NEW INDO-MALAYAN LABOULBENIALES. 11 



on the inner side, the distal portion contracted abruptly to form a 

 characteristic rostrate termination almost twice as long as the venter, 

 I^urplish brown, lighter and slightly constricted above the middle; 

 the apex blunt, often slightly bent. Spores 20 X 7.5 m- Venter of 

 perithecium, exclusive of marginal cells of axis, 42-48 X 25-28 ^u ; 

 the rostrate termination 63-72 X 10-12 ix. Secondary appendages 

 24 X 3.5 fjL, not including their projecting basal cells which are 7-12 X 

 2.5 M- Total length to tip of perithecium 240-450 X 20-35 /jl. 



On the right elytron of Taniignathus ruficoUis Kr., Java, and Sara- 

 wak, Borneo. 



This species of which the specimens from Borneo are taken as the 

 types, the Ja^'an material being immature, is aberrant in several re- 

 spects; more especially in its rostrate perithecium with inflated venter 

 and laterally placed ascogenic cells. The secondary appendages sug- 

 gest those of Monoicomyces Lcptochiri in the general appearance of 

 their dark projecting basal cells. Although a large species, it is not 

 readily seen, since it lies perfectly flat on the elytron. 



Rickia Tomari nov. sp. 



Form rather short and stout, foot small, structure determinate or 

 subdeterminate, nearly hyaline, except the deep brown hyaline-tipped 

 perithecium. Basal cell somewhat longer than broad, slightly in- 

 truded between, or broadly rounded and slightly overlapping a pair of 

 subbasal, nearly equal, somewhat irregular cells above which three 

 cell-rows are distinguished: an axial row of three larger and somewhat 

 dissimilar cells, followed by three or two successively smaller cells 

 which lie in contact with the base of the perithecium on the posterior 

 side : a posterior row of usually six more regular and somewhat rounded 

 cells, the upper two or three small and extending to or nearly to, the 

 end of the axial series, terminating in the flattened basal cell of the 

 primary appendage; all its cells except the uppermost, cutting oft' 

 three or four small cells which lie side by side somewhat irregularly 

 and horizontally, each giving rise to well developed antheridia of the 

 normal type, or to short appendages, smaller than the antheridia and 

 much more numerous, both distinguished by dark brown cup-like 

 suffusions at the hardly constricted subtending septa: the anterior 

 row consisting of usually six marginal cells, the two terminal ones 

 lying beside and united to the base of the perithecium, and extending 

 higher up than the corresponding cells of the axial row on the opposite
