Readily recognised by the éylindvical ascus, l-seriate spores, and 
the crown-hairs being of two forms. Most closely allied to 
C. spirale, — which differs in the broadly clavate ascus, and 
2-seriate spore

Perithecium varying from broadly elliptical to subglobose, 
pier 150-2504 high, by 150-200u broad, blackish-brown, 
outh minute, paler ; crown-hairs cylindrical, dark coloured, thin, 
: slightly wavy throughout their length, and with a small curl at the 
tip, often asperate, the whole forming a large, rather loose tuft ; 
hairs on the body of the perithecium short, pointed, dark coloured, 
often vege Asci broadly clavate, shortly stalked, 80-100 
x 1l-14u. Spores 2-seriate, elliptical, minutely apiculate at each 
end, dark brown, laterally compressed, 14-18 x 8-9u. Conidia 
unknown

a Petri dish, Jodrell Laboratory, Kew. 
Distinguished <i the long, flexuous crown-hairs, with a small, 
close curl at the 
Chaetomium seiilade Mass. & Salm., in Ann. Bot., 16, p. 71, 
pl. 4, figs. 97-103 (1902); Sace., Syll., 17, p. 600 (1905). 
Perithecium small, subglobose, blackish, 2004 high by about 
1804 broad ; mouth small, papillate, pale ; crown-hairs very long, 
slender, wavy, often circinate at the tip, 4-54 thick, smooth, dark 
coloured, collectively forming a large, widely spreading tuft ; hairs 
on the body of the perithecium ” short, straight, pointed, dark 
coloured. Ascus clavate, averaging 36 x 12u. Spores irregularly 
2-seriate, broadly elliptical or subglobose, laterally compressed, 
yellowish brown, 7-9 x 5-6u. Conidia unknown 
Haxs.—On sheep’s dung, and on damp blotting-paper. 
Readily distinguished by the very long, flexuous crown hairs, 
which are often fasciculate at the base, and more or less circinate at 
the tip.
