Studies in Entomogenous lungi. 1. Petch. 139 
with rounded ends, up to 6 x 2:5, or oval, 3-5 x 2-3, or 
globose 2:5 » diameter, hyaline, continuous. 
This conidial form appears to be identical with 7ubercularia 
coccicola Stevenson, which was found on Lepidosaphes beck and 
Hemichionaspis minor, on Citrus, in Porto Rico, in company 
with Ophionectria coccicola, and species identified as Sphaero- 
stilbe coccophila and Microcera Fujtkurot. 
Tubercularia coccicola was described as having scattered, or 
clustered sporodochia, superficial, pulvinate, compact, from 
0-5-4 mm., averaging I-2 mm., sometimes uniting irregularly, 
erenadine pink to safrano pink (Ridgway), fading to dull white 
with age; margin regular, not setose; conidiophores hyaline, 
septate, 15-36 long, 1-5 diameter; conidia forming dense 
masses on the sporodochia, pink in mass, hyaline by transmitted 
light, ovoid to cylindric, not guttulate, 2-4 x 1-5-2 p. 
Mr Stevenson has kindly forwarded me a specimen of 7 uber- 
cularia coccicola, on Lepidosaphes beckit on Citrus decumana, 
Espinosa, Porto Rico, March 1917 (No. 6366, Insular Experi- 
ment Station, Porto Rico). The individual sporodochia are 
usually small, but they may be confluent in large masses; they 
are flattened-pulvinate, circular or oval, usually somewhat 
pruinose in the dry specimens, but sometimes waxy. The coni- 
diophore is the same as in the Ceylon form, and there is the 
same mixture of narrow-oval and globose spores. In general, 
the sporodochia lack the byssoid stroma which is so prominent 
in the Ceylon form. A slight development of the stroma is 
however present in some cases, and it would appear probable 
that the difference between the Ceylon and Porto Rican forms 
in this respect may be a climatic effect. The two forms are too 
close to be separated as conidial stages of different fungi, though, 
when the difficulty of differentiating between other conidial 
forms of fungi found on scale insects is borne in mind, it must 
be admitted that the discovery of the Nectria of the Porto 
Rican fungus might demonstrate that they are not identical. 
A specimen from South India differs in some respects from 
the type. It was collected on the Western slope of the Nilgiris, 
October 1910, on the stems of a small bamboo (indet.), asso- 
ciated with an Asterolecanium. Only two sporodochia are 
present. The sporodochia are superficial, circular, up to 
25mm. diameter, flat, thin, with a definite edge; there is no 
spreading mycelium. The base of the sporodochium is somewhat 
lax, composed of loosely interwoven, slender, hyaline hyphae 
up to 2y diameter; the upper portion consists of a definite 
continuous layer of erect conidiophores. The conidiophores are 
short, about 12m high, simple, with conidia, narrow-oval, 
hyaline, 2-4 x 1*5-2. The colour of the stroma is now white.
