormal 
divisions of cell IV, and of the basal cells of the appendages. Apart from other differences, the species 
is distinguished from others in this section by the black septum and suffusion which occur at the base of 
the outer branch of the outer appendage. It does not usually occur abundantly on a given host, but on 
the other hand does not appear to be uncommon. A form identical with this, or very closely allied was 
obtained on C. A uttrakuia Boh., from Luzon, Philippines in the Berlin Museum No. 885.

Perithedum large, pale yellowish or brownish becoming slightly tinged with amber-brown, often 
symmetrically inflated and tapering gradually to the tip, which is brownish below, becoming black on the 
inner ode, the lips subhyahne, turned slightly outward. Receptacle concolorous with the perithecium, 
normal except that cell V is greatly enlarged and extends upward covering nearly one half of the inner 
margin ot the pentheemm, bulging strongly outward and carrying out the insertion-cell, which is thus 
made lateral in position. Insertion-cell externally concave or indented. The outer appendage consisting 
ot a small roundish basal cell giving rise to two, rarely more, branches antero-posteriorly, which are usually 
once branched near the base, the branchlets very elongate, slender, attenuated, curved outward and 
Uo^nward: the inner appendage consisting of a similar basal cell from which arise usually two branches, 
one on either -side .similar to those of the outer appendage, the whole forming a hanging beard-like tuft.
