fructification evident there under a magnification of forty dia- 
meters. This conidium is strongly curved, up to two-thirds of 
a circle, fusoid, hyaline, one- to three-septate, with obtuse tips, 
12-16 x 4, measured from tip to tip, not round the curve. 
The perithecia (Plate III, fig. 3) are situated round the scale, 
scattered or clustered, with no evident stroma, but usually 
attached by a few inconspicuous radiating hyphae. As a rule, 
they occur round scales which do not bear the conidial synne- 
mata. But, as noted by Berkeley and Broome, perithecia also 
occur at the base of the synnemata, or along their stalks, or 
even among the conidiophores in the head. This however only 
occurs on the larger synnemata, and even on those it is not 
the rule. I have only one collection in which this occurs, and 
in that the perithecia on the synnemata are immature. Parkin 
illustrates this position of the perithecia in his figure 9. 
The perithecia are smooth, or pruinose with a few yellow 
granules, subsequently becoming smooth, very minutely rugose 
when highly magnified, 0-2—-0-25 mm. diameter, subglobose, with 
a broad papillate ostiolum, or subconoid, scarcely papillate 
(Plate III, fig. 4). They are usually orange-red, becoming blood- 
red or dark red, and subtranslucent, but immature examples 
may be orange-yellow. The latter may account for Berkeley 
and Broome’s “‘aurantiacis,” but it is more probable that they 
gave the colour of the wall by transmitted light. In old examples, 
the wall, when mounted, is red-brown, but younger examples 
show an orange-yellow wall, though viewed as opaque objects 
they are orange-red. This is a common phenomenon in red 
Nectrias in the tropics. The cells of the perithecium wall are 
thick-walled and up to 12 diameter, though the structure is 
usually obscure. The ostiolum is fimbriate. 
The asci are cylindrico-clavate, scarcely pedicellate, eight- 
spored, with diffluent paraphyses with granular contents. The 
spores may be uniseriate, or obliquely uniseriate, or obliquely 
uniseriate above and uniseriate below. The dimensions of the 
asci in different gatherings are 72-80 x 6-7; 70-80 x 7; 
70-88 x 6; 66-74 x 7-9; 70-90 x 7-8; 74-80 x 7p; 70- 
80 x 7-8 p. 
The ascospores are oval, or broadly oval, ends obtuse, hyaline, 
becoming yellowish, wall rather thick and minutely warted, 
one-septate, not constricted at the septum, except slightly in 
old extruded spores. Their dimensions in different collections 
are, Q-I2 X 5-Op; 10-12 X 4-5; II-I3 X 5p; 9-13 X 5-6; 
II-I3 xX 5-Op; 10-14 x 5-6; 10-14 x 4-6. 
I have the following recent collections of this species. On
