32 Mas see. — A Revision of 
Stem simple, elongated, slender, cylindrical, often flexuous 
or angularly crooked, brown, minutely velvety at the base, 
glabrous above, 5-8 cm. long, ii mm. thick ; head cylindrical, 
acute, i-ii cm. long, 3 mm. thick ; perithecia blackish, large, 
ovate, apex truncate and indented, quite superficial and free 
from each other at the base ; asci subcylindrical, elongated, 
apex capitate, pedicel short, 8-spored ; spores arranged in 
a parallel fascicle in the ascus, hyaline, cylindric-filiform, 
ends very slightly narrowed, straight or curved, multiseptate, 
130 x 2-5 ju,, component cells about 3*5 \ u, long. 
On larvae buried in the ground in damp, shaded woods.

(Host-Index, p. 181). 
Type specimen in Herb. Kew., examined. 
Ravenel’s label accompanying the specimen has ‘ Sphaeria 
acicularis n. sp.?,’ but the specific diagnosis was drawn up by 
Berkeley, who accepted Ravenel’s MS. name. 
The apex of the head is not sterile, but as in other species 
with superficial perithecia, these fall away readily when 
mature, and had done so from the apex of the head in the 
specimen described by Berkeley, but in several other speci- 
mens of the same species, the head is completely covered 
with perithecia. Structure of wall of perithecium truly 
parenchymatous ; external cells irregularly polygonal, pale 
brown, 8-12 fx diameter.

Caespitose; stem 1J-2 cm. long, about 2 mm. thick, equal, 
even, glabrous ; head elongated, narrowly elliptical, apex 
acute, slightly curved or falcate, about 2 cm. long, and 4 mm. 
thick at the widest part ; perithecia perfectly superficial, ovate, 
mouth somewhat narrowed and elongated, crowded ; asci 
cylindrical, apex slightly capitate, base narrowed into a short, 
slender pedicel, 8-spored ; spores arranged in a parallel fascicle 
in the ascus, slightly curved when free, hyaline, filiform,
