NOTES ON THE BRITISH SPECIES OF CAMPYLOPUS. 
By H. N. Dixon, M.A., F.L.S. 
C. pyriformis Brid., var. Miillert (C. Miileri Jur.).—I find this 
form at Kingsthorpe, Northamptonshire, with the calyptra quite 
entire at the base, or, in a very few cases, very slightly lobed indeed. 
Leaves very deciduous ; in the type are rarely so, I think, to 
any great extent in the fertile plants, though the condition is a 
very prevalent one when barren. 
C. fragilis B. & 8.—In fruit, Poison Glen, Donegal, 1890.—A 
d at Ecclesbourne, near 
stem tomentose above in CU. Schimpert, with copious radicles even 
tus the s 
la 
large hyaline cells, C. Schimpert having only a single row of these 
cells; (5) the presence or absence of basal auricular cells; (6) the 
impert. 
value of the character derived from the tomentose con- 
dition of the stem, as well as that of the relative size of the plants, 
ig minimised by the fact that in the var. elongatus Bosw. of C. subu- 
latus, which attains to one or two inches in height, the stems 
(though not the branches) are described as “ copiously radiculose 
below.” Specimens of C. Schimpert, moreover, gathered in 1890 
in the north of Ireland (for the correct naming of which I have the 
authority of Mr. H. Boswell and others), have the stems entirely 
d t 
C. Schimperi is constantly the broader, is far less than is often seen 
in leaves, even in those taken from the same plant, of C. fragilis or 
f C. fleauosus. 
(4). I do not think much weight can be attributed to this char- 
acter. Specimens of VU. Schimperi. from Rabenhorst’s exsiccata 
show the anterior row of hyaline cells to be here and there 
doubled; while in authentic specimens of C. subulatus from Fern, 
near Brechin, I find this stratum to be distinctly composed of a 
single row, with two rows of small opaque cells at the back, and the 
same is the case with plants of the same species gathered in 
Belgium by Gravet.
