ridium 33 X 19 p.. Receptacle 45-55 X 15-13 p. Total length to 

 tip of perithecium 240-260 /x. Total length of antheridial appendage 

 48-55 (i. 



On abdomen of Bledius ornatus Lee, California. 



Hapeomyces texanus, nov. sp. 



Perithecia almost symmetrically conical, straw-yellow, the tip rather 

 blunt; the stalk cell nearly hyaline, twice as long as broad, slender at 

 the base ; the basal cells elongate, nearly equal ; distally almost trun- 

 cate. Receptacle small, the basal cell nearly hyaline ; the distal cell 

 very small, slightly broader than long, blackened and opaque, the 

 opacity including the lower outer portion of the basal cell of the 

 appendage, the unblackened portion of which, together with the an- 

 theridium, becomes suffused with brown. Spores 40-45 X 3.7 p. 

 Perithecia 165-185 X 50-55 p. Stalk cell of perithecium 65-90 

 X 26-33 p. Antheridium 32 X 18 /*. Receptacle 37-45 X 18 /*. 

 Total length to tip of perithecium 315-370 /*. Total length of 

 antheridial appendage 35-40 p. 



On abdomen and elytra of Bledius rubiginosus Er., Texas. 



Distinguished from the preceding species by its pale yellowish color, 

 conical nearly straight perithecium, and by the elongated basal cells 

 of the latter. What appears to be the young condition of the same 

 species occurred with it, differing in the absence of any blackening 

 of the receptacle or appendage. 



Haplomyces virginianus, nov. sp. 



Perithecium short, stout, straw-yellow, outwardly inflated, the outer 

 margin curved strongly inwards to the conical distal portion, the apex 

 bluntly pointed; stalk cell long, nearly cylindrical, distally expanded 

 slightly, the basal cells of perithecium very small, almost obsolete. 

 Basal cell of receptacle large, the distal cell very small, and several 

 times as broad as long, the stalk cell of the perithecium arising from 

 it, but also connected with the distal portion of the basal cell. Basal 

 cell of antheridial appendage squarish, slightly broader than long, the 

 antheridium rounded, its reticulations coarse, the thorn-like apiculus 

 very fine (about 5 n long) and abruptly distinguished from its flat- 

 tened base. Spores 33 X 3.7-5.5 M . Perithecia 110-130 X 55-60 p. 

 Stalk cell of perithecium 75-110 X 19-25 p.. Antheridium 18 p long. 

 22-23 fi wide. Receptacle, basal cell 45-50 X 18-19 /*, distal cell 

 about 18.5 X 6 /x. Total length to tip of perithecium 220-275 /x. 

 Total length of appendage 30-33 p.
