Herzogia, 9: 52, 1993. Basionym: Lecidea aggregantula Müll. Arg. - Flora, 57: 533, 1874.

Synonyms: Nesolechia aggregantula (Müll. Arg.) Rehm

Distribution: N - Frl (Tretiach & Hafellner 2000, Brackel 2016, Hafellner 2021), TAA (Hafellner 1996, 2006, 2023, Brackel 2016, Hafellner 2021), Piem (Hafellner 2021).

Description: Thallus non-lichenized, indistinct, immersed in the thalli of species of the Lecanora polytropa-group. Apothecia biatorine, 0.2-0.3 mm across, black, somehow glossy, sessile, often clustered, with a strongly convex disc, without a distinct proper margin. Proper exciple strongly reduced; epithecium bluish green-black, sometimes in part brown, N+ violet; hymenium colourless, 40-50 µm high; paraphyses coherent, strongly swollen in water, 4-5.5 µm thick at base, the apical cells 5-8 µm wide; hypothecium colourless in upper part, pale yellow-brown in lower part. Asci (4-)8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the outer wall very thin, K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled (rarely 1-septate), hyaline, fusiform to bacilliform with rounded ends, 8-12 x (2-)3-4.5 µm. Photobiont absent. Spot tests: all negative. Chemistry: without lichen substances.

Note: a lichenicolous fungus, certainly much more widespread in the Alps.
