profhiced spores. The species seems well distinguished by its broad 

 siibgaleate apex, slender and well developed perithecial stalk-cell, 

 and its long appendage. 



Corethromyces Medonis nov. sp. 



Receptacle geniculate between the basal and subbasal cells, the 

 former squarish or slightly broader than long, quite hyaline; the latter 

 opaque, broader distally, sometimes twice as long as broad, indistin- 

 guishable from the main appendage with which it is continuous. The 

 primary appendage hyaline along the inner margin, otherwise nearly 

 opaque, the subdistal and much smaller distal cells giving rise to a 

 group of hyaline branches which are rather short, once or twice 

 branched, directed inward; some of the branchlets consisting of 

 seriate antheridia of the normal type. Perithecium hyaline, becom- 

 ing yellowish; the hyaline stalk-cell well developed, narrower below, 

 the outline from its base to the apex of the perithecium almost sym- 

 metrically fusiform; body of the perithecium slightly inflated, the 

 outline of the margins somewhat undulate; the tip not distinguished, 

 often slightly bent outward, the apex bluntly rounded. Perithecium 

 78-100 X 20-28 m; the stalk-cell 20-39 X 12-16 /x. Primary appen- 

 dage 27-31 X 9 /x, its longest branches 50 /x. Total length to tip of 

 perithecium 125-175 /x.

 Java. On Mcdon Binnanus Fauv., No. 2368, Borneo. 



A small species more nearly allied to C. purpurasccns than to other 

 described species, and belonging to the Cryptohium-mhdihitmg group. 



Corethromyces decipiens nov. sp. 



Receptacle becoming almost wholly opaque, a small hyaline point 

 just above the foot, the basal cell small, geniculate, prolonged poste- 

 riorly and distally to form an opaque, free, somewhat divergent, 

 spur-like upgrowth, spoon-shaped or of nearly equal diameter through- 

 out, blunt-tipped; its base united throughout to the long flat distally 

 hyaline otherwise deeply suffused subbasal cell; its remaining free 

 portion lying beside the hyaline appendage, the branches of which 

 reach some distance beyond its extremity. Appendage arising in the 

 angle between the base of the perithecium and the black spur-like
