which in some cases appears almost black. The wall appears 

 pruinose, its outer layer being composed of loosely interwoven, 

 thick-walled, often irregular hyphse, collected here and there 

 into loose masses. The asci are cylindric, sessile, eight-spored, 

 with obliquely uniseriate spores, about 50 x 6 jjl. The spores 

 are oval, hyaline, not, or slightly, constricted at the septum, 

 sometimes attenuated towards one end, minutely rough, 9-13 

 X 4-5 (X. 



The type specimen in Herb. Kew is too ripe to show asci, 

 but they are evident in the co-type in Herb. Peradeniya. von 

 Hohnel (Mitt. XIV., p. 20) writes that he was unable to 

 confirm Starback's statement that the spores are rough ; 

 they are rough in the perithecium from the type examined 

 by me. 



Hypoxylon umlbrinellum B. & Br. 



This was described in Fungi of Ceylon, No. 1075, as " Late 

 efEusum ; peritheciis minutis ovatis metulaeformibusque 

 umbrinellis materie furfuracea vestitis ; ascis linearibus ; 

 sporis subellipticis, imiseptatis, demum echinulatis (No. 1111). 

 On dead wood with Byssisedse. Margin of the stroma often 

 barren, as in H. rubiginosum ; sporidia 12*5 by 6*25 ^." In 

 Saccardo, I., p. 729, it was listed, with a query, as Amphis- 

 •phseria. 



In the CO -type in Herb. Peradeniya the perithecia are quite 

 separate from one another, but crowded side by sitle in a flat 

 layer, with a slight basal layer of mycelium. They appear 

 dark brown or blackish-brown, but the wall when mounted is 

 yellow-brown to rerd -brown. They are ovoid, 0*3 mm. 

 diameter, and 0'4 mm. high, with a papillate ostiolum, prumose. 

 The wall is composed of rather large thin-walled cells, and 

 is rough with slightly projecting cells and small scattered 

 warts. The asci are clavate, sessile, eight-spored, with 

 obliquely uniseriate spores, 60-70 x 8 [ji,. The spores are 

 elliptic to fusoid, ends obtuse, one-septate, occasionally 

 constricted, pale brown, wall striate with coarse ridges which 

 are often broken, 11-15 X 5-6 [ji. 



In Ann. Perad., VI., p. 345, this species was transferred 

 to Phseonectria. Cooke, however, had previously discovered
