DOTHICHLOE. 
In Berkeley’s description of Dothidea vorax quoted above 
he made no note of the vegetative stroma or sclerotium of the 
Balansia form on the Cyperaceous plant from Khasia, as is evident 
from the words ‘‘black, subglobose, varying in size from a mere 
speck to that of a millet seed,” . . . This applied to the fruit¬ 
ing stromata of the Balansia which are very easily seen in this 
part of the type on the pseudosclerotium which is the “deformed 
spike of some Carex.” 
The description further reads “or altogether effused, minutely 
granulated.” This form is on Uniola and Panicum from South 
Carolina and is the form referred to by Berkeley as Dothidea 
atrament aria . 21 Berkeley never published a description of this 
species and it is evident from a study of the specimens in the 
Royal Herbarium at Kew with notes in Berkeley’s handwriting 
that he confused the species names atramentosa and atramentaria 
which were applied by him to the same plant. For example, a part 
of the type of his Hypocrea atramentosa 28 is the No. 4018, on An- 
dropogon, from Alabama. The type specimen now at Kew has the 
following note in Berkeley’s handwriting: “No 4018. Hypocrea 
atramentaria B. & C., on Andropogon, Alabama, Beaumont,” but 
when he published the species it was written atramentosa. On 
the same sheet in the Royal Herbarium at Kew is the specimen 
from Cuba also referred to Hyprocrea atramentosa in Berkeley’s 
handwriting as follows: “419. Hypocrea atramentosa B. & C., 
Cuba, Wright.” 
While Berkeley never published any description of u Dothidea 
atramentaria ” Saccardo practically published a description of the 
plant as “var. atramentaria” of his Ophidothis vorax 29 , which he 
drew up from the specimen in Rav. F. Am., No. 100. 
The stroma of Hypocrea atramentosa B. & C. varies consid¬ 
erably, sometimes well and quite evenly developed, but always as 
a thin layer on the surface of the host and its thickness not exceed¬ 
ing the length of the perithecia or very slightly. The bases of 
perithecia, therefore, extend nearly to the surface of the host and 
there is only a very thin portion of the stroifia between the bases 
of the perithecia and the host (see Plate 85, Fig. 1, a section 
of the type material of Hypocrea atramentosa B. & C.) while in 
Balansia there is an abundant development of the stroma between 
the bases of the perithecia and the pseudosclerotium. In other

here to express my obligations to Dr. Dyer, Director of the Royal Gar¬ 
dens at Kew, and to Mr. Massee of the Hebarium for the privileges ex¬ 
tended to me in the examination of Berkeley’s types of the species 
mentioned in this article.
