Description: Thallus crustose, white-grey to grey, thin, continuous, covered in pale to dark grey (occasionally orange at tips), cylindrical to coralloid, rarely granular isidia. Apothecia rather frequent, adnate to sessile, round to irregular, orange to rust-orange-red, with a concave to strongly convex disc and a concolorous, slightly raised proper margin. Epithecium orange, granular, K+red; hymenium and hypothecium colourless, the latter often with oil droplets; paraphyses simple or branched in upper part, 1-3 μm thick, the upper cells sometimes widened. Asci 8-spored, clavate, Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, ellipsoid (8-)10-13(-14) x (4.5-)5.5-7.5(-8) μm, the septum 3-4.5(-5) μm thick. Pycnidia often abundant, immersed, slightly raised, with an orange-red ostiole. Conidia bacilliform to narrowly ellipsoid, 3-5 x 0.8-1.5 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ red. Chemistry: anthraquinones in apothecia.
Note: a species found on bark, especially on basal parts of trunks, more rarely on lignum. Populations from southern Italy found in the Mediterranean zone (e.g. on Olea and Juniperus) could prove to belong to B. coralliza. According to Vondrák (in litt.) this species has a broadly Mediterranean distribution and is absent from America, with the easternmost limit in the Caucasus and an isolated population in the Urals, while there are some other (mostly undescribed) species which are acidophilous, growing typically on conifers and lignum, some of which also occur in Italy. The species is included in the Italian red list of epiphytic lichens as “Near-threatened” (Nascimbene & al. 2013c).
Growth form: Crustose
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by isidia, or isidia-like structures (e.g. schizidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
