Lecanoropsis coppinsii (M. Brand & van den Boom) Ivanovich & Printzen, comb. nov. MycoBank nº: 847145 Basionym: Lecanora coppinsii M. Brand & van den Boom, in van den Boom & Brand, Lichenologist 40 (6): 470 (2008). Type:— SCOTLAND. V.C. 82 East Lothian, Lammermuir Hills, Monynut Forest, 36/689.671, 340 m alt., 31 October 1999, B. J. Coppins 18567 (E— holotype; hb. v.d. Boom— isotype; not studied). Description: see van den Boom & Brand (2008). Notes: A species so far only known from southern Scotland, Lecanoropsis coppinsii could be confused with L. latens and L. omissa. However, L. coppinsii produces larger apothecia (0.4–0.8 mm) than L. latens [0.2–0.35(–0.5) mm] and L. omissa [0.2–0.4(–0.5) mm]. In addition, L. omissa and L. latens produce usnic acid, whereas L. coppinsii produces isousnic acid as secondary metabolite. The pruina in L. coppinsii is grey-blue whereas L. latens produces a whitish pruina. Finally, L. latens is only known from the west coast of California in the US, and L. coppinsii has so far only been collected in the northern part of the British Isles. Lecanoropsis coppinsii produces the shortest ascospores within Lecanoropsis, reaching a maximum length of 8.5 µm (see van den Boom & Brand (2008); see Table 2 for comparison).
