NEW LABOULBENIALES. 705 



broader than the inner and pointed, the inner narrower distally, but 

 truncate, the apex thus having a very different appearance from 

 different points of view. Spores about 45 X 3.5 /x- Perithecia 

 85-110 X 24-30 M, its apex 22 X 20-18 X 25 ^i. Appendage, to tip 

 of terminal antheridium, 35-40 n, the antheridia about 18 n. Re- 

 ceptacle 20-25 X 10-12 fx. Total length to tip of perithecium 120- 



140 m. 



On the elytra of minute species of Coccinellidae: No. 2560 (Type) 

 and 2059, Grenada (Brues); Nos. 1706, Mandeville, 1736 and 1752 

 Balaclava, Jamaica, W. I.; No. 2384, Mindanao, P. I.; No. 2175, 

 Sarawak, Borneo. 



The material of this species from Borneo and the Philippines varies 

 somewhat from the West Indian type, the terminal cell of the append- 

 age usually bearing two paired antheridia, while each cell above the 

 basal may bear a single one. The projections formed by the lip-cells 

 in this material are also relatively shorter and more blunt, but are 

 otherwise entirely similar. In the type, and in No. 1706, all the 

 appendages bear only two antheridia, but in the other West Indian 

 specimens a third or fourth also arises from the subterminal cell, and 

 the cell below it, in almost all the individuals examined. The species 

 seems to be a rare one, and is not often found in a fully matured 

 condition. 



Stigmatomyces virescens, to which this species is most nearly allied, 

 seems also to be widely distributed, and has been obtained from 

 Brazil, Hayti, Jamaica and Sarawak, Borneo; individuals from the 

 latter locality agreeing in all respects with the type. 



Ilytheomyces nov. gen. 



Receptacle compact, two celled, the foot and basal cell usually 

 indistinguishable ; the subbasal cell bearing the stalk-cell of the peri- 

 thecium terminally and the appendage laterally. Appendage con- 

 sisting of an axis of superposed cells indeterminate in number, the 

 subbasal cell cutting off a small androphorous cell distally on the 

 inner side, which produces typically two large, simple, colored, 

 paired antheridia, one of which may be lacking or may be replaced 

 by, or associated with, a sterile branchlet: the terminal cells of the 

 axis, all those, as a rule, above the subbasal cell, giving rise to variously 

 complicated and modified branches, usually from both the inner and 

 outer sides. Perithecium normal, the basal and stalk-cell region well
