 the primary one, or antheridial branches; the secondary axes producing 

 autheridial or Bterile branches on both Bides, and like the primary ones 

 bearing a single terminal perithelium. The antheridia simple, born< 

 in Compsomyces, usually Beveral from the distal t-inl - of successive cells. 



Clcmatomyces Pinophili dot. »p. 



Nearly hyaline or yellowish, the basal and subbasal cells small, the 

 cells dt' the main axis in six to twelve pairs more or less alternate on 

 either side, each cell of the outer series giving rise to a three or four 

 celled usually simple generally appressed sterile appendage, the terminal 

 cell of which is often Bmoky brown, its basal cell almost wholly united to 

 the cell of the axis next above ; the secondary axes one to three ill 

 number, usually with a single basal cell, the external branches more often 

 simple and sterile, the iiimr fertile ; the antheridial appendages oi both 

 primary and secondary axes more often Bimple, Bometimea sparingly 

 branched, those near the perithecia bearing the greatest number of an- 

 theridia whicb may arise singly or opposite in pairs, or in whorls of three 

 or four from the distal (one to four) cells of the appendage. Perithecium 

 solitary, sessile at the tips of the primary and secondary axes, often 

 Btraight and symmetrical tapering to the truncate unmodified apex, pale 

 becoming amber brown. Spores about 38 X 3/t. Perithecia LOO— 150 

 X 25-40 ft. Sterile appendages, longer, 100X7 u. Greatest length 

 to tip of perithecium (main axis) 300-400 X 35 p.

Sphaleromyces obtusus no v. sp. 

 Perithecia relatively large, clear dark brown becoming almost opa<|iic : 

 tbe inner margin nearly Btraight, the outer strongly convex; tapering 

 very slightly basally and distally; the tip paler brown, abruptly distin- 

 guished, and when viewed sidewise flaring;, with Btraight divergent lateral 

 margins, tbe distal margin as broad as the portion of the perithecium 



below the tip and slightly concave, th iter lips more prominent and 



much broader than the inner: when viewed at right angles to this p 

 tion the tip appears in general bluntly rounded not expanded, the more 

 or less papillate tips of the lip-cells situated in asymmetrical pairs, which 

 are visible above ami below a broad bluntly rounded median portion 

 between them: the basal cells colored like the perithecium, distinct,
