Nov. 1905 ] The Genera Balansia and Dothichloe, Etc. 255 
ferent structure. Asci cylindrical with a tapering pedicel and a 
hyaline cap ‘cedi/ 120-200 x 6-8 jx. Spores 8, filiform, nearly 
the length of the ascus, about 1 fx in diameter, at maturity sepa¬ 
rating into segments 3-4 /x in length or longer. Conidial stage 
of the Ephelis type, stromata at first convex, emerging, then pezi- 
zoid and slightly margined. Conidia acicular, hyaline or pale 
yellowish, nearly straight or curved, ends obtuse, 15-25 x .5-.75 
fx. On Danthonia spicata, Nova Scotia, Maine, Conn., New York, 
Ohio; and other grasses, South Carolina, Texas ( PMexico). 
The name Balansia vorax might well be retained for that por¬ 
tion of Berkeley’s species from Khasia occurring on the inflor¬ 
escence of a Carex, especially since this form is the first one 
appearing in the original description. But since Berkeley gave 
an incomplete description of this form and confused it with a 
species of another generic type it may be well here to add a 
description of the species: 
Balansia vorax (B. & C.) Emend Atkinson. PI. 87, Figs. 
19 and 20. Pseudosclerotium in type specimen over 30 mm. long 
by 5-8 mm. in diameter, made up of elements of the fungus and 
the inflorescence of the host, of a coarse texture and rather coarse 
surface, more or less irregular in outline, not so smooth and com¬ 
pact as in B. hypoxylon, black. Stromata scattered over the sur¬ 
face, pulvinate, hemispherical or depressed, black, .5-1.5 \x in 
diameter, surface minutely punctate from the slightly projecting 
ostiola. Perithecia ovate, elliptical, 200-300 x 120-150 fx. Asci 
150-180 x 6-7 fx. Spores 8, nearly as. long as the ascus, separating 
at maturity into short segments. On inflorescence of some Carex, 
Khasia, India. 
? Balansia discoidea P. Hennings. There are specimens 
of a fungus parasitic on the stem of an Andropogon from Kansas* 
in the Ellis Herbarium at the New York Botanical Garden marked 
(< Dothidea vorax B. & C.” in Ellis’ handwriting, and with the fol¬ 
lowing note in Kellerman’s writing “On Andropogon, Kansas. 
Spores filiform, multinucleate, yellowish, 8 in an ascus. Keller- 
man & Swingle.” These seem to be specifically different from 
both Balansia hypoxylon (Pk.) and Balansia vorax (B. & C.). 
The specimens which I have examined are rather old and asci 
and spores had disappeared from the stromata sectioned and 
shown in Plate 84, Fig. 11. The spores are, however, septate, 
120-150 fx by slightly less than 1 /x in diameter and at maturity 
separate into short segments. A photograph of a portion of a 
grass stem affected by this fungus is shown in Plate 87, Fig. 19. 
The general stroma or pseudosclerotium is thin, dark gray, unit¬ 
ing only with the outer elements of the host. The stromata are 
prominent, discoid, sessile and punctate with the mouths of the 
perithecia and vary from .5-1.2 mm. in diameter. So far as one 
can judge from its appearance it seems to agree with Balansia
