Lecidella carpathica is characterised by: the saxicolous habit; the grey-white, minutely granular to areolate thallus without a delimiting prothallus and often obscured by crowded apothecia; the numerous sessile, 1–6-confluent, black epruinose apothecia, with persistent, flexuous–contorted margins, concolorous with disc; the brown-black hypothecium; the green-black to blue-black epithecium; ellipsoidal ascospores (8–)10–12(–15) × 5–8.5 μm; and a chemistry comprising thuringione, diploicin, chloratranorin and 4,5-dichlor-3- O -methylnorlichexanthone (KC+ orange). Recorded in 19th century accounts as Lecidea parasema var. latypea and as Lecidea latypiza (e.g. Nylander 1866b, 1888; Lindsay 1866b).
