Lecanoropsis calabrica Ivanovich & Printzen 2025, comb. nov.

Lecanoropsis calabrica (M. Brand & van den Boom) Ivanovich & Printzen, comb. nov. MycoBank nº: 847143 Basionym: Lecanora calabrica M. Brand & van den Boom, in van den Boom & Brand, Lichenologist 40 (6): 470 (2008). Type:— ITALY, Calabria: Sila Grande, Lago Arvo, 1 km NE of Barachella, 1200 m alt., 39°14’ N 16°29’ E, 14 May 2001, Brand 42986 (LG— holotype; hb. Brand— isotype; not studied). Description: see van den Boom & Brand (2008) Notes: The description provided by van den Boom & Brand (2008) indicates some similarities with Lecanoropsis subravida. However, the apothecial margin of L. calabrica is thin, whereas L. subravida develops a thick, prominent and knobbly margin. Another difference is the length of ascospores, with those of L. calabrica being slightly shorter (8.4–9.6 µm) than those of L. subravida [(7.5–)8.5–11.9(–13.5) µm]. Macroconidia were not reported for L. calabrica, only leptoconidia, which are longer (22–27 µm) than those of L. subravida (10.8–11 µm). Lecanoropsis calabrica produces isousnic acid as a major metabolite, whereas L. subravida produces usnic acid, often accompanied by isousnic and/or pseudoplacodiolic acids in lower concentrations.
