NEW OR CRITICAL MICROFUNGI 259 
Found on germinating grass seeds, Norwood, April, 1903. 
The genus Brachycladium was merged by Fries in Dendryphium 
Wallr., which is distinguished by the beanahitig conidiophores and 
by the ‘heads of conidia which are borne in chains. Hence in the 
latter genus a number of forms have been included with non- 
catenulate conidia, in spite of this being a distinctly generic 
character. To avoid confusion, it seems advisable to resuscitate 
Brachycladium to include all species with sin. catenulate conidia. 
In addition to the species recorded above, there would be included 
in Corda’s genus: B. ata a Corda, B. toruloides (Fries), B 
oospage (Cooke), B. curtum (B. & Br.), B. nodulosum (Sace.), B. 
ot m (B. & Br.), B. curtipes (Ell. & Barth.), B. crustaceum (Ell. & 
Ey. , B. pachysporum (Ell. & Ey.), and B. macrosporium (Karst.). 
Cidocephalum clavatum, sp.nov. Sterile hyphe creeping; 
fertile hyphx erect, stout, septate, occasionally branching to form 
a second head near the tip; ue me clavate-spherical, varying in 
size, about 25-80 » x 20-25 p, n late; spores yellowish, cylin- 
rical, apiculate at the basal oak” saree with blunt wa : ‘a 
5-6 m, rising from points on the head. (PI. 454, figs. 11, 12.)

as to its identification with T. inequale, but the ss at _
