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 hearing long-necked antheridia: 

 the terminal branches with several short branchlets of a similar character. The smaller shorter append- 

 ages about the bases of (he larger ones, mostly dark purplish brown, with many beak-like cells. Peri- 

 thecia 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 perithecinm proper; the stalk-cell stout and elongate. IVritheeia 1S5-225 X 45-50 ft, the basal 

 cell 100 150 X 10 ji, the stalk-cells ISO .'500 /(. Receptacle about 150 /<. Appendage, longest 175, 

 longest basal cells 110 /;.

This species, which is nearly allied to T. in.sirjni.s, differs in its shorter and abundantly branched 

 appendages, as well as in the characters of its peritheeia, the basal cells of which are very large and not 

 related as in the last mentioned species.

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 suf- 

 fused 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 externally; and 

 terminally, as a rule, two large branches placed side by side (one of which may be wanting) sometimes 

 associated with one or two subterminal 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, how- 

 ever, 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 termi- 

 nations. The antheridia with long curved necks. Peritheeia usually several, brown, long and slender, 

 straight, very slightly inflated near the base, with a slight submedian enlargement; tapering throughout 

 to the short, truncate, well distinguished tip: the basal cells rather small, concolorous; the group narrower 

 than the stalk-cell and separated from it by a horizontal septum: the stalk-cell very large, usually elongate, 

 often inflated and thick walled. Spores about 50 X 4 ii. Peritheeia including basal cells 240-275 X 

 40 fi, the stalk-cell 150-325 X 25-35 /i. Appendages, longest 225 /<. Receptacle 100-185 X 14 (base) 

 X 55 (distal end). Total length to tip of perithecium largest, 800 /*.

The accompanying figures represent what appear to be variations of this species, fig. 12 being taken 

 as the Type, both obtained from the same individual. Although they differ as to the suffusion of the 

 receptacle, and to some extent as to the appendages, I am inclined to consider them the same, the differ- 

 ences, being perhaps due partly to difference in age or position of growth. 



RHADINOMYCES Thaxter. 



1 have called attention in my -Monograph to the close relation between this genus and Corethromyces, 

 but though 1 have been often tempted to unite them, 1 feel that until the species are more thoroughly 

 known they are best kept separate. The present genus normally produces one or more secondary peri- 

 theeia, while this is an exceptional occurrence in Corcthvomyces, and these secondary peritheeia always 

 arise from the subbasal cell like the primary one. In Corethromycrs, on the other hand, when a second- 

 ary perithecium occurs it is always developed from the basal cell of the appendage; and while this basal
