and by Ellis 0 who followed Saccardo using the combination 
Hypocrella liypoxylon (Pk.), but also included as synonyms 
Hypocrea atramentosa B. & C., and Dothidea vorax, atramenta- 
ria and pilulaeformis of B. & C., and Cooke * 7 says “according to 
specimens in Ellis & Everhart’s North American Fungi, this” — 
(Epichloe liypoxylon Pk.) —“is identical with Hypocrella atra¬ 
mentosa Berk. & Curt., in Saccardo Syllog, No. 5066.” This 
confusion in the identity of the plant led me into a serious mis¬ 
take several years ago because I accepted specimens of a fungus 
marked “ Hypocrea liypoxylon Pk.,” distributed in several her¬ 
baria as identical with Peck’s species, not having had access at 
that time to the type specimen. The specimens marked “ Hypo¬ 
crea liypoxylon” to which I refer, it was easy to see were identical 
with Hypocrea atramentosa B. & C., which is quite common on 
blades of Andropogon and other grasses in the Southern States 
as I had occasion during my residence in Alabama to learn. 
Unfortunately therefore the Epichloe hypoxylon Pk., and Hypo¬ 
crea atramentosa B. & C., were considered by me at that time to 
be identical, when in reality I had seen only specimens of the lat¬ 
ter, some of which had been determined as Epichloe hyphoxylon 
by a misunderstanding. At that time Hypocrea atramentosa 
B. & C., was made by me the type of a new genus Dothichloe . 8 
While it was intended, therefore, that Hypocrea atramentosa 
B. & C., should be the type of the new genus Dothichloe, and it 
was the plant which I had especially in mind for the type species, 
unwittingly the name of an entirely different fungus ( Epichloe 
hypoxylon Pk.) was included. Since this species name was the 
earlier one it was employed with the result that Dothichloe 
hypoxylon (Pk.) would actually refer in name to a plant which 
did not at all agree with the concept of the species actually used 
as the type of the genus. A few years ago I had an opportunity 
of examining the type of Epichloe hypoxylon in the State Her¬ 
barium at Albany and found that it was an entirely different 
plant from Hypocrea atramentosa B. & C. 
It is in fact a Balansia as I discovered in my study of this 
species in 1901. During that year Professor Kellerman collected 
a considerable quantity of fine material at Vinton, Gallia Co., 
Ohio, on Danthonia spicata some of which he communicated to 
me. The pseudosclerotium is curved, more or less irregularly 
formed in the spike, 4-8 mm. long and 2-3 mm. in diameter. It 
is gray in color, whitish within, often with irregular rifts in 
the interior between adjacent elements of the spike. The layers 
are composed of the interwoven threads of the fungus with disin¬ 
tegrated remnants of the cells of the palae, leaves, axils, etc., of
