Chaetomium simile, Mass. § Salm., in Ann. Bot., 16, p. 71, pl. 4, 
figs. 8-9 (1902); Sacc., Syll., 17, p. 600 (1905). 
Perithecium subglobose, 50-75 broad, blackish-brown ; mouth 
small, papillate, pale; crown-hairs brown, smooth, loosely and 
interruptedly spirally twisted, some coils from left to right, others 
in the opposite direction, tips often uncinate, the whole forming a 
dense tuft of a dusky olive colour; hairs on the body of the 
perithecium short, straight, pointed, brownish. Asei cylindrical, 
80-90 x 10u. Spores obliquely 1-seriate, broadly elliptical or 
subglobose, compressed, one end minutely apiculate, the other end 
rounded, olive-brown, 8-10 x 7*5u. Conidia unknown.

Most nearly allied to C. crispatum, Fuckel, which differs in 
having larger spores, apiculate at both ends, and in the crown-hairs 
being more closely spirally coiled throughout their length, and 
mixed with other hairs only slightly flexuous.

tabs, 1-3, tab. 4, figs, 1-13 (1881). 
_ Pertthecium broadly elliptical, dark brown, 300-350 high, about 
250u broad ; mouth papillate, pale; crown-hairs very long, wavy, 
sometimes with a curl at the tip, stout, dark brown sometimes olive 
or yellowish, asperate, collectively forming a large, dense tuft ; 
hairs on the body of the perithecium stout, straight, pointed, dark 
coloured. Asei clavate, with a stem of variable length, averaging 
100 x lly. Spores irregularly 2-seriate, broadly elliptical, laterally 
compressed, minutely apiculate at both ends, 11-14 x 8-1Uy, olive- 
rown. Conidia are produced on the hyphae of germinating spores, 
similar to those described under C. pannosum.

A very yariable species, the extreme forms of which, seen 
independently, have been mistaken for distinct species, but which, 
when an extensive collection is available, are found to be connected 
with each other by intermediate forms. 
he colour of the hairs ranges from blackish-brown, through olive 
to yellow.

broad, blackish-brown; mouth small, paler; crown-hairs elongated,

spreading branches, the whole forming a dense; erect tuft ; hairs on
