     Thallus thin, crustose, with a parchment and felted appearance, whitish but becoming whitish-greyish in decay, sometimes, and then typically, spotted with orange (Trentepohlia). Apothecia 0.4-0.6 mm in diameter, at first more or less included in the thallus then more or less sessile, disc concave to plane, reddish, orange-brown, wine-red, translucent if fresh, becoming reddish-brown, brownish in old age, relatively thick concolor rim, persistent, sometimes with debris of the thallus when young. Utriform asci, with 12-48 spores, 80-105 x 15-25 µm according to our measurements. Acicular spores with tapered ends, 9-15 septa, 40-80 x 3-5 µm according to literature; 45-75 x 3-4 (5) µm and 10-16 septa according to our measurements. Photobiont: Trentepohlia. No significant color chemical reactions. Rare species found on the bark of old trees in oceanic forests. Cf. Cryptolechia carneolutea whose apothecia are more ochraceous, not translucent and less sessile.
