162 MONOGRAPH OF CHAETOMIUM AND ASCOTRICHA 
species, rather than as a synonym of Ch. bostrychodes Zopf; Ch. 
lanosum Peck and Ch. olivaceum С. & E. appear as species, rather 
than as synonyms to Ch. globosum Kze. Тһе name Ch. Ellisianum 
Sacc. is retained for the plant which the present writer has re- 
named Ascotricha pusillua (E. & E.); Ch. contortum Peck is treated 
as a synonym to Ch. crispatum Fuckel, rather than as a distinct 
species; Ch. melioloides C. & P. is recorded as a species, rather than 
as a synonym of Ch. indicum Cda.; Ch. sphaerospermum С. & E. 
is treated as a species of the genus Chaetomium rather than as 
Ascotricha chartarum Berk.; Winter's name, Ch. setosum, is re- 
tained and Ch. indicum of Zopf, but not of Corda, appears as a 
synonym thereto. 
The monograph of the genus Chaetomium by Bainier contains 
a brief historical sketch and review of the work on development; 
a characterization of the genus; a description (with figures) 
of twenty-two species and three varieties, twelve species and two 
varieties of which are described under new names as follows: 
Ch. megalocarpum, Ch. contortum (not of Peck), Ch. spirilliferum, 
Ch. undulatum, Ch. setosum (not of Winter or of Ellis & Ever- 
hart), Ch. comosum, Ch. glabrum (not of Berkeley & Broome), 
Ch. tortile, Ch. formosum, Ch. formosum, var. ovatum, Ch. formosum, 
var. neglectum, Ch. caprinum, Ch. torulosum and Ch. rigidulum. 
The most striking characteristic of Bainier's monograph is the 
multiplication of species and the fact that several species and 
varieties have been made from Ch. globosum Kze. and Ch. bostry- 
chodes Zopf, both of which are variable forms. It should here 
be noted that three of the names used by Bainier, viz., Ch. con- 
tortum, Ch. setosum, Ch. glabrum, must, if the priority rule is to 
be followed, be changed, since Dr. Peck had previously used the 
name contortum; Winter, and later Ellis and Everhart, had made 
use of the name setosum, and Berkeley and Broome had used the 
name glabrum.
