ostiola, which are furnished with periphyses. The asci arise 

 from the base of the loculus ; they are clavate, very shortly 

 pedicellate, thick-walled, the apex up to 12 [k thick, eight- 

 spored, with the spores four-seriate, 75-90 x 16 [x. The spores 

 are hyaline, narrow-fusoid, slightly curved, one-septate, not 

 constricted, 43-56 X 3-4 \x. From the holes in some of the 

 leaves, it would appear that the stromata ultimately fall out. 



I have not been able to find the paraphyses recorded by 

 Berkeley and Broome. Nor is it possible to confirm Theissen 

 and Sydow's statement that the stroma is covered by an alga 

 layer, embedded beneath the cuticle. Some alga cells are 

 present on the exposed part of the stroma, but they do not 

 appear to extend beneath the cuticle, and they are not present 

 on the young stroma, which, indeed, develops in the mesophyll 

 below the epidermis. In the case of a coriaceous leaf like that 

 of Calophyllum Walkeri, grown in a very moist climate, it is 

 not exceptional to find algse in cracks in the leaf or distributed 

 over its surface. Indeed, it may be regarded as the rule 

 rather than the exception. This species would appear to 

 agree with Dothidella, and will stand as Dothidella CalophylU 



(B. & Br.). 248.— Dothidea dolichogena B. & Br. 



This was included in Saccardo, Syll. Fung., II., p. 601, as 

 Phyllachora dolichogena (B. & Br.) Sacc. Theissen and Sydow 

 confirm this. The specimen was said to be on leaves of Dolichos, 

 but it may be noted that Thwaites queried that identification 

 of the host on the co-type in Herb. Peradeniya. 



249. — Dothidea calamigena B. & Br. 



Saccardo, Syll. Fung., II., p. 606, placed this species in 

 Phyllachora. Theissen and Sydow have re-described it, from 

 the type specimen, as Phseochora calamigena (B. & Br.) Theiss. 

 & Syd. It occurred on Calami^ rudentum Moon = Calamus 

 zeylanicus Becc. 



250.— Dothidea niicina Mont. 



In Decades of Fungi, No. 499 (Hooker's Journal of Botany, 

 VI. (1854), p. 232), Berkeley described a Ceylon specimen as 

 Dothidea filicina Mont. MSS., var. nervisequia, on the under- 

 side of fern leaves. In the Fungi of Ceylon, No. 1170, the 

 record appears as " Dothidea filicina Mont. On leaves of ferns,
