ACANTHOMYCES QrPOG^DS, nov. Sp. 



Peritheciura nearly sessile, terminal, pale straw-colored, hardly 

 inflated, continuing the sigmoid curve of the receptacle, its blunt 

 apex exceeding the tips of the appendages by about half its length. 

 Receptacle uniformly pale straw-colored, bent in a sigmoid curve, the 

 base slender, the remaining portion stout, the main axis consisting of 

 about eighteen superposed cells with very oblique septa. Ajjpen- 

 dages numerous, closely set, appressed, slightly curved inwards, deep 

 brown, the tips paler. Perithecium 145 X 37 ft. Appendages 110- 

 150 fi. Receptacle 340 X 37 fj..

ACANTHOMYCES FURCATUS, noV. Sp. 



Perithecium more or less suffused with brownish, straight, slightly 

 inflated at the base, tapering gradually to the apex, borne on a stout 

 stalk cell surmounted by several small basal cells. Receptacle more 

 or less tinged with brownish, its main axis consisting of about twelve 

 superposed cells, continued by a more slender prolongation beyond the 

 base of the perithecium, this prolongation sometimes forming a second 

 successive main axis terminated by a second perithecium and con- 

 tinued by a similar prolongation beyond the base of this second peri- 

 thecium which arises on the side of the general axis nearly opposite 

 to that which bears the first. Appendages dark brown, opaque, stout, 

 rigid, nearly straight or slightly curved outwards, the longest not 

 equalling the tip of the perithecium. Spores 48 X 4 /i. Perithecia 

 160-185 X 48-55 /x. Appendages (longest) about 150 /*. Total 

 length to tip of receptacle about 360 jx. Main body of receptacle 

 about 220 /u long. Total length when two perithecia present (longest) 

 550-600 ^.

ACANTHOMYCES BREVIPES, nOV. Sp. 



Perithecium suffused with reddish brown, subfusiform with a well 

 developed stout stalk. Receptacle very short, the main axis consist- 

 ing usually of five superposed cells, with a short prolongation beyond 

 the base of the perithecium, normally of not more than three or four 

 cells, the cells all pale yellowish or with brown suff'usions, the septa 

 in all cases usually hyaline. Appendages few in number, opaque or 

 nearly so, scattered, some of them very long, curved, and greatly ex-
