Ochrolechia androgyna  Taxon saxicole maritime.

Synonyms:

Family: OCHROLECHIACEAE

Habitat: Aerohaline zone

Description

    Thallus crustose, thick, wrinkled, cracked, markedly verrucose, warts rounded, white-yellowish, pale grey-yellowish, more or less covered with piles of soredia, rounded and convex, yellowish, grey-yellowish, potentially covering important sections, prothallus whitish. Most often sterile, but fertile specimen may be observed notably in the islands West of Brittany with scattered apothecia, 2-5 mm diam., disc concave, orange, yellow-orange, exciple markedly sorediate. Asci in club, 110-130 x 40-50 µm with 8 spores. Simple, ovoid, colorless spores but a little graying in old age and a granular content in optical section, 30-45 x 12-20 µm according to the literature, 28-50 x 15-25 µm according to our measurements. C + scarlet, K +/- yellow then orange, KC + red, P-. Photobiont: Chlorococcoid.  This taxon is restricted to seashore habitats and it has been observed only on very exposed rocks in the aerohaline zone of heads, capes and islands of Western Brittany. Not to be confused with some forms of Pertusaria pluripuncta that share the same habitat and of which the thallus is devoid of soredia, with larger warts, and K+ yellow,  C+ orange, Pd+ red-orange. See Lecanora poliophaea whose colored chemical reactions are negative.

N.B. This very particular taxon deserves to be separated (and renamed) from Ochrolechia androgyna which is a collective species.
