by H. sulcigena bear brownish-black blotches or zones which 
are considerably larger and darker than the diseased areas pro- 
duced by H. pinicola. The darker colour of the former species 
is produced partly by the hyphae in the leaf tissue which are 
up to 6m in diameter and pale brown in colour and partly by 
the brownish discolouration of the leaf tissue, especially the 
hypoderma. In the description of H. sulcigena given by Rostrup 
(Undersogelser over Snyltesvampes Angreb paa Skovtraerne. 
P. E. Muller’s Tidsskrift for Skovbrug, Bd. vi, 1883, p. 199. 
Ref. Bot. Centralbt. Bd. xv, 1883, p. 151), the measurements 
of the asci are given as 75-85 x I2m and the ascospores 
30-40 xX 4; there are only four spores in each ascus. If these 
measurements are constant there are evidently considerable 
differences between the two species. In addition the mucilage 
surrounding the ascospores is stated to stain bright green with 
tincture of iodine in H. sulcigena while this is not the case in 
H. pinicola. 
HYPODERMA BRACHYSPORUM (Rostr.), Tub. 
On leaves of Pinus Strobus var. nana, Knight. Murthly, 
Perthshire, April 1920. Not previously recorded for Britain, 
but widespread on the continent. 
Puccin1A MILLEFOLi Fuck. 
On Achillea Millefolium L., Epsom Common, September 1919. 
PUCCINIA PAZSCHKEI Dietel. 
On Saxifraga longifolia Lapeyr., S. Hostit Tausch. and its 
var. rhaetica and on S. Aizoon Jacq. var. cultrata, Royal Botanic 
Garden, Edinburgh, September 1920. 
The sori are usually on the upper surface toward the apex of 
the leaf, occasionally on the under surface, rounded, up to 
3mm. diam.; a large sorus is often surrounded by a ring of 
small ones. At first the portion of the leaf around the sorus is 
yellowish; later on dark brown irregular patches of dead tissue 
are produced which extend through the thickness of the leaf. 
Teleutospores 32-38 x 17-20. Previously recorded at Kew 
on Saxifraga longifolia, at Sutton Coldfield on the hybrid 
S. Cotyledon x S. Aizoon and in Switzerland and Austria on 
S. Hostit. 
PUCCINIA GENTIANAE Link. 
Teleutospores on Gentiana verna L. and G. acaulis L.; col- 
lected by Mr D. Hendry, Llanisten, near Cardiff, Oct. 1920. 
This species has not been previously recorded on G. verna 
in Britain. Plants of Gentiana asclepiadea L. growing in close 
proximity were not diseased although this species is attacked on 
M.S. 6
