Notes on New or Rare British Fungi. Malcolm Wilson. 85 
The specimens from Arran collected in the spring show typical 
Melasmia conidia similar to those described by Magnus and no 
trace of asci and it is evident that Melasmia Empetri has no 
connection with any species of Rhytisma. 
There is little doubt that Rhytisma Empetri Buchanan White 
is identical with Melasmia Empetri Magn. In the description 
of White’s specimens given by Berkeley and Broome (Annals 
and Mag. of Nat. Hist. vol. xvi, 1876, p. 129) no mention is 
made of the spores but the asci are described as straight and 
immature; these were probably the sporophores. Three speci- 
mens of Rhytisma Empetri collected by White are preserved in 
the Kew Herbarium but these are sterile and contain only 
sporophores of the Melasmia type. There is one specimen in 
the British Museum herbarium collected by D. Hay probably 
in Perthshire and named apparently by Broome but this con- 
tains no asci. Mr D. A. Boyd informs me that he has collected 
specimens of R. Empetri White near Largs, Ayrshire, and also 
from Creag na Caillich, but has never found asci developed in 
them. The late Prof. Trail considered that R. Empetri White 
might be the same as M. Empetri Magn. (Scot. Nat. vol. 01, 
n.s. 1881-1888, p. 235). Juel, who has recorded Melasmia 
Empetri Magn. in Sweden (Mykologische Beitrage. II. Ofvers. 
Kongl. Vet.-Akad. Férh. No. 9, 1894, p. 502) points out that 
it resembles Rhytisma Empetri White fairly well in external 
appearance. Stevenson (Mycologia Scotica) states that R. Em- 
petri White is found in the Tay, Dee, and Moray areas and at 
Inverness, Rannoch, Braemar and N. Wales. White records it 
as common in Breadalbane, Athole and Rannoch. No further 
information regarding its occurrence in N. Wales has been 
found. 
Rhytisma Empetri Fr. (Duplicaria Empetri Fuck.) is a different 
species and has not been recorded as British. 
Botrytis DouGtLasi Tub. 
On living shoots of Pseudotsuga Douglasii Carr., Murthly, 
Perthshire; on seedlings of Pseudotsuga Douglasii Carr. near 
Forfar, and on seedlings of Larix leptolepis Endl. near Edin- 
burgh. Collected by Mr J. M. Murray, October 1920. This has 
been shown by Behrens to be identical with Botrytis cinerea 
Pers.; it does not appear to have been recorded previously on 
these hosts in this country. 
I wish to record my thanks to Prof. Ferdinandsen of Copen- 
hagen for specimens of Hypodermella sulcigena and the Director 
of the Royal Gardens, Kew, Mr D. A. Boyd, and especially 
Mr J. Ramsbottom of the British Museum (Natural History) 
for information regarding several of the above species.
