purplish brown, tapering almost continuously from ike broad base; the 

 tip moderately well distinguished, the posterior lips prolonged to form 

 long nearly straight and horizontal Blightly inflated appendages which 

 project from the tip on either Bide : the anterior lips forming the truncate 

 \, which consists of two distinct lateral projections with an interven- 

 ing convex portion having a median apiculus. Perithecia about 85

Dichomyces biformis nov. <\>. 



Basal cell hyaline or nearly so, usually somewhat enlarged and often 

 with a heel-like anterior projection; lower tier rather narrow. < j u i te 

 opaque, the marginal cells extending up to the Bubterminal marginal cell 

 of the middle tier or to the eell next below it : the middle tier short and 

 stout, the nine to eleven cells hyaline or faintly reddish brown above, 

 usually becoming more or less sufluM-d below and externalh with brown : 

 the median cells, where suffused, marked by darker transverse flecks on 

 their anterior face, the marginal cells ending in a blunl distal often 

 hyaline prominence on either side: antheridia short and stout Bubconical, 

 subtended by a single brown inconspicuous appendage: the distal tier 

 assuming in well developed individuals the form of a rather slender 

 crescent, the number of cells very variable, the maximum about fifty, 

 sometimes less than half this number, in which case the form is stouter, 

 the marginal cells rarely extending above the tips of the perithecia which 

 are four to eight in number and of two kinds which are not known to be 



■ 



associated on the same individual : in the one case they are stouter. 

 purplish brown, the basal third or more often abruptly hyaline or nearly 

 so, the much darker red brown tip tapering rather abruptly to the apex, 

 which is hyaline nearly truncate, with a well defined median blunt pro- 

 jection; the posterior lip-cells prolonged much as in J), insignia to form 

 a long horizontal nearly cylindrical or slightly tapering bluntly tipped 

 hyaline appendage on either side ; the second type more often longer and 

 more Blender than the first, pale reddish brown, the tip tapering, Blightly 



truncate or blunt, often with a blunt median projection as in the first type, 

 but without appendages. Perithecia 105—110 x 20-oo ft. Receptacle
