NEW INDO-MALAYAN LABOULBENIALES. 33 



producing antheridia; the cells of the lower decidedly larger than 

 those of the upper; the terminal pair closely associated to form an 

 evenly rounded termination, in the types without appendages of any 

 kind. Perithecia short and stout, pale straw-colored with a slight 

 smoky tinge; the stalk-cell short, broader distally, somewhat longer 

 than broad ; the body asymmetrical, one margin straight and ending 

 in a tooth-like, brown, erect and slightly cur^■ed appendage at the tip; 

 the other slightly and broadly convex, and abruptly indented below 

 the small hyaline broadly rounded apex formed by the other lip-cells, 

 which are slightly exceeded by the tooth-like appendage. Perithecia 

 125-134 X 40 IX, "the stalk-cell 40-45 m- The tooth-like process IS X 

 10 fx at base. Antheridia 65 X 24 ix. Primary appendage 24 X 12 ix. 

 Receptacle, exclusi^■e of foot, about 24 n. Total length to tip of peri- 

 thecium 215 ix, including foot.

But three specimens of this small species have been examined, one 

 of which is immature, while the others are well developed and in good 

 condition. Each bears a single perithecium only, but it is probable 

 that more may be formed. The form is clearly distinguished from 

 all others known by the tooth-like appendage at the tip of its perithe- 

 cium. It is possible that the antheridia may in some cases be appen- 

 diculate, but there is no indication in the types that such is the case. 



Herpomyces Panesthiae nov. sp. 



Male indicidual. Receptacle consisting of four superposed cells, the 

 basal much larger and longer and distally inflated; the rest subequal; 

 all, or only the two terminal ones bearing antheridia directly, or single 

 cells from which antheridia arise distally: the antheridia twelve or 

 more, of the usual type ; the group broad below, the necks more or less 

 appressed. Receptacle SO /x, its basal cell 40 X 20 fx. Antheridia 

 60 fx. Total length to tip of antheridia about 150 /x. 



FcmaJc indiindual. Hyaline. Primary receptacle minute, the basal 

 cell more elongate, narrow below, the rest subequal, the terminal one 

 nearly circular in outline, except its base, and terminated by a bhuit 

 apiculus; the subbasal cell gi^'ing rise to two secondary receptacles 

 each of which produces a single perithecium on either side of the pri- 

 mary receptacle. Secondary receptacle rather strongly curved, distally 

 broader, the cells vertically elongated, one of them, the largest, extend-
