THAXTER. — NEW LABOULBENIACEiE. 437 



basal and subbasal cells relatively large, hyaline, the rest pale straw 

 colored, the main axis consisting of fifteen or sixteen cells, the upper 

 five or six forming a free erect termination. The appendages not 

 numerous, appressed, brown ; those about the base of the perithecium 

 larger, distally blunt and hyaline, about two thirds as long as the peri- 

 thecium. Perithecia 90-130 X 27-30 //.. Receptacle 175-225 fx. Ap- 

 pendages, longest, about 100 fx. Total length to tip of perithecium 250- 

 325 fx..

Rhachomyces tenuis nov. sp. 



Perithecium relatively small, the lower half or more hidden by the 

 appendages, hardly inflated, faintly tinged with brown, tapering very 

 slightly to the tip, which is suil'used with dark brown, broad, hardly dif- 

 ferentiated and slightly asymmetrical. Receptacle very long and slen- 

 der, the cells of the main axis thirty to forty in number, dark reddish 

 brown or nearly opaque, subhyaline below the somewhat oblique septa, 

 except the lower members of the series, which are as a rule wholly 

 opaque ; the cells increasing slightly in size from the base upward. 

 Appendages straight, narrower distally, rather short and appressed, not 

 very numerous ; those about the base of the perithecium, about twelve 

 in number, somewhat larger and longer than the rest, surrounding and 

 concealing it more or less completely ; some of the lower appendages 

 also longer and curved conspicuously outward, as are the antheridia. 

 Perithecia about 110 X 30 /a. Longer appendages about 140-1 GO /x. 

 Greatest width of receptacle about 20//. Total length to tip of peri- 

 thecium 800-1000 u.

Rhachomyces Cryptobianus nov. sp. 



Perithecium hyaline or pale straw colored, very long and slender, 

 nearly isodiametric throughout, almost straight, the tip apparently blunt 

 and not well differentiated. The main axis of the receptacle consists 

 of about sixteen cells ; the basal cell and those immediately above it 

 slender black and opaque ; the rest becoming larger upward, hyaline 

 suffused or mottled with reddish brown. Appendages numerous slightly 

 divergent, becoming longer from the base upward, nearly opaque except 

 along the inner margin and at the tip which is generally bent abruptly
