Tn addition to those species recorded in a previous number of this 
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. 
l. Spilonema Scoticum, Nyl. ; thallus black, forming small, compact, 
convex, pulvinate patches; apothecia black, very minute, the epithe- 
cium impressed or convex ; spores 8 in thecze, colourless, oviform-ob- 
long, l-septate, 0°010-14 mm. long, about 0:0045 mm. thick, 
paraphyses discrete, slender ; epithecium vaguely obscure, hypothecium 
colourless ; hymeneal gelatine blue with iodine. 
On micaceous rocks of Ben Lawers, above Loch-na-Cat. August, 
1867. Rare, and but sparingly fertile. It is allied to S. revertens, 
Nyl., but is sufficiently distinguished by the size of the apothecia, and 
the character of the spores. 
Collema lichinodeum, Nyl. in litt.; thallus linear-laciniated, 
small, the lacinize obtuse and turgid at the apices, which are twice or 
thrice divided ; the thallus internally nearly as in Ephebe, but with 
different gonimia (although in colour almost corresponding), these being 
small, and often joined in moniliform alveole ; 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 Mr. Carroll. It 
oceurs in fair quantity, but without the least trace of apothecia, and
