LICHENS OF THE ISLE OF MAN. 
Verruearia maura (Whlnb.). Black, smooth, continuous, covered with 
minute cracks, somewhat shining; apothecia wholly immersed in 
thallus, forming hemispherical points, with a minute hole on the top. 
Spores 8, colourless, oblong, simple; sometimes pale, granular, 
•012 x ’007 mm. Like inkstains. On rocks on the shore, Peel. 
V. 
epidermis (Ach.). 
Pale yellow, very 
thin, smooth and 
shining; apothecia 
black, scattered, 
minute, almost 
buried in little 
cones of the 
thallus; paraphy- 
ses very few. 
Spores 8, colour¬ 
less, 1-septate, 
constricted in the 
middle. On birch 
trees. Ramsey. 
Young: Ascus, 
with Spores 
and Paraphyses. 
•015 to ‘02 m. long x -006 to -01 mm. 
wide. Spermatia ‘006 x ’001 mm. 
V. terebrata? (Mudd.). Slaty grey, 
continuous, smooth, broken by 
minute cracks; apothecia black, 
deeply immersed in thallus; 
paraphyses distiuct and slender. 
Spores 4, brown, oval, built up

Explanations. 
In the foregoing list the thallus is described first, next the apothecium, then 
the spores, followed by any other information. 
The place and habitat is given where each specimen was found, and they 
would probably be found in similar situations in other parts of the 
Island. 
Colour reaction : — K. represents Hydrate of Potash ; C. represents 
Hypochlorite of Lime; tested by a drop from a glass point, placed 
upon tbe surface of the thallus. The medulla, which is white, is tested 
in a similar manner, after removing a small portion of the epidermis 
(or skin) of the thallus. 
I should be pleased to receive further notes or information, or to 
see any specimens of Lichens from the Isle of Man.
