Anzina carneonivea (Anzi) Scheid.

Syn. Varicellaria carneonivea (Anzi) Erichsen

Crustose lichens containing a trebouxioid alga; thallus smooth or cracked, creamy-white or bluish white, rarely producing granular soredia in round soralia; apothecia often clustered, numerous, 0.15-0.3 mm wide, with a thin but persistent thalline rim and a pale tan disc; hymenium formed of gnarled, branched and anastomosing paraphyses embedded in gel; asci thin-walled, IKI- or + pale blue; spores 4 or 8 per ascus, colourless, ellipsoid to fusiform, variably 1- to 3-septate, 10-20 × 5-8  µ.

Reactions: Apothecial discs C+ reddish (flash), K+ faint yellow.

Contents: Gyrophoric acid, lecanoric acid in small amounts, unknown substances.

Habitat: On acidic bark of shrubs and conifers, wood of decaying logs, and duff, always within the winter snowpack, and only at upper forested elevations.

Similar Species: Outwardly like Pertusaria carneopallida, which differs in having larger, more scattered apothecia and simple spores.

Specimens: Björk 12896.

Local Status: Common (at least var. tetraspora).

Notes: Two varieties have been observed in the study area, as follows:
