Rhizornyces crispatus nov. sp. 



Perithecia brownish, rather stout: when viewed Bidewise, the inner 

 margin strongly convex, the outer nearly Btraight with a general median 

 elevation or concave owing to a general outward curvature, tapering to 

 the undifferentiated tip, tin- apex broad truncate usually symmetrically 

 bisulcate : viewed at right angles to this position Btraight symmetrical, 

 abruptly enlarged helow the narrow symmetrical abruptly distinguished 

 tip: the basal cells well defined nearly isodiametric, the stalk-cell la' 

 as long or longer than the perithecium. Receptacle two-celled, the foot 

 typically modified and blackened without rhizoids, distally geniculate 

 through a protrusion of the distal cell helow the insertion of the stalk- 

 cell and Opposite that of the appendage. Appendage end. sometimes 

 exceeding the tip of the perithecium, consisting of a single series of super- 

 posed cells, the three or four lower suffused with smoky brown, the rest 

 subhyaline, each cell except the basal one giving ri.-e directly and exter- 

 nally to a branch, the insertion in successive cells being .somewhat to the 

 right and left of the median line so as to form two vertical rows, the 

 basal cells of alternate branches being superposed ; each branch con- 

 sisting of a basal cell externally blackened, which gives rise above to a 

 -celled short branchlet, bearing usually a pair of long, Blender anthe- 

 ridia, the remainder of the branch curved upward blackish brown except 

 its upper margin, and giving rise from its lower (external) Bide to a series 

 of close-set simple branchleta, black, recurved, more abruptly at the tips 

 which are slightly enlarged and nearly hyaline, the whole suggesting the 

 margin of a curled black feather. Spores 20 X 2.8/*. Perithecia 65- 

 75 ■ -~ 80/*, the stalk-cell 50-85/*. Receptacle 80/*, Append. i«
