MONOGRAPH OF CHAETOMIUM AND ASCOTRICHA 179 
Asci club-shaped, 8-spored, 30 Х 9.4 и, pars sporif. 16.5 д. Spores 
hyaline when young and filled with refractive greenish globules, 
when mature dark, rich olive-brown, ovate to lemon-shaped, 
slightly apiculate at one or both ends, 5.5 X 4.5 и (5.3-7 X 4.5- 
5-6), when seen edgewise, compressed, 4.2 ш broad. 
On culture in laboratory, Cambridge, Massachusetts, R. Thax- 
ter (Chivers No. 14). Reported by Spegazzini from Parque de la 
Plata, Argentine, and by other authors from France and Germany. 
Reported also as Ch. melioloides by Cooke and Peck, on old stems 
of Indian corn, North Greenbush, New York, and as Ch. setosum 
by Winter on branches of Berberis buxifolia in Patagonia. Type 
locality: India, Tenasserim, Maulmain; on rotten paper (Dr. 
Helfer). 
While this species seems to have been clearly described and 
figured by Corda, it has since been re-described by Cooke and 
Peck in 1875 as Ch. melioloides, and by Winter in 1887 as Ch. 
setosum. 
The writer must here acknowledge his indebtedness to Dr. 
Charles Peck for his generosity in furnishing specimens of Ch. 
melioloides as well as several other of his species. In answer to 
inquiry regarding the possible identity of Ch. melioloides with 
Corda's СВ. indicum, Dr. Peck kindly sketched with a camera 
typical hairs and spores, and wrote as follows: “The two species 
certainly run close together and if I were inclined to overlook small 
differences I could easily make myself believe that they are forms 
of опе species. 1 notice, however, that the spores of СЁ. indicum 
are more elliptic as required by the description of the species, and 
that they run a little longer than in our plant. But I never would 
think of describing them as acute at each end. Can this be а 
mistake in the description or is it due to culture modifications? 
After a very careful examination of the two plants, the present 
writer is convinced that the two are identical and that Dr. Feck: 
name should appear as а synonym to Ch. indicum. The hairs as 
sketched by Dr. Peck and the spores as studied in mounts from 
the type specimen are typical of Corda’s species. 
Through the kindness of M. Hariot the writer has been able 
to study Ch. setosum Winter, and it has been found that the plant 
thus named is identical in every way with Ch. indicum Cda. It 
Produces the same dichotomously branched hairs with widely
