peatedly branched, with short, slightly inflated segments, and 
conidia terminal. The type’of branching is fusarioid. 
This type of fructification resembles Pseudomicrocera in form 
and in its parenchymatous base, though its general appearance 
is different owing to the more obvious development of the disc. 
It differs from Pseudomicrocera, however, in the type of conidio- 
phore, and in the continuous wall of parallel hyphae which 
forms the outer layer of the whole sporodochium. It is a 
Fusarium, with the general shape of a Peziza. I propose to 
call this Disco-fusarium. 
Disco-fusarium gen. nov. Tuberculariaceae. Sporodochium 
discoid, sessile or shortly stalked, the external layers composed 
of parallel hyphae, continuous from the base, extending above 
the disc and forming an incurved margin; disc composed of 
branched conidiophores; conidia hyaline, fusarioid, multiseptate.

PODONECTRIA. 
A Nectria with long, septate spores, parasitic on scale insects 
on orange trees in Florida, was described by Ellis and Everhart 
in 1886 as Nectria coccicola. They stated that it belonged to the 
subgenus Ophionectria, and subsequent references to it have, 
until recently, employed the latter name. 
A similar fungus was found by Zimmermann in Java on 
Parlatoria 2zyphi on Citrus, and was regarded by him as the 
same species. He also described the conidial form, which was | 
not recorded by Ellis and Everhart. 
The perithecia (Plate IV, fig. 9) are pale to dark brown, thick- 
walled, with thick-walled asci, which are furnished with para- 
physes, and contain long, clavate, septate spores, 100-120 uw 
long. The conidial stage (Plate IV, fig. 9) is strikingly different 
from that of other species of Nectria; it consists of a short 
parenchymatous column, which bears at the apex a white, 
conical head of conidia. The conidia (Plate V, figs. I-3) are 
long and septate; they are borne, usually in threes, at the apex 
of the conidiophores, and they remain united together at the 
base when detached from the conidiophores. The number in a 
detached cluster varies, however, from three to five. 
In 1913, Miyabe and Sawada recorded Ophionectria coccicola 
from Formosa, where it occurred on Parlatoria zizyphi (Lucas)
