32 THAXTER. 



growing in opposite directions, sometimes more; usually consisting 

 of a single cell somewhat longer than broad, distally pointed, and 

 bearing the antheridium and perithecium which diverge right and left 

 at nearly a right angle. Stalk-cell of perithecium very elongate, 

 abruptly distinguished by a slight distal enlargement from the basal 

 cell-region, which is also relatively very large and long, and slightly 

 broader distally than the venter of the relatively small perithecium 

 which is hardly inflated and not distinguished from the usually curved 

 rather elongate distal portion which tapers slightly to the l)lunt apex; 

 the tip hardly or not at all distinguished. Stalk-cells of the antheri- 

 dium relatively very long, (each al)out eight or nine times as long as 

 broad), the basal pair broader distally and, abruptly distinguished from 

 the narrower base of the second pair which is shorter and also distinctly 

 broader distally; abruptly distinguished from the two pairs above, 

 the cells of the upper smaller and separated from the lower by a distinct 

 constriction, bearing directly two terminal appenflages, one usually 

 longer than the other, sometimes only one, without evident basal cells 

 in some instances. Perithecium: stalk-cell 156-275 X 20 /i; basal 

 cell-region 55-65 X 20-28 /x; main body 118 X 20-25 m- Spores 30 X 

 4 M- Antheridia 62-82 X 18-20 m- Receptacle 32 m- Primary ap- 

 pendage 125-175 X 10-15 /i. Antheridial appendages 40-150X8^1. 



On the inferior abdomen and thorax of Amaurodvra Kraepclini 

 Fauv. No. 2078, Samarang, Java. 



A species well distinguished by its peculiar long-stalked perithecium, 

 with highly developed basal cells, and its simple primary appendages, 

 as well as by its unusually elongate antheridial appendages. 



Monoicomyces denticulatus nov. sp. 



Basal cell hyaline slightly narrower distally, somewhat broader than 

 long; subbasal cell hyaline much smaller, bearing distally the some- 

 what divergent primary appendage which is distinguished by a black- 

 ish brown septum and consists of a single cell, nearly twice as long as 

 broad, stout, distally rounded and externally rather deeply suffused 

 with blackish brown. Fertile branches two; consisting of single 

 more or less deeply suffused cells, which arise on either side of the sub- 

 basal cell, and bear single antheridia and perithecia. Antheridial 

 appendages symmetrically paired, slightly smoky, their stalk-cells 

 hardly distinguishable from the basal cells, deeply suffused externally, 

 nearly twice as long as broad, the two pairs above much smaller, both
