Caloplaca grimmiae (Nyl.) H. Olivier

Mém. Soc. Sc. Nat. Cherbourg, 37: 119, 1909. Basionym: Lecanora grimmiae Nyl. - Flora, 69: 97, 1886.
Synonyms: Caloplaca congrediens auct. non (Nyl.) Zahlbr.; Caloplaca consociata J. Steiner; Pisutiella grimmiae (Nyl.) S. Y. Kondr., L. Lőkös & E. Farkas

S - Bas (Nimis & Tretiach 1999), Cal (Puntillo 2011), Si (Nimis & al. 1996b, Brackel 2008c).
Description: Thallus mostly immersed in that of the host, sometimes visible externally as small, dark grey granules, otherwise reduced to the margin of apothecia. Apothecia lecanorine, 0.3-0.7(-1.3) mm across, st first immersed, then subsessile, with a flat to convex, brown-red to orange-red disc, and a thick, dark grey, finally sometimes almost excluded thalline margin. Proper exciple paraplectenchymatous laterally, prosoplectenchymatous below the hypothecium; epithecium orange-brown, granular, K+ red; hymenium colourless, 70-85 µm tall, amyloid; paraphyses often sparingly branched in upper part, c. 1.5 μm wide at base, the apical cells slightly swollen, up to 4 μm wide; hypothecium colourless. Asci 8-spored, cylindrical or cylindrical-clavate, Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, ellipsoid to broadly ellipsoid,, 10-14 x 5-7 μm, the septum 2.5-4 μm thick. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecial disc K+ red. Chemistry: thallus without lichen substances; unidentified anthraquinones in the epithecium.
Note: a holarctic, temperate to boreal-montane lichen, whose ecology and distribution are narrower than those of its host. It occurs throughout the country, exceptionally also in the Mediterranean belt, sometimes on walls, but, contrary to the host, is absent from heavily disturbed habitats. According to Vondrák (in litt.) this species is closely related to C. congrediens and C. phaeothamnos; molecular (ITS) data show that these three species could belong to a still undescribed genus, the closest outgroup being formed by C. conversa and C. conglomerata.
