Lecanora soralifera (Suza) Räsänen


Thallus grey or greenish grey, of scattered to aggregated, flat, crenulate-margined areoles, conspicuously and abundantly sorediate, the soredia pale yellow and arising in rounded, convex soralia from the areolar surfaces; apothecia uncommon or inconspicuous, often arising from areoles that lack soredia, discs translucent, variable in colour, greenish, pink-brown, brown-grey or dark grey, smooth and appearing waxy. Widespread but tending to be upland, on siliceous rocks and walls.

Refs: Smith et al. (2009), 497; Purvis et al. (1992), 315; Dobson (2005), 231 (photo); Dobson (2011), 233-4 (photo, poorly printed); Wirth (1995), 1: 453, 487 (photo); Wirth, Hauck & Schulz (2013), 1: 577, 612 (photo).

Confusing when apothecial states occur with or even intermixed with L. intricata, but the apothecia are noticably smaller and some of the areoles may be seen to bear both apothecia and sparse soredia.
