On a paper box under a bell glass. April. 



Sporidia when young, '0004--0005, mature, -0007 in. Perithecia 

 globose, with a pointed apex, composed of about three rows of 

 coarse cells, of a pallid ochre at first, attached by a few threads. 

 Ostiolum (if any) very inconspicuous ; asci mostly curved, obtuse 

 at either end, the narrow base soon losing all signs of attachment 

 and floating freely in the perithecium ; sporidia spherical, strongly 

 granulated, of a pale-brown tint, containing a small nucleus.

Chaetomium glabrum. B. (Cooke " Handbook," No. 1934.)

 m.m. diam. — B. §■ Br. Ann. N. II., No. 1397,* t, x.,fig. 13. 



On the same matrix Lycogala parietinum occurs, and we have 

 little doubt that it is a mere state of the Chcetomium. The asci 

 are mixed np with yellow threads, and it is probable that, as in 

 other Chcetomia they are often absorbed, leaving the sporidia free, 

 and thus appearing to be the spores of a Mt/xogaster.
