Peradeniya, Dec, 1867 : sporidia 20 \i long, spermogonia 

 12 • 5 [i long." They also included Thwaites 499, on Urostigma 

 tomentosum, as a variety or a closely allied species, but made no 

 reference to any previous publication. The species, ex the 

 Fungi of Ceylon, was included in Saccardo under Phyllachora. 



In the cover of Phyllachora aspidea at Kew are three col- 

 lections. The earliest is marked " Sphseria aspidea on Ficus 

 repens, Ceylon, Oct. 12, 1850 " (not 1860 as cited by Theissen 

 and Sydow) ; this is the type. Another collection is Thwaites 

 423, marked " Dothidea aspidea Berk, cincta B. & Br. var., 

 on Ficus, Peradeniya, Dec, 1867." The third is Thwaites 

 499, marked with the same name as 423, on Urostigma tomen- 

 tosum, Feb., 1868. 



What Berkeley or Thwaites meant by Ficus repens is not 

 clear. Thwaites did not include Ficus repens in his Enume ratio 

 Plantarum Zeylanise. The " Ficus repens " of the Botanic 

 Gardens is Ficus pumila L., but the host plant in the type of 

 Dothidea aspidea is certainly not that species. The leaf is 

 identical with that of Thwaites 423, and appears to be Ficus 

 parasitica. 



Theissen and Sydow state that the epiphyllous species in 

 Thwaites 423 is scarcely different from the tjrpe, which they 

 name Catacauma aspideum (Berk.) Theiss. & Syd. It is on the 

 same host plant as the type, and is the same species. Thwaites 

 499 is regarded by them as a variety of Catacauma repens 

 (Corda). 235— Dothidea exsculpta Berk. 



This species was described by Berkeley in Decades 499a, 

 Hooker's Journal of Botany, VI. (1854), p. 231, from Ceylon 

 specimens on Agyneia multilocularis which were said to be 

 sterile. It was again recorded by Berkeley and Broome from 

 Thwaites 593 on Aporosa Lindleyana. In Saccardo it was 

 listed as Phyllachora. Cooke re-described it as Phyllachora 

 exsculpta Berk., in Grevillea, XIII., p. 64, without reference 

 to the host plant. 



Theissen and Sydow (Ann. Myc, XII,, p. 193) state that in 

 Herb. Kew there are Ceylon specimens on Aporosa Lindleyana, 

 Aporosa acuminata, Agyneia multilocuHaris, and a Phyllanthoid 

 plant. They have re -described it as ParmuUna exsculpta 

 (Berk.) Theiss. & Syd.
