Hab . — Pn fimo ovino et in charta, Kew, Nov. 1901. 
The above species appeared on some Sheep-dung sent from the 
Gold Coast, Africa, by Mr. W. H. Johnston, after the dung had 
been kept for a month or so at Kew. The Chaetomium soon appeared 
also on the paper surrounding the dung. C. arachnoides is very 
different in appearance from the commoner species of the genus, such 
as C. murorum, Corda, C. elatum> Kze, &c., on account of the 
extremely long flexuous hairs, which exceed ten times or more the 
diameter of the perithecium, and which diverge widely on all sides. 
These hairs are often fasciculate at the base, and more or less 
uncinate at the apex, below which they are sometimes angularly 
bent. In the early condition the perithecium is almost naked, a few 
short hairs being present only round the apex. These hairs after- 
wards grow out into the long flexuose divergent appendages, while 
the lower portion of the perithecial wall disappears. When perfectly 
ripe the Fungus is found to consist of an interwoven mass of hairs, 
containing fragments of the perithecial wall amongst a dense mass of 
loose clear yellowish-brown spores. At maturity each perithecium, 
owing to the disappearance of its lower part, becomes perfectly loose * 
and free on the substratum.
