genus name be retained for the other species confused both by 
Berkeley and Saccardo with the Dothidea vorax, namely Dothi- 
dea atramentaria which Saccardo lists as a variety of O. vorax 
(B. & C.) Sacc., and D. pilulaeformis also listed by Saccardo as 
a variety. Two other species were enumerated as belonging to 
this genus ( 1 . c. 653). Of these Ophiodothis hay deni (B. & 
C.) Sacc. 24 cannot stand as the type of the genus Ophiodothis 
since it is a conidial stage of an imperfect fungus as I have found 
by examination of the specimens from the Kew Herbarium. The 
specimen in E. & E. Fungi Columbiani No. 1332 agrees with this. 
Berkeley’s description reads as follows: 
“881. Dothidea Haydeni B. & C. Irregularis papillata, sporidiis lin- 
earibus utrinque attenuatis. On stems of Aster and Erigeron, Nebraska, 
Hayden. No. 6404. Forming elongated, irregular, papillose patches, spo- 
ridia linear, attenuated at each end.” 
Berkeley did not give measurements of the spores. These 
are 15-25 x 3.5-4.5 /*, narrowly fusoid, or “linear and attenuated 
at each end.” The stroma is thin and the pustules are irregular. 
The third species (or the second one in order of position on 
the page) first placed by Saccardo in Ophiodothis (Syll. Fung., 
2, 653, 1883) is Ophiodothis edax (B. & Br.) — Dothidea edax 
B. & Br., and described by them as follows: 25 
“1167. D. edax B. & B. Minuta, punctiformis, nitida. e macula 
lutea oriunda; ascis lanceolatis; sporidiis filiformibus curvulis multinu- 
cleatis (No. 502). In leaves of Tephrosia suberosa. Sporida. .0002 
long. On the same spots are minute bright scarlet tendrils consisting of 
extremely minute spores, which are probably a second form of “fructifica¬ 
tion.” 
This species I have not seen and, therefore, cannot express 
an opinion as to its generic position or whether it sufficiently meets 
the characters ascribed by Saccardo to his genus Ophiodothis. 
Later species, however, described after the appearance of Sac- 
cardo’s publication of the genus come well within the genus and 
these might be regarded the types of the genus Ophiodothis. Of 
these I have had an opportunity of examining one, the Ophiodo¬ 
this tarda Harkness 26 . It occurs on dead leaves of Rhus diversi- 
folia. There is a thin 5 black, irregular, stroma, 3-4 mm. in diame¬ 
ter, punctate from the mouths of the perithecia. The asci are 
53-75 x 9-11 jx, pedicellate. There are 8 filiform spores, slightly 
curved, continuous, guttulate and 30-45 x 2 fx.
