One of the sporodochia described above bears a few perithecia 
partly embedded in it, and crowded together at the edge. The 
other bears similar perithecia, somewhat crowded, situated all 
over the sporodochium, and embedded in it. The available 
specimens have been pressed; in them, the upper part of the 
perithecium does not project above the sporodochium, but it 
would appear probable that in a natural condition the peri- 
thecia projected for about one-third their height. The perithecia 
agree exactly with those of Nectria Tuberculariae: the asco- 
spores are narrower, 6-8 x 2-5-3, but they are immature. 
This specimen differs from the type in the absence of the 
byssoid stroma which is so noticeable in the former collection, 
and in the development of the perithecia in the old sporodochia. 
But it is too close to be separated on the present material. 
Nectria barbata n.sp. 
An undescribed species of Nectria was found on Lepidosaphes 
sp. on Citrus aurantium, Glenugie, Ceylon, March 19109. 
The perithecia are scattered over the scale, without any 
stroma, sometimes with a slight basal weft of hyphae. They 
are conoid or subglobose, about 0-2 mm. diameter, and 0-3 mm. 
high, collapsing, minutely rugose, yellow-brown or dark amber, 
subtranslucent (Plate III, fig. 14). The ostiolum is broadly 
papulate or obtusely conical, and is surrounded, at a short 
distance below, by a varying number of erect, white, rigid hairs, 
arranged more or less in a ring. These hairs (Plate V, fig. 4) 
are up to 50 high, 4p diameter below, equal, or slightly in- 
flated at the obtuse tip. The perithecial wall consists of an 
outer, brown, collapsed or amorphous layer which splits into 
irregular patches, and an inner, hyaline, membranous wall com- 
posed of moderately large cells. The asci are cylindrico-clavate, 
eight-spored, 66 x 6-8, with spores uniseriate, or obliquely 
uniseriate, or sometimes transverse (Plate V, fig. 5). The 
spores (Plate V, fig. 6) are hyaline, oblong-oval, ends broadly 
rounded, one-septate, strongly constricted, 6-8 x 3-5 p. 
I name this species Nectria barbata. Its conidial stage has 
not been observed. 
LISEA. 
Lisea Parlatoriae Zimm. 
This species was described from specimens on Parlatoria 
zizypht Luc., on Citrus leaves, found at Buitenzorg, Java. 
The perithecia are crowded, superficial, globose with a papil- 
late ostiolum, 0-2—0-25 mm. high, and o-15-0-18 mm. diameter, 
appearing black. By transmitted light, the colour of the peri- 
thecial wall is dark violet to black, becoming red-violet on
