In 1873 Berkeley and Broome published the second part of 
their Fungi of Ceylon, and included descriptions of two 
species of Tri^hragmium, viz., T. Thwaitesii and T. claveMosum, 
as follows : — 
‘‘ 822. Triphragmium Thwaitesii B. & Br. Sporis globosis, 
processibus bifurcatis ornatis. On leaves of Hedera VaMii, 
Peradeniya, April, 1861. 
“ 823. Triphragmium clavellosum B. in Gard. Chron., 
1857. Sporis obovatis, processibus apice emarginatis ornatis. 
On Paratrope terehinthacea. At first obovate, simple, then 
divided by a horizontal septum ; the upper articulation 
divided into two vertically. Spots on Hedera and Paratrope, 
broad and diffuse ; in the Canadian specimens much narrower.” 
Here the confusion begins. Triphragmium Thwaitesii 
B. & Br. is the species which Berkeley regarded in 1865 as a 
variety of T. echinatum ; it is described here for the first time. 
The name Triphragmium clavellosum had been published 
previously, but v/ith scarcely anything that could be called a 
description, and it might be claimed tha.t this is the first 
publication of that species also. In any case this description 
is based on Ceylon material (on Paratrope), and it is the first 
occasion on which the name of a host-plant is given with 
certainty. Berkeley further confuses matters by referring to 
both Hedera and Paratrope under T. clavellosum, though he 
had named the species on Hedera T. Thwaitesii. However, 
this last point is immaterial, so far as Ceylon is concerned, 
since Hedera Vahlii and Paratrope terehinthacea are synonyms. 
There can be no doubt whatever that the records of these two 
species of Triphragmium in the Fungi of Ceylon refer to the 
same fungus on the same host -plant. The questions to be 
decided are, Is the Ceylon species identical with the Canadian 
species named in 1857, and, if so, is it to be called T. clavellosum ? 
In Grevillea, III., p. 55 (September, 1874), Berkeley again 
described Triphragmium clavellosum: — “ Soris in maculas 
orbiculares congestis epidermide cinctis nigris ; sporis truncato- 
obovatis biseptatis ; septo superiore verticali, processibus
