The perithecia are totally immersed, pyriform, 0*25 mm. 
diameter, and 0*3 mm. deep. The perithecial wall is stout, 
and orange -yellow. The asci are cylindrico-clavate, 140-180 
X 11-12 with a very stout pedicel and a well-developed 
foot. Numerous paraphyses are present, and spermatia 
identical with the pycnospores. The ascospores are fusoid, 
or narrow-oval attenuated towards one end, thick-walled, 
wall rough, greenish-hyaline, 16-22 x 6-7 jjl. They are not 
septate, as far as I can discover from the co-type and from 
fresh specimens ; some spores show a pale transverse line 
near the centre, but, on staining with cotton blue, a broad 
blue band appears across the spore, showing a concentration 
of the cell contents there. 
It is evident that the fungus is a Hyponectria, and it may 
stand as Hyponectria Memecyli. Should the spores prove 
to be uniseptate ultimately, it would be Charonectria. 
179. — Diatrype irpex B. & Br. 
This was described by Berkeley and Broome in Fungi of 
Ceylon, 1083. They stated that it was “ late effusa,” and in 
Saccardo, II., p. 145, it is listed as Melogmmma. Berlese, 
leones Fungorum, Tab. XXVII., fig. 3, figures it under the 
name Rhyncosphæria irpex (B. & Br.) Berl. 
The perithecia are up to 0*75 mm. diameter, superficial, 
densely crowded, but not confluent, in large patches ; globose 
below, passing rather gradually into a long cylindrical ostiolum 
up to 5 mm. long, and 0*2 mm. diameter, black or black- 
brown, strigose, becoming glabrous. There is a thin purplish 
film of mycelium between the perithecia, which spreads 
beyond them over the substratum. I have not seen the 
conidia described by Berkeley and Broome. The asci are 
clavate, eight-spored, the sporiferous portion measuring 
160-175 X 16-20 ^ ; the spores are biseriate, or uniseriate 
below and in an irregular bundle above. The spores are 
fusoid in one aspect, elongated cymbiform in another, straight 
or slightly curved, 7-8 septate, not constricted at the septa, 
thin-walled, ends obtuse, black-brown, with the terminal 
loculi paler, 52-70 X 8-10 [k. Berlese’s classification appears 
to be correct.
