 Isaria Sphingum Schw. Schr. Nat. Ges. Leipzig 1 : 126. 1822. 

 Torrubia Sphingum Tul. Fung. Carp. 3 : 12. 1865. 



Stromata numerous, as many as thirty often springing from a 

 single sclerotium, very slender and thread-like, about 5 cm. high 

 and 1 mm. in thickness, cinereous, smooth or slightly pruinose, 

 enlarged at the base, more or less bent above ; perithecia subsuper- 

 ficial, subconic, 125-150 X 200-225 mic, brownish; asci elongate, 

 cylindric ; spores filiform, as long as the ascus, about 2 mic. thick 

 (pi. 54, /• n).

Jour. Inst. Jamaica 1 : 180. 1893 

 Ophionectria Cockerellii Ellis & Everh. ; Ellis, Jour. Inst. Jamaica 

 1 : 141. 1892. 



Stromata effuse, spreading over and almost covering the sub- 

 stratum, or erect and 1-2 mm. high, yellow ; perithecia occurring 

 in cespitose rounded or irregular clusters, or scattered, subsuper- 

 ficial or nestling in the substratum ; individual perithecia elongate, 

 flask-shaped or cylindric, about 1 mm. high and 0.5 mm. in 

 diameter, reddish-brown or slightly translucent, smooth, at ma- 

 turity collapsing laterally, becoming spathulate in form ; asci very 

 slender, about 1 mic. thick, breaking up into short segments 

 (pi. 54, f.6-8).

Type locality: Jamaica. 



Distribution : Jamaica. 



Specimens examined: Bath, Jamaica, Mrs. Swainson (Type). 



This species, which is said by Professor Cockerell to occur on 

 a sphingid moth, is similar in perithecial and spore characters to 

 C. Sphingum. The stromata in this species, however, are effuse 

 or very short while in C. Sphingum they are very long and 

 slender. This may be only a variation of the former species.
