centre, each composed of minute, circular, or oval, close-set 

 depressed spots, with a raised margin, which bear clustered 

 or scattered pycnidia (?). These presumed pycnidia are 

 subepidermal, erumpent, globose, or sub-conoid, 110-140 \i. 

 diameter, 80-110 [l high, thick-walled. Apparently they are 

 all immature, and nothing resemblmg them has been collected 

 recently. 



Thwaites 448 bears the Nectria. In Herb. Kew the 

 specimen has by some confusion of numbers been labelled 445, 

 but its duplicates are correctly numbered 448. In addition 

 to the Nectria, the specimens bear a discomycetous fructifi- 

 cation ('? of a lichen) ; consequently part of Thwaites 448 

 was included in Ceylon Lichens as No. 339, but it was appa- 

 rently not named by Leighton. 



Nectria volutella is parasitic on a Meliola, which is covered 

 by its hyaline mycelium, thus forming the lichenoid white 

 crust noted by Berkeley and Broome. The perithecia are 

 scattered, depressed-globose, 0*25 mm. diameter, cream- 

 coloured, pruinose, naked in the upper third, but bearmg 

 spreadmg, rigid, hyaline hairs, up to 0'2 mm. long, in the 

 lower two-thirds. The hairs are thick-walled, about 5 ^ 

 diameter, septate, tapermg to the apex. The asci are clavate, 

 thick-walled, shortly pedicellate, 160 x 20 \i, eight-spored, 

 spores biseriate. The spores are hyaline, narrow-oval or 

 lanceolate, three to five septate, 32-36 x 7-8 ^. 



This species was transferred to Calonectria by Saccardo, in 

 Michelia, I., p. 309. Cooke listed it as Lasionectria in Grevil- 

 lea, XII., p. 112, and noted that the spores were two to five 

 septate. 



Nectria trichospora B. & Br. 



This species was described by Berkeley and Broome in 

 Fungi of Ceylon, No. 1014, as " Peritheciis ovatis elongatis 

 asperis coccineis ; ascis clavatis, sporidiis fusiformibus 

 longissimis multiseptatis. Sporidia 225 \x long." It was said 

 to be Thwaites 29, and 647 in part ; as in other cases, 647 is 

 part of Thwaites 29. The specimen in Herb. Peradeniya is 

 marked 1104 (29 part) ; it contains N. trichospora and Nectria 

 hsematococca.
