Blastenia herbidella (Hue) Servít
Hedwigia, 74: 148, 1934. Basionym: Lecidea caesiorufa f. herbidella Nyl. ex Hue - Nouv. Arch. Mus., sér. 5, 3: 151, 1913.
Synonyms: Caloplaca caesiorufa auct. ital. p.p; Caloplaca herbidella (Hue) H. Magn.
Description: Thallus crustose, episubstratic, white-grey to grey, very rarely yellowish, usually <100 μm thick, continuous, covered in pale to dark grey (occasionally orange at tips), cylindrical to coralloid, rarely granular, 60-160 μm thick and up to 600 μm tall blastidia/isidia. Apothecia biatorine/zeorine, rather frequent, 0.7-1.2 mm across, 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. Proper exciple prosoplectenchymatous, C+ purple; epithecium orange, granular, K+ red, C-; hymenium colourless, not inspersed with oil droplets; paraphyses simple or sparingly branched and anastomosing, 1.5-3 μm thick in lower part, the apical cells usually wider; hypothecium colourless, often with oil droplets. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid (9.5-)10-15(-17) x (4.5-)5.5-7.5(-8) μm, the equatorial thickening (“septum”) 3-4.5(-5) μm. 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: non-chlorinated anthraquinones in apothecial disc, chlorinated anthraquinones in exciple; thallus without anthraquinones or rarely yellow with anthraquinones; Cinereorufa-green pigment usually absent or in traces, but often detectable in tips of isidia/blastidia.
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)
