conidiophores 3-4 fi in diameter, bearing obovate to elliptical or 
fusoid, hyaline conidia 3-4 x 1.5-2 fx. At first this was supposed 
to be the conidial stage, but this does not seem probable in view 
of the fact that the conidial stage of Balansia trinitensis C. & M. 
is an Ephelis, 9 and an Ephelis has also been found several times 
on the sclerotium on Danthonia spicata even accompanying the 
Balansia stage in the case of the Ohio specimens. The conidial 
fungus on the few Texas specimens may have been a parasite 
os saprophyte, or indeed a second conidial stage, corresponding 
to the microconidia of some Sphaeriales, but development studies 
will be necessary to determine this point. 
In examining the specimens carefully I discovered on some 
of the Ohio material the conidial stage which is of the Ephelis 
type, and it proved to be the Ephelis borealis 10 E. & E. The 
conidial stage Ephelis borealis as an “ imperfect fungus” is to 
be found among the Excipulaceae. The conidial fructification 
is a disk-shaped or cup-shaped structure resembling some forms 
of the Perzizales, but long slender conidia are found on the disk 
(Plate 86, figs. 15, 16). The discovery of a conidial fructification 
of the Ephelis type is additional evidence that this species is a 
Balansia, for Cooke * 11 and Massee have shown that Ephelis trini¬ 
tensis C. & M. is the conidial stage of Balansia trinitensis C. & M. 
In 1854 Berkeley described Dothidea vorax 12 as follows: 
“485. Dothidea vorax Berk, et Curt. Spicis deformibus 
caulibusque innascens, subglobosa vel omnino effusa, nigra, gran- 
ulata; cellulis minutis; ascis cylindriciis obtusis fragilissimis; spo- 
ridiis filiformibus. 
“Hab. on the deformed spikes of some Carex, Khasia 
(Churra), Aug. (Dr. Hooker.) On Uniola and Panicum, Rev. 
M. A. Curtis, South Carolina. 
“Black, subglobose, varying in size from a mere speck to 
that of a millet seed, or altogether effused, minutely granulated. 
Cells minute. Asci cylindrical, obtuse, curved, very fragile, spores 
filiform, extremely slender. 
“Nothing can be at first sight more different than the effused 
specimens on the stem of Uniola; but others on Uniola are much 
larger than the Khasia specimen, insomuch that the species was 
first named D. pitulaeformis A 13
