Poelt J. & Petutschnig W. (1992): Xanthoria candelaria und ähnliche Arten in Europa, Herzogia, 9: 103-114

Key Words: Lichens, diaspores, blastidia, Xanthoria, Teloschistaceae. Abstract: The five European species of the Xanthoria candelaria complex are keyed and discussed. For detailed descriptions we refer to a larger paper on the genus Xanthoria in the Himalayan region (POELT & PETUTSCHNIG 1992). Xanthoria candelaria S.str. seems to be distributed nearly over the whole European continent; X. borealis is restricted to the Scandinavian mountains and the Arctic; X. fallax, X. fulva, and X. ulophyllodes … EN Read more...

Poelt J. & Hafellner J. (1975): Schlauchpforten bei der Flechtengattung Thelocarpon, Phyton, 17: 67-77

The genus Thelocarpon (incl. Ahlesia) includes with all transitions species with open to closed ascocarps. The probable change of the function of the ascocarps seems to be connected with a series of reductions of the apical apparatus from well developed over poorly developed and present for a short time to completely deficient. According to the used criterion (form of the ascocarp, paraphyses, form of the ascus, apical apparatus) a subdividing of the genus would bring different results and … EN Read more...

Remarkable collections of lichens from Austria, especially from Styria, are recorded. 25 species and 1 subspecies (probably better species) are new to Austria; in addition to these, 12 species are new to Styria. The taxa are annotated, and the taxonomy, ecology and geographical distribution of some groups are discussed in more detail: Cladonia uncialis with special regard to subsp. biuncialis, and some groups oí Aspicilia, especially A. calcarea coll. , and the species of arctic-alpine distribution currently … EN Read more...
