Dimeromyces Cryptici nov. sp. 



Male individual uniform pale yellowish, becoming faintly tinged 

 with brown. Receptacle and appendage forming an undifferentiated 

 axis somewhat divergent and tapering distally; the walls thick, the 

 transverse septa horizontal, the lower cells but slightly flattened. 

 Antheridia one to four, slightly divergent, the well developed stalk- 

 cell bent abruptly upward, the venter short and stout, the hyaline 

 neck straight, rather short, abruptly distinguished. Total length to 

 tip of appendage 70 X 9 /x. Antheridia 25 X 8 /z. 



Female individual like the male in general color and structure, 

 slightly darker. Subbasal cell of receptacle giving rise to a stout 

 slightly tapering secondary appendage, curved upward against the 

 perithecium and reaching about to its middle. Perithecia one or 

 several, the stalk short and bent upward, the rest subsymmetrically 

 fusiform, the tip hardly distinguished, the apex small, short, h\'aline, 

 abruptly distinguished by a slight constriction on both sides, that on 

 the inner subtended by a more or less well defined protrusion ; slightly 

 pointed distally with flat rounded lips on either side. Perithecia 

 75-84 X 18-22 ij.. Secondary appendage 75-90 X 9 /x. Total length

This small species is distinguished by its undifferentiated primary 



appendage, which is a direct continuation of the receptacle as in D. 



Thaxteri ]\Iaire, as well as by the single secondary appendage which is 



similar to and about as large as the combined receptacle and primary 



appendage, though less tapering distally. 



Dimeromyces Dhanyae nov. sp. 



Male individual dull pale olivaceous brown throughout. Recepta- 

 cle consisting of three very unequal and oblique cells, the basal ex- 

 tending upward anteriorly more than half its length: the appendage 

 consisting of three cells, the two basal concolorous, the second minute, 

 flat and horizontal, the terminal cell contrasting in form and color, 

 reddish brown, twice as long as broad, slightly constricted below a 

 terminal knob-like bluntly apiculate termination (cell?). Antheri- 

 dium appressed, the venter short, erect, the neck large, irregularly 

 bent in two directions, with a prominence on the inner side, distally
