Amorphomyces floridanus, nov. sp. 



Male unknown. 



Female. Receptacle consisting of a basal cell, partly divided, from 

 which arises on one side (corresponding to the ascigerous side of the 

 perithecium) a somewhat indurated projection which extends upwards 

 nearly to the base of the perithecium. Perithecium externally rounded 

 and tapering considerably to the blunt apex, the basal cells, one of 

 which is as large as the rest of the receptacle, forming a short stalk. 

 Spores about 30 X 5 /». Perithecium 150 X 52 p. Receptacle (in- 

 cluding stalk cells of perithecium) 02 /x long. 



On the abdomen of Bledius basalts Lee, Florida. 



HAPLOMYCES, nov. gen. 



Receptacle consisting of two small superposed cells from which 

 arise the single perithecium and the single antheridial appendage. 

 Perithecium large, pointed, borne on a single stalk cell surmounted by 

 two basal cells. Antheridial appendage consisting of a basal cell sur- 

 mounted by a terminal body, the antheridium, divided by anastomos- 

 ing septa into numerous small cells and furnished with a short lateral 

 projection, together with a subterminal short spine-like process arising 

 from a rounded base. Asci four-spored, arising from four main asco- 

 genic centres, each of which is divided into two secondary centres. 



A very simple type, without sterile appendages, nearly allied to 

 Cantharomyces by the presence of a highly developed cellular anthe- 

 ridium, which in the latter genus is lateral in position and without the 

 characteristic thorn-like tip. The three species described adhere 

 strictly to the generic characters given, and appear to be abundantly 

 distinct. 



Haplomyces californicus, nov. sp. 



Perithecium faintly olive-brown, inflated at the base ; the distal 

 portion curved strongly inwards, the stalk cell hyaline, broad, sub- 

 triangular ; the basal cells short and broad, the inner larger, its pointed 

 apex extending upwards beyond the ascogenic centre, both more 

 or less suffused with olive-brown. Receptacle small, the basal cell 

 slightly suffused, the distal cell black and opaque, the opacity in- 

 cluding the whole of the basal cell of the appendage. Autheridium 

 twice as long as broad, tinged with brown. Thorn-like apiculus 

 prominent, its base well marked. Spores 37-40 x3i». Penthecia 

 1:30-145 X 65 ju- Stalk cell of perithecium 45-50 x 38 n. Anthe-
