Recorded by W. G. Travis on decayed moss. The condition of the 
margin seems, however, to be merely a growth phase that occurs in 
plants on limestone as well as in those on mosses. 
Hab. On mosses or mortar of an old limestone wall at Downham, 
Lancashire. 
4a. Gyalecta rubra Massal. Ric. Lich. Crost. p. 146 (1852).— 
Thallus effuse, thin, powdery or granulose, whitish, the hypo- 
thallus whitish, scarcely visible (K —). Apothecia moderate in 
size (rarely up to 1:5 mm. across), at first closed then open and 
concave, the disc rosy-red or reddish flesh-coloured, sometimes 
slightly pruinose, the outer margin prominent, persistent, crenu- 
late ; paraphyses stoutish, septate, clavate and red at the tips ; 
spores oblong-ellipsoid, 3-septate, 15-23 yp long, 5-8 p thick.—

Forming a thin widely effuse scurf on the substratum of bark or” 
moss. The apothecia are numerous and prominent and well marked 
‘by the white crenulate margin and the rose-red disc. 
Though classified by various lichenologists under Lecanora, the 
structure of the thallus (with Trentepohlia gonidia), and of the 
apothecia, agree with the Gyalectz. The species should be inserted 
after G. geoica. (Part 2, p. 7.)

walls, &¢.—Dzstr. Local or rare in §., W. and N. England and in the
