'''''Amandinea''''' is a genus of lichenized fungi in the family Caliciaceae.<ref name="Wijayawardene et al. 2020"/> Genetic studies indicates that the genus ''Amandinea'' and ''Buellia'' are the same,<ref>Scheidegger, C. 2009.

==Taxonomy==
The genus was originally circumscribed by Maurice Choisy in 1950, with ''Amandinea coniops'' assigned as the type species.<ref name="Choisy 1950"/> However, the name was published invalidly because it was not accompanied by a Latin description or diagnosis, a requirement of the nomenclatural rules of the time.<ref name="IF: Amandinea M.Choisy 1950"/> Christoph Scheidegger and Helmut Mayrhofer published the genus name validly in 1993.<ref name="Scheidegger 1993"/> The generic name honours French Madame Amandine Manière, an acquaintance of Choisy.<ref name="Hertel 2012"/>
==Description==
''Amandinea'' species have a crustose thallus ranging from cracked (rimose) to slightly blistered (bullate). The internal white layer (medulla) is iodine-negative (I−), meaning it does not turn blue in the standard iodine test and is therefore non-amyloid. The photosynthetic partner is a {{lichengloss|chlorococcoid}} green alga, i.e. with small, spherical cells. Sexual fruiting bodies are apothecia with either a {{lichengloss|lecanorine}} margin (rim made of thallus tissue) or a {{lichengloss|lecideine}} margin (dark, non-thalline rim). These apothecia may be partly sunk into the thallus ({{lichengloss|immersed}}) or sit on top of it ({{lichengloss|sessile}}), with either a broad or narrowed base; the {{lichengloss|discs}} are typically black or nearly so. The tissue beneath the spore layer ({{lichengloss|hypothecium}}) is pale to dark brown, sometimes with olive tones.<ref name="Cannon et al. 2020"/>
Inside the apothecia, the {{lichengloss|hamathecium}} is made of paraphyses—microscopic, partitioned threads that run between the spore sacs. These are unbranched or branch only near the tip; the tips are swollen and pigmented, and many bear a dark brown cap. The asci (spore sacs) are club-shaped and of the ''Lecanora''-type; they usually contain eight spores, though four or more than eight may occur. The ascospores are brown and 1-septate (with a single internal cross-wall), sometimes showing a thicker median wall; their surfaces are often finely wrinkled ({{lichengloss|rugose}}), a feature that generally requires electron microscopy to see reliably. Asexual reproduction is common via pycnidia (tiny flask-like structures) that produce curved, thread-like conidia up to about 30 μm long. Chemical tests rarely detect secondary metabolites in this genus (norstictic acid is uncommon but occurs in a few species), while most species show no substances detectable by thin-layer chromatography.<ref name="Cannon et al. 2020"/>
