in Nimis et al., MycoKeys 31: 10, 2018. Basionym: Pertusaria erumpens Erichsen - Acta Faun. Fl. Univers., Ser. 2, Bot. 1, 17: 1, 1935.

Synonyms:

Distribution: N - Lig.

Description: Thallus crustose, episubstratic, rather thin, finely rimose to irregularly fine- warted, pale to dark grey, sometimes delimited by a thin, black prothalline line. Soralia small, 0.2-0.5 mm across, at first punctiform, then small-maculiform and more or less orbicular, often delimited by a raised thalline margin, finally sometimes confluent, moderately convex, yellowish white, with coarsely granular soredia. Apothecia unknown. Photobiont chlorococcoid. Spot tests: thallus K+ yellow, C-, KC+ yellow then brownish yellow, P-, UV-; medulla and soralia K+ yellow-brown, C-, KC+ pale yellow-brown, P+ orange-red. Chemistry: medulla and soralia with fumarprotocetraric acid (major), and variable amounts of protocetraric acid.

Note: a very poorly known taxon of siliceous rocks, also reported from Romania and Austria, related to L. aspergilla, reported from Liguria. The indicator values are tentative.

Growth form: Crustose

Substrata: rocks

Photobiont: green algae other than Trentepohlia

Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
