occurs in some abundance on dead leaves of Amomum 
Hakgala. It is lemon-yellow, cylindrico-campanulate, pen- 
dent, up to 4 mm. long and 2 mm. diameter, affixed by a short 
curved stalk, or almost sessile, membranous, pale within, 
minutely tomentose ; the mouth is fimbriate and straight ; 
the stalk is up to 0 * 3 mm. long and 0 • 15 mm. diameter. 
Berkeley and Broome cite Thwaites 98 as the type, and state 
that Thwaites 99 is a little darker. Both specimens are in 
Herb. Peradeniya. Thwaites 98 contains specimens on bark 
and also on a leaf, perhaps two different species. Thwaites 
99 contains another species with an evident basal mycelium, 
which is absent in the case of the species on the leaf for which 
the name has here been adopted.

Triphragmium Thwaitesii B. & Br. 
In an article on Vegetable Pathology, No. CXLVIII., in the 
Gardeners’ Chronicle, 1857, p. 21, Berkeley included a 
paragraph on Triphragmium, in which he wrote : I now 
figure two additional species, T. degluhens and T. clavellosum, 
the latter of which grows apparently on some cherry, and is 
remarkable for the forked processes with which it is sparingly 
clothed, and the rather long hyaline stem. Léveillé’s species 
on Meum, like this, has spinulose processes, and like the former 
of them parallel dissepiments.” The rough figure is labelled 
“ Triphragmium clavellosum Berk, from Montreal.” 
In the same journal, 1865, p. 196, Berkeley returned to the 
subject of the genus Triphragmium, and after describing 
T. echinatum Lév., wrote : At a later period Mr. Thwaites 
forwarded to us from Ceylon a parasite on a species of Hedera 
(H. Vahlii), agreeing with the parasite on Meum in every 
particular, as Mr. Broome has observed, except that every 
process is either bifid or trifid, the short divisions being 
strongly recurved, whereas in M. LéveiUé’s plant, the spines, 
if forked, have the divisions much shorter and not in the 
least reflexed our plant may be regarded, then, as a 
marked variety of Triphragmium echinatum, characterized by 
the re-curved divisions of the spines, and may bear the name 
of T. echinatum var. Thwaitesii. The diameter of the spores,
