CEYLON rUNGI. 13 



composed of polygonal cells, sometimes radially arranged 

 towards the .margin, and the margin is sometimes lobed. 

 The asci are ovate, eight-spored, 38-^0 X 21 [x. The spores 

 are hyaline, oblongo-fusoid, one-septate, slightly constricted at 

 the septum, ends rounded, minutely veiTUcose, 15-17 x 6-7 \i, 

 the upper cell usually the broader. This species apparently 

 belongs to the Munkiellise, near Isomunkia, but it has no 

 paraphyses. 



The specimens on Acrotrema and Jasminum Sambac have 

 not been found. 



229. — Asterina nubecula B. & Br. 



This name was published by Berkeley without description 

 in Hooker's London Journal of Botany, VI. (1854), p. 211, 

 but the species was not described until the publication of the 

 Fungi of Ceylon. The type has been examined by Theissen, 

 and re-described under the name of Calothyrium nubecula 

 (B. & Br.) Theiss. (Ann. Myc, X., p. 192). 



230. — Asterina Pleurostyliae B. & Br. 



The type of this species, Thw. 470, has been re-examined by 

 von Hohnel, who finds that it is a Meliola, Meliola Pleurostylise 

 (B. & Br.) V. H. (Fragm., X., No. 522). It was made the type 

 of a new genus, Asterid'him, by Saccardo in Syll. Fung., IX., 

 p. 435. 



In Herb. Kew there are two Ceylon specimens in the cover 

 of Asterina Pleurostylise. One, on Pleurostylia, is the Meliola ; 

 the other, on Pavetta, is Lembosia Pavettda Theiss. 



231. — Dothidea demersa Corda. 



Under this name Berkeley and Broome placed Thwaites 464 

 on Ixora parvifolia, and Thwaites 520 on Croton Thwaitesianum 

 Mull. = Croton Klotzschianus Thw. Ixora parvifolia should 

 be Ixora parvifiora Vahl. According to Theissen and Sydow, 

 no type of Dothidea demersa Cda. exists. The specimen on 

 Ixora parviflora has been named by them Phyllachora Ixorae 

 Theiss. & Syd., but they give the locality as East Indies, 

 collected by Hobson, though they cite the number 464, which 

 is Thwaites's (Ann. Myc, XIII., p. 553). The specimen on 

 Croton in Herb. Kew is sterile, according to Theissen and
