his measurement of the spore is 10 x 6 [l, while Cooke's is in 

 millimetres, and is consequently 16 X 8 jj,. The ascus 

 measurement is not in accordance with Cesati's declared 

 practice, and would appear to be in decimals of an inch, 

 following the example of Berkeley and Broome. 



Cooke, in Grevillea, XII., p. 110, referred this species to 

 Cosmospora (as a subgenus). 



There is a specimen from Cesati in Herb. Kew. The 

 perithecia are scattered or crowded, superficial, without a 

 stroma, ovoid, about 0*25 mm. diameter, collapsing, orange- 

 red, pruinose. The perithecial wall is composed of large cells, 

 about 10 [L diameter, and bears loosely -built, small warts of 

 large cells, or scattered isolated projecting cells. The asci are 

 eight-spored, cylindric, with spores uniseriate or obliquely 

 uniseriate, 90-110 x 8-10 [>.. The spores are oval, one- 

 septate, not constricted at the septum, ends obtuse or subacute, 

 brown, coarsely verrucose with warts and short ridges 

 arranged in longitudinal lines, 10-16 X 5-8 \l. ' 



Cooke's reference to. Cosmospora is consequently correct. 



Nectria tabacina Ces. 



This species was collected in Ceylon by Beccari and 

 described by Cesati. The description is " Perithecia minutis- 

 sima, conferta, obovata, ostiolo acuto, demum f usco-ochracea, 

 collapsa. Asci nulli adsunt, sed tantum sporidia oblonga, 

 00025, obscure septata ?, hyalina. Ad Polypori ? frustula. 

 Nectriae pezizx haud dissimilis. Vix N. suffulta B. & Br." 

 Cooke, in Grevillea, XII., p. 110, included it under Eu-dialo- 

 nectria without comment. There is a specimen from Cesati in 

 Herb. Kew. It is listed in Saccardo as Nectria, the spores 

 being given as 25 [i, long. 



In the specimen in Herb. Kew the host is not a fungus, but 

 the wall of some fruit, apparently a mangosteen {Garcinia 

 mangostana). The perithecia are superficial, gregarious, about 

 0*4 mm. diameter, dark red, pruinose with yellow granules, 

 globose, with a conical ostiolum, collapsing. The perithecial 

 wall is composed of large thin-walled cells, tangentially 

 elongated and circularly arranged round the ostiolum. 

 Among the perithecia are a few dark red, stout hyphse (?) up
