Distribution: N - Ven (Lazzarin 2000b), Piem (Burgaz & al. 2020), Lig (Ravera & al. 2015). C - Tosc (Ravera & al. 2015, Gheza & al. 2020), Laz (Ravera & al. 2015). S - Cal (Puntillo 1996, Ravera & al. 2015), Si (Nimis & al. 1994, Ottonello & Romano 1997, Ottonello & al. 2011, Ravera & al. 2015).
Description: Primary thallus crustose, ephemeral and rarely seen. Podetia pal straw-yellow or ash-grey, shrubby, richly anisotomically (i.e. main branches thicker)-dichotomously branched, with closed axils, ecorticate (with a minutely arachnoid surface), 4-7(-10) cm tall, 0.5-1(-1.2) mm thick, the main branches thicker, the pointed apices unilaterally deflexed. Apothecia rather rare, brown, convex. Asci 8-spored, clavate, thickened at apex, with a K/I+ blue tholus and a K/I+ strongly blue outer gelatinous sheath, Cladonia-type. Ascospores 1-celled, hyaline, ellipsoid. Pycnidia dark, semi-immersed, on the tips of podetia, with a red jelly. Conidia cylindrical. Photobiont chlorococcoid. Spot tests: K-, C-, KC- or KC+ yellow, P+ red, UV-. Chemistry: chemotype 1): fumarprotocetraric and occasionally traces of usnic acid (thallus grey); chemotype 2) fumarprotocetraric and usnic acid (thallus yellowish); Italian records refer to the latter. Note: a rare temperate species found on mosses in shrublands, especially in undisturbed maquis vegetation, restricted to humid areas. The species occurs in two chemotypes which rarely grow together, the colour varying from dark brown to straw-yellow in f. flavicans (Flörke) Ahti & DePriest.

It was assessed as “Endangered” in Italy by Ravera & al. (2015).
