CEYLON FUNGI. 
175 
diameter, depressed globose, minutely adpressed hairy, black- 
brown, embedded in a dense weft of purple-brown mycelium ; 
the ostiolum is small, conical, black, and glabrous. The spores 
are narrow-oval, ends rounded, subcymbiform in one aspect, 
with a thin hyaline coat, 28-38 X 8-11 They do not at all 
agree with Berkeley and Broome’s description“ sporidiis fusi- 
formibus acutissimis,” which fits the parasitic species far better. 
I have what I take to be the same species from Hakgala, 
but in that gathering the perithecia are not depressed. The 
adpressed hairy covering, derived no doubt from the surround- 
ing mycelium, weathers off, and the perithecia become black. 
The spores of this collection are 24-32 x 9-13 ^ : they are the 
same shape as in the type, and, like those of the latter, are 
uniseriate in the ascus. 
The species which we have hitherto referred to R. hoihrina 
was collected by Thwaites (219), but was assigned by 
Berkeley and Broome to Rosdlinia aquila Fr., from which it 
differs completely. Indeed, it differs so much that one is 
inclined to suggest that Berkeley and Broome confused their 
numbers, and that Thwaites 299 should have been Rosellinia 
aquila (which it resembles), and Thwaites 219, which the brief 
description fits, Rosellinia hoihrina. As this species (Thwaites 
219) does not appear to have been named, it may be known as 
Rosellinia arcuata n. sp. A full description was given in 
Ann. Perad., IV., pp. 433, 434, under Rosellinia hoihrina. 
Rosellinia arcuata. — Peritheciis gregariis, primo in mycelio 
purpureobrunneo immersis, fuscobrunneis, deinde nigris, 
liberis, carbonaceis, globosis, leniter depressis, 1*5-2 *4 mm. 
diam., levibus, ostiolo conico, 0*1 mm. alt., basi 0*4 mm. 
diam. oriundo. Ascis cylindraceis, 300 ^ long., 8 diam., 
sporis oblique uniseriatis ; paraphysibus circa 2 ^ diam., ascos 
æquantibus. Sporis nigris, cymbiformibus, apicibus acutis 
et sæpe subito contractis, 30-47 x 5-7 
131, — Rosellinia catervaria (B. & Br.) Sacc. 
This species was sent by Thwaites, mixed with Bomhardia 
Janus, and was described by Berkeley and Broome under the 
name of Sphæria (denudatæ) catervoHa B. & Br., Fungi of 
Ceylon, 1104.
