Notes on Some Corticolous and Lignicolous Buellia Species From the Iberian Peninsula

Abstract

The morphology, anatomy, chemistry and ecology of some corticolous and lignicolous species of Buellia from the Iberian Peninsula that contain secondary lichen compounds are discussed, including B. chloroleuca, B. disciformis, B. erubescens, B. hyperbolica and B. leptoclinoides. These species are compared with other corticolous Buellia species that occur outside the study area, including B. arnoldii, B. insignis, B. regularis and B. sanguinolenta. The misunderstood B. zahlbruckneri J. Steiner and B. jorgei, are synonyms of B. erubescens, and the invalid taxon B. zahlbruckneri sensu Schauer non Steiner and B. poeltii, are synonyms of B. chloroleuca. New chemical data on several taxa are reported. A key to the pecies and illustrations of their ascospores are provided.

Species of lichenized Ascomycota new to Polish Western Carpathians and rare in whole Carpathians

“…Diagnostic features of the Polish specimen ( Fig. 5A-C) correspond well with the description of T. chloroleucus by Giralt et al (2000), including thallus UV+ orange, K+ and C+ yellowish, KC+ orange reactions (due to the presence of xanthone), brown thick-walled ascospores with perispore, bacilliform, straight, 4.5-5.5(-6) × 1 μm conidia and its ecological requirements. Fałtynowicz (2003) included this species within the list of lichens in Poland using the former Körber's record and additional report by Kiszka and Kościelniak (1998).…”

“…This species, under the name Buellia chloroleuca, was described by Körber (1865) based on the material collected in the currently Polish part of Sudetes. Only recently Giralt et al (2000) clearly re-defined B. chloroleuca showing characters of this species referring to Tetramelas Norman. The genus name was resurrected by Marbach (2000) for the group of Buellia s.l., which is generally characterized by the presence of xanthones (at least 6-O-methylarthothelin; see Elix, 2019), and two-layered spore wall with cracked, dark coloured perispore (Nordin, 2004).…”

Based on the re-examined type materials, Giralt et al (2000) synonymized also Buellia poeltii with B. chloroleuca. Finally, Nordin (2004) transferred this taxon to the genus Tetramelas including T. poeltii, the name earlier combined by Kalb (2004).…”

“…Considering this, T. chloroleucus is reported here from Polish Carpathians for the first time, and rediscovered in Poland after 150 years. This boreal-montane, epiphytic or wood inhabiting species is known to be widely distributed in high mountains of Europe, especially in Pyrenees, Alps (Giralt et al, 2000;Nimis et al, 2018) and Scandinavian mountains (Nordin, 2000). It has only recently been found in Carpathians, i.e.…”
