Caloplaca monacensis (Leder.) Lettau

Hedwigia, 52: 240, 1912. Basionym: Pyrenodesmia monacensis Leder. - Ber. bayer. bot. Ges., 4: 26, 1896.
Synonyms: Caloplaca cerina var. cyanolepra (DC.) J. Kickx f.; Caloplaca cerina var. erhartii (Schaer.) Trevis.; Placodium cerinum f. cyanoleprum (DC.) Anzi
Distribution: N - Frl. Ven (Šoun & al. 2011), TAA (Šoun & al. 2011), Emil (Fariselli & al. 2020). C - Umb (Ravera 1999).
Description: Thallus crustose, episubstratic, almost entirely granular, sometimes indistinctly areolate especially around apothecia, thick, grey, usually with a bluish tinge, forming regular to irregular patches to 3 cm in diam. Granules isidioid, coarse, 70-160 µm in diam., sometimes with inconspicuous hairs formed by projecting hyphae. Apothecia lecanorine, 0.7-2 mm across, sessile, with a slightly concave to slightly convex, yellow-orange to orange disc (grey-black in rare forms without anthraquinones), and a persistent, thick, grey, often granulose thalline margin. Thalline exciple paraplectenchymatous, to 170 µm thick in lower part; proper exciple very thin, prosoplectenchymatous; epithecium orange, with inspersed granules, K+ red; hymenium colourless; paraphyses simple to branched in upper part, c. 1-2 µm thick at base, with rather swollen, 4-6 µm wide upper cells. Asci 8-spored, cylindrical-clavate, Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, ellipsoid, 11-16(-18) x 5-8 µm, the septum 3-6(-8) µm thick. Pycnidia immersed, with an elevated, darker ostiole. Conidia hyaline, bacilliform, c. 3 x 0.5 μm. Photobiont chlorococcoid. Spot tests: thallus K- or K+ violet, C- or C+ violet, KC-, P-; disc of apothecia K+ red (rarely K- in rare forms without anthraquinones); upper part of pycnidial wall K+ violet. Chemistry: thallus and pycnidia with the Sedifolia-grey pigment; disc of apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor), very rarely without anthraquinones.
Note: on isolated trees with subneutral, base-rich bark; I have observed this species several times in the plains of northeastern Italy, where it is locally common on poplars. The record of an epiphytic C. isidiigera by Ravera (1999) most probably refers to this species.
Growth form: Crustose
Substrata: bark
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
