160 PROCEEDINGS OF THE AMERICAN ACADEMY. 



Appendages concolorous with the receptacle, the outer simple, straight, 

 rigid, mostly somewhat divergent; the inner consisting of a basal cell 

 often as large as that of the outer, and giviog rise on either side 

 distally to a branch similar to the outer appendage which bears several 

 lateral antheridia near the base. Perithecium (including outgrowth 18 /x) 

 185-190 X 33-37 /x. Total length to tip of perithecium 375-450 /x; 

 to insertion-cell 185-300 fx ; greatest width about 48 /t. Appendages, 

 150 /x. 



On Catascopus? sp., Brit. Mus. No. 663, Assam, India. Inferior 

 surface. 



Laboulbenia barbata nov. sp. 



Perithecium 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 side, the 

 lips subhyaline, 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 of the 

 perithecium, bulging strongly outward and carrying out the insertion- 

 cell which is thus made lateral in position. Insertion-cell externally con- 

 cave or indented. The outer appendage consisting of 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 downward : 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. Perithecia 190-200 X 55-60 /t. 

 Total length to tip of perithecium, average 400 ^ ; to insertion-cell, aver- 

 age 1 90-200 jM. Appendages, longest 450-650 |U. Spores 100 X 6 ^.

Laboulbenia bicornis nov. sp. 



Perithecium wholly free, dark brown tinged with olive becoming 

 opaque, lighter at the base ; very elongate, nearly straight, slightly and 

 gradually inflated from the neck-like base to about the middle, thence 

 tapering very slightly to the tip, which is distinctly though not abruptly 

 differentiated : the two inner lip-cells symmetrical each terminating in a 

 small rounded prominence which bears a second smaller rounded terminal
