Candelariella boleana Etayo, Palice & T. Sprib.

Nova Hedwigia, 89, 3-4: 546, 2009.

Synonyms:

Distribution: C - Tosc (Ravera & al. 2022b).

Description: Thallus crustose, episubstratic, of scattered, small, yellow to greenish yellow, convex, 0.05-0.15 mm wide granules sometimes confluent into 20-30 μm wide granules resembling blastidia, rarely forming a rimose-areolate crust, without a distinct prothallus. Apothecia lecanorine, yellow, 0.2-0.4 mm across, scattered to aggregated, with a flat to finally convex, bright yellow-pruinose disc and a persistent to excluded margin. Exciple with clusters of algae (5-10 μm diam.) in lower part; epithecium yellow-brown, granular; hymenium colourless, 60-70 μm high, I+ blue; paraphyses simple or sparingly branched, 2-2.5 μm thick, the apical cells not or only slightly swollen. Asci 16-32 spored, clavate, with an apical dome which is I+ blue only in the internal, lower part, interrupted in the centre by an I+ paler blue strip, Candelaria-type. Ascospores 1-celled, hyaline, globose, 4-5.5 μm in diam. Photobiont chlorococcoid, the cells 9–20 μm wide. Spot tests: thallus K-, C-, KC-, P-. Chemistry: pulvinic acid derivatives.

Note: a certainly rare epiphytic species, which is however widespread in Southern and Central Europe.
