In addition to tliose species recorded in a previous number of tliis
Journal, as having been recently detected by me in Great Britain, the
following have now to be enumerated. With two exceptions they
were gathered last autumn in the Highlands of Braemar and the
maritime tracts of Kincardineshire, and have been duly noticed by Dr.
Nylander in the ' Flora ' for 1868 and 1869.
1. Sj)ilonema Scoticim, Nyl. ; thallus black, forming small, compact,
convex, pulvinate patches ; apothecia black, very minute, the epithe-
cium impressed or convex ; spores 8 iu thecse, colourless, oviform-ob-
long, 1-septate, 0-010-14. mm. long, about 0-0045 mm. thick,
paraphyses discrete, slender ; epithecium vaguely obscure, hypotheciura
hymeneal gelatine blue with iodine.
On micaceous rocks of Ben Lawers, above Loeh-na-Cat. August,
colourless ;
1867. Kare, and but sparingly fertile. It is allied to -S'. revertens,
Nyl., but is suflniciently distinguished by the size of the apothecia, and
the character of the spores.
2. Collema Uchbiodeiim, Nyl. in litt. ; thallus linear-laciniated,
small, the laciuise obtuse and turgid at the apices, which are twice or
thrice divided ; the thallus iuternally nearly as in Ephebce, but with
different gonimia (although in colour almost corresponding), these being
small, and often joined in moniliform alveolse ;
apothecia unknown.
On schistose soil in crevices of rocks, and amongst decayed mosses
on boulders on the summit of Ben Lawers. August, 1863. This
somewhat peculiar species was first discovered by the late Rear- Admi-
ral Jones, and subsequently gathered by myself and j\Ir. Carroll. It
occurs in fair quantity, but without the least trace of apothecia, and
