Teratomyces petiolatus nov. sp. 



Receptacle nearly symmetrical, almost wholly black, slender below, 

 expanding rather abruptly distally ; the appendiculate cells relatively 

 large and long, translucent, brownish yellow, subtended by a slight en- 

 largement. Appendages numerous, spreading, the larger ones consisting 

 of a very large colorless or brownish basal cell, which bears a series of 

 branchlets externally and several branches terminally ; the branchlets 

 usually short, and two-celled, the distal cell usually long, beak-like and 

 clear purplish brown, the lower cell hyaline or light brown and in the 

 lower branchlets usually bearing long-necked antheridia: the terminal 

 branches with several short branchlets of a similar character. The 

 smaller shorter appendages about the bases of the larger ones, mostly 

 dark purplish brown, with many beak-like cells. Perithecia usually 

 several, large, symmetrical, purplish brown ; the tip short, rather narrow 

 and abruptly distinguished ; the basal cells relatively very large, forming 

 a portion of the stalk sometimes half as long as the perithecium proper ; 

 the stalk-cell stout and elongate. Perithecia 185-225 X 45-50 /a, the 

 basal cell 100-150 X 10 fx., the stalk-cells 180-300 yu,. Receptacle about 

 150 [M. Appendage, longest 175, longest basal cells 110 /a.

Teratoniyces insignis nov. sp. 



Receptacle usually quite opaque, long, slender ; the outline unbroken 

 and nearly straight, tapering evenly to the slightly geniculate base, which 

 is nearly hyaline just above the foot: the margin of the suffused area 

 distally strongly oblique, especially before maturity ; the appendiculate 

 cells small, becoming brownish. The appendages numerous, spreading, 

 the larger ones hyaline or nearly so, consisting of a large elongate basal 

 cell, which bears two or three small remote antheridial branches exter- 

 nally ; and terminally, as a rule, two large branches placed side by side 

 (one of which may be wanting) sometimes associated with one or two sub- 

 terminal smaller branchlets, the basal cells of which are dark contrasting 

 brown : the terminal branches hyaline with branchlets like those of the 

 basal cell ; the branchlets, however, more numerous, contrasting, brown, 

 simple or branched, many having characteristic beak-like terminations, 

 while others are blunt tipped, with oblique septa. The smaller peripheral 

 appendages more or less crowded around the bases of the larger ones, 

 with conspicuous and numerous beak-like terminations. The antheridia 

 with long curved necks. Perithecia usually several, brown, long and
