Abstract: Oset, M. & Otte, V.: Flavoparmelia soredians new to Poland – Herzogia 34: 524 –527. A total of nearly 700 Flavoparmelia specimens from Poland were checked, complemented by recent field observations. Among them, nine specimens of F. soredians were revealed. Most of them were found in the last few years, but the oldest collections date back...

Pertusaria atropallida and P. uralensis are found to represent synonyms of the lichenized fungus P. coccodes. Lectotypes are selected for P. atropallida and P. uralensis.

Pertusaria inopinata Erichsen (= Lepra excludens (Nyl.) Hafellner), P. jurana Erichsen (= Lepra albescens (Huds.) Hafellner) and P. jurana var. confluens Erichsen (= Ochrolechia turneri (Sm.) Hasselrot) are synonymized based on results from comparison of morphology and secondary compound chemistry of type material. Lectotypes are selected for Pertu...

Pyrcha, M. & Oset, M. 2019. Saxicolous species of the genus Pertusaria s.l. in Poland. – Herzogia 32: 385 –397. Notes on the morphology, secondary chemistry, habitat requirements and distribution of saxicolous species belonging to the genus Pertusaria s.l. in Poland are provided. The following species are treated: Lepra aspergilla, L. corallina, L....

To test the taxonomic significance of secondary chemistry (particularly lobaric acid and fatty acids) and pruina in Parmelia ernstiae, P. saxatilis, P. serrana, P. submontana and P. sulcata in Europe, 3684 specimens were analysed morphologically and chemically, and 82 ITS rDNA sequences were prepared. A comparison of the resulting phylogram with th...

Lecanora stainislai is characterized by a very thin sorediate thallus, forming a more or less continuous layer of soredia and by the production of usnic acid and zeorin. It usually grows on smooth bark of trees in forests and is known from the Czech Republic, Norway, Poland, Russia, Ukraine and western North America (Canada, USA). It is chemically...

Knowledge of the relationships and thus the classification of fungi, has developed rapidly with increasingly widespread use of molecular techniques, over the past 10–15 years, and continues to accelerate. Several genera have been found to be polyphyletic, and their generic concepts have subsequently been emended. New names have thus been introduced...

The paper lists 337 species from Magurski National Park (MNP): 314 lichens, 18 lichenicolous fungi, four saprotrophic fungi and one lichenicolous myxomycete; 112 of them are new for MNP, 75 are reported for the first time for the Beskid Niski Mts, and two are new for Poland. Selected species are accompanied by taxonomic notes and remarks on their d...

The nomenclature, bibliographic citations and typifications of the names Stereocaulon botryosum and S. condensatum are discussed. A neotype is designated for S. condensatum and the lectotypification of S. botryosum is clarified. In addition, the morphological and chemical characteristics of both species and information on exsiccates examined are pr...
