18 PETCH : 



Theissen and Sydow examined only a small part of the type 

 Bpecimen from Herb. Kew on Panicum trigonum, and found 

 that it bore a conidial fungus with hyaHne, acute spores. 

 15-18 X 2 ^. On the part of the type examined by me the 

 same conidial form was present, together with asci. The 

 stromata are oval, up to 0-6 x 0*4 mm. visible on both sides 

 of the leaf. The loculi contain hyaHne, continuous conidia, 

 which are fusoid, straight, or curved towards the ends, some- 

 times strongly attenuated towards one end, 18-26 x 2-2 "5 jjl. 

 The asci occur in the same loculi, and are 65-75 X 6 ^jl, eight- 

 spored, spores uni- or bi-seriate. The spores are hyaline, 

 continuous, with a central gutta, narrow-oval, ends acute, 

 13-14 X 3 '5-4 [x. This is evidently a Phyllachora, and will 

 stand as Phyllachora stenospora (B. & Br.) Sacc. 



239.— Dothidea Osbeckiae B. & Br. 



This was enumerated in Saccardo, Syll. Fung., II., p. 633, as 

 Dothidella. Theissen and Sydow (Ann. Myc, XII., p. 192) 

 have re-described it as Rehmiodothis Osbeckise (B. & Br.) 

 Theiss. & Syd. 



240.— Dothidea Elettarise B. & Br. 

 In Saccardo, Syll. Fung., II., p. 633, this was listed as 

 Dothidella. Theissen and Sydow (Ann. Myc, XIII., p. 408) 

 have re-described it as Placostroma Elettarise (B. & Br.) Theiss. 

 & Syd. It occurs on Amomum floribundwn Tr. = Elettaria 

 fioribunda Thw. 



241. — Dothidea incarcerata Berk. 



This was described by Berkeley in Hooker's Journal of 

 Botany, VI. (1854), p. 232. It occurred on leaves of Uvaria, 

 Guatteria, and other Anonacese. Berkeley stated that speci- 

 mens had been distributed under the name of Sph. Guatterise, 

 in the belief that they were distinct from those on Uvaria, 

 but further examination had forced him to unite them. 

 Cooke, on finding the specimen marked Sphseria Guatterise in 

 Berkeley's herbarium, published a description of it under the 

 name of Phyllachora Guatterise Berk. 



The specimens in Herb. Kew, in the cover of Phyllachora 

 incarcerata (Berk.) Sacc., include one, October 12, 1850, 

 labelled by Berkeley " Dothidea incarcerata Berk. {Sphseria
