apice incrassatis emarginatis asperis . — Gard . Chron .,1857. On 
leaves apparently of Amygdaleæ. St. Lawrence. No. 5467, 
Montreal, Dr. Maclagan. Fornxing orbicular black patches ; 
sori surrounded by the cuticle. Spores at first oblongo- 
ovate, even, then truncate -ovate, with one horizontal and one 
vertical division, rough with clavate processes emarginate at the 
tips.” This is the description cited in Saccardo, VII., p. 770, 
with the addition, ‘‘ in foliis Araliae nudicaulis, Paratropæ 
terebinthaceæ, Hederæ, et Amygdaleaceæ cujusdarn in America 
boreali et in insula Ceylon.” It would appear that this de- 
scription of Berkeley’s is merely a repetition of the original 
American record, with details added from the Ceylon specimens. 
In the Journal of Mycology, VI., pp. 123, 124, F. W. 
Anderson re-describes these two species. He states ; “ In 
Saccardo ’s Sylloge, VII., p. 770, are given brief descriptions 
of Triphragmium clavellosum Berk, and Triphragmnim 
Thwaitesii B. & Br. The former occurs in America on Aralia 
nudicaulis, and is said (/. c.) to occur also in Ceylon on Para- 
trope terebinthacea, Hedera, and Amygdaleæ species. The 
latter is given for Ceylon as occurring on Hedera Vahlii, and 
the question is asked whether it is not the same as T. clavello- 
sum. I have not been able to secure Ceylon specimens 
referred to T. clavellosum, but it is quite likely that all such 
are referable to T. Thwaitesii. Of this latter, I have secured 
an authentic specimen from Mr. J. B. Ellis, to whom it was 
sent by Dr. M. C. Cooke, of London, England. As T. clavello- 
sum and T. Thwaitesii are related species, it is easy to under- 
stand why confusion should arise concerning them, especially 
when we consider the meagre published descriptions in which 
spore measurements are entirely omitted. T. Thwaitesii is a 
quite distinct species from North American forms of T. 
clavellosum, and it is pretty safe to say that T. clavellosum is 
American, and that T. Thwaitesii is Asiatic.” 
The above comnxunication seemed to have decided at least 
one of the points at issue, viz., the question of the identity of the 
two species, though Anderson is in error in referring the record 
on Amygdaleæ to Ceylon. The Ceylon fungus grows on 
Heptapleuron stellatum (= Hedera Vahlii = Paratrope tere- 
hinthacea) ; the cherry record is American. A few years later
