Bryoria kuemmerleana (Gyeln.) Brodo & D. Hawksw.

Opera Bot., 42: 155, 1977. Basionym: Alectoria kuemmerleana Gyeln. - Magyar Bot. Lapok, 30: 54, 1931.
Synonyms:
Distribution: N - TAA (B-5695).
Description: Thallus fruticose, filamentous, to 20 cm long, pendent, pale brown to dark brown, sometimes with blackened fragmentation areas, dull to slightly shiny, pruinose (best seen in basal portions), ainly isotomic dichotomously branching, without distinct main branches, the branches usually even or sometimes partly compressed and foveolate, 0.07-0.4(-0.5) mm thick. Soralia present or absent, mostly tuberculate but sometimes fissural, often dark grey. Pseudocyphellae conspicuous, brownish white, elongate-fusiform, sometimes twisted, 0.2-0.7(-0.9) mm long. Apothecia rare, with a brownish, distinctly pruinose disc and paler margin, to 2 mm across. Asci 8-spored, Lecanora-type. Ascospores 1-celled, hyaline, globose to broadly ellipsoid, 4-7 x 4-5 μm. Spot tests: thallus and soralia K+ red, C-, KC-, P+ yellow. Chemistry: norstictic acid, sometimes also connorstictic acid and atranorin; apothecia with psoromic acid (K-, P+ yellow).
Note: a rather poorly known species with partly pruinose thalli reacting K+ red, C-, and elongate, fusiform pseudocyphellae, found on the bark of various trees; the identification of the Italian material, collected by Grumman at Carrer Pass, should be checked. The study of Boluda et al. (2019) revealed a strong mismatch between phenotypes and genotypes in Bryoria sect. Implexae, which brought to the reduction from 11 to 4 species. All European species (B. capillaris, B. chalybeiformis, B. implexa, B. lanestris, B. kuemmerleana, and B. subcana) should be considered as synonyms of B. fuscescens. Due to their chemical and morphological differences, I still provisionally maintain these taxa as separate species, although they should be best treated as chemical races or forms of B fuscescens.
Growth form: Fruticose filamentous
Substrata: bark
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
