Cantharomyces Blidii nov. sp. 



Color yellowish. Perithecia subconical, one or more in num'ber, 

 each borne at the summit of a division of the receptacle arising from the 

 supra-basal cell. Pseudoparaphyses one, rarely more, arising from the 

 supra-basal cell : composed of three superposed basal cells, the second 

 swollen, longitudinally septate ; the third squarish, small, surmounted 

 by one or two small cells, from which arise a variable number of 

 slightly curved, septate, slender branches themselves variably once or 

 twice branched. Receptacle simple or compound ; the basal and sub- 

 basal cells rather short, the lower and outer portions of the wall of 

 the latter often thickened, deep black, and indented ; but sometimes 

 without signs of this modification. The supra-basal cell may give rise 

 to one or more divisions of the receptacle, which are sub-lateral in 

 position, and consist of a long, cylindrical basal cell, surmounted by a 

 broader short cell, divided longitudinally by a median septum, and 

 bearing the perithecium directly. Spores slender, fusiform, involved 

 in mucus, asymmetrically once septate, 25 X 3.5 /n. Perithecia 92.5- 

 130 IX X 33-55 fi, average 114 X 42 fi. Pseudoparaphyses, total 

 length 90-180 ^i, average 150 fi. Total length to tip of perithecia 

 200-370 /i, average 280 fi. 



On Blidius assimilis. Champaign, III. (S. A. Forbes). 



I am greatly indebted to the kindness of Professor Forbes for speci- 

 mens of the two singular forms above described. The material of 

 C. verticillata consisted of but four adult specimens, so that further 

 study may show the presence of a compound receptacle in this species 

 as well as in G. Blidii, where it was observed in only a few of the 

 twenty or more individuals examined. The secondary pseudopara- 

 physis of C. verticillata is wholly wanting in C. Blidii. 



LABOULBENIA Montagne et Robin (1853). 



Laboulbenia elongata nov. sp. 



Color brown or blackish. Perithecium long-ovoid, darker just be- 

 low its hyaline apical pore. Pseudoparaphyses arising from a black 

 basal disk ; two in number, brown to blackish, sometimes hyaline near 

 their extremities, septate, slightly constricted at the septae ; their basal 

 cells distinct, the inner giving rise immediately to two branches which 

 may be either simple or once or twice dichotomously branched. The 

 outer pseudoparaphysis usually once or twice dichotomously branched
