312 SHEAR: NEW SPECIES OF FUNGI 
from the outer, except about the ostiole, and collapsing ; the epi- 
dermal cells of the host overlying the pycnidia usually blackened ; 
sporophores branched; spores hyaline, long fusiform, slightly 
curved, with 1-3 septa or pseudosepta, 20-26 x 2-3 y. 
Type, zo. 7479 C.L.S., on old leaves of Vaccinium macrocarpum 
lying on the ground under a pile of old vines which had been cut 
from an adjacent bog, near Whitesville, New Jersey, September 
2, 1904. 
Ceuthospora (?) lunata sp. nov. 
Pycnidia scattered, amphigenous, disciform, subpulvinate, 
buried, slightly erumpent, remaining covered, 200 to 375 p great- 
est diam., subcoriaceous, thick-walled, interior usually divided 
into irregular, incomplete chambers, opening through a rather 
prominent, slightly projecting ostiole; sporophores somewhat 
branched, ultimate divisions stout, shorter than the spores ; spores 
subhyaline or slightly greenish-yellow in mass, inequilateral or 
somewhat lunate, 7-9 x 3-3.5 #. 
Type, zo. 1488 C.L.S., on fallen leaves from vines of Vac- 
cinium macrocarpum which had been cut and piled on the margin 
of a cranberry bog near Whitesville, New Jersey, September 2, 
1904; also vo. 1489 C.L.S., on leaves of dead vines, Wareham, 
Massachusetts, September, 1902. 
The spores of this plant can scarcely be distinguished from 
those of Phoma cytisporea (Fr.) Starb. (Cytispora endophylla (Fr.) 
Sacc.). A scanty specimen in Fries’ herbarium which we have 
examined, differs from the type of our species in having thin-walled 
pycnidia, with a single, simple chamber. The Massachusetts 
specimens have somewhat smaller pycnidia than the type and fewer 
chambers. This plant is referred to Ceuthospora with doubt. It 
appears to belong to this genus as defined by Saccardo,* who 
credits the name to Greville.+ Fries,t however, was the original 
author of the genus and until it is revised its exact application 
cannot be determined.
