cells, up to 10 diameter can be recognised. The wall bears 
projecting cells, or one-septate processes, sometimes growing 
from the cells of the wall, and sometimes appearing to be 
merely fastened to it by a yellow substance. The ostiolum is 
fimbriate. When detached, the perithecium usually has a 
minute, and somewhat compact, mass of mycelium at the base. 
The asci are cylindrico-clavate, i.e. cylindric, slightly attenu- 
ated below, and usually shortly pedicellate. They are accom- 
panied by long, linear paraphyses, which disappear before the 
asci are mature; the paraphyses have granular contents. The 
asci are eight-spored, and the spores slightly obliquely uni- 
seriate. Measurements of the asci from different collections gave 
IO5-II5 X 9-10 px; 100-106 X IO p; IOO-IIO X 10 p; I16—136 x 
10 p; 84-102 x Bp. 
The ascospores are oval, or broadly oval, one-septate, thick- 
walled, ends obtuse, hyaline, becoming yellowish, not constricted 
at the septum, wall minutely warted, 13-22 x 7-gp. Measure- 
ments from different gatherings are 17-20 x 8-g p, one 14 x 6, 
another 16 x 5 p (old spores; asci not present); 14-20 x 7-9 p, 
a few 17-18 x 6p; 13-16 x 8-gp, with some, in the ascus, 
globose, continuous, thick-walled, 9-10 diameter; 13-18 x 
7-9, one 16 X 5p; 16-22 x 8-gy. The specimen on Chion- 
aspis biclavis on Tabernaemontana has spores 14-17 X 6-7 p, 
in asci 84-102 x 8 p, but in all other respects it does not differ 
from the other gatherings. 
Parkin recorded a Nectria on Asterolecantum muliaris on 
Bamboo which he considered different from Nectria coccidoph- 
thora. The available perithecia on this specimen are immature, 
but they resemble those of Nectria coccidophthora, in being 
covered with yellow granules. From one old weathered peri- 
thecium, however, spores, some of them germinating, were ob- 
tained, which measured 21-27 x 9-10 p. They are oval, some- 
what attenuated towards one end, slightly constricted, pale 
yellow,, thick-walled, with the wall minutely warted. Parkin 
describes them as elliptical and somewhat pointed, 22-27 x 9- 
10, and the ascus as II5 x 13:5. He also records that the 
conidia, which are not now present, measured I00—-IIO x 
5°5-7°5. The constriction of the ascospores may be dis- 
regarded, as extruded Nectria spores frequently swell, so that 
they become constricted at the septum, but the dimensions of 
the spores are greater than anything observed in Nectria cocci- 
dophthora. The specimen, however, is not now in good condi- 
tion, and, provisionally, I would refer it to Nectria coccidoph- 
thora on the general characters of the perithecium.
