 de Chiriqui, Panama. Sharp Collection, No. 1157. 



Sphaleroniyces Indicus now sp. 



Perithecium relatively very long and large, yellowish, very slightly 

 inflated toward the base, tapering very gradually to the broad, blunt tip 

 which is subtended by a truncate, conical lateral projection ; the stalk- 

 cell relatively short. Receptacle relatively small, the two cells nearly 

 equal, the upper bearing the stalk-cell of the perithecium terminally and 

 the basal cell of the appendage laterally ; the latter overlapping it to its 

 base. Appendage consisting of four superposed cells, the basal (stalk- 

 cell) small, triangular ; the two cells above it larger and longer, bearing 

 short antheridial branches from the upper inner angles ; the terminal 

 cell smaller, subcorneal, bearing a small terminal branchlet. Spores 

 about 44 X 4 /a. Perithecium 290-340 X 45 ft, the stalk-cell 72 /x. 

 Receptacle 55^. The appendage 125 /a.

Corethromyces Latonae nov. sp. 



Perithecium reddish brown with a purplish tinge, often straight, or 

 externally concave, slightly inflated ; the lip-cells forming a small short, 

 slightly bent, nearly cylindrical, truncate, or papillate terminal projection, 

 which is rather abruptly distinguished ; the secondary stalk-cell, and the 

 basal cell above it, bulging outward more or less prominently, and 

 separated by a rather conspicuous irregular indentation : the stalk-cell 

 small and squarish. The basal cell of the receptacle asymmetrical ; its 

 anterior margin straight and perpendicular, the posterior slightly curved 

 and oblique ; its distal margin oblique with a posterior protrusion ; its 

 slender base translucent, but otherwise opaque, the opacity involving a 

 portion of the small flattened subtriangular subbasal cell. The appendage 

 consisting of a series of about five successively smaller hyaline cells, the 

 lowest greatly flattened ; the series above, the distal cells of which soon 

 disappear, often turned outward so as to become almost horizontal in 

 position, giving rise from their inner sides to numerous hyaline branches, 

 which may be more or less copiously branched. Spores about 35 X 2 fx. 

 Perithecium 90-105 X 20-25 ^, the stalk and basal cells together 20-
