“…In their study on species of the ''Lecanora varia group'', Pérez-Ortega et al (2010) resolved two of the three species treated in this study as part of a monophyletic group that they informally called ''filamentosa group''. In order to formalize this distinction, we describe here the new genus Palicella.…”

Non-saxicolous lecideoid lichens form a diverse and polyphyletic group of species with a worldwide distribution. The phylogenetic relationships of the taxa and major clades are still largely unresolved. Here we introduce a new genus Palicella Rodr. Flakus & Printzen for Lecidea glaucopa Hook. f. & Tayl. and two closely related species. Our molecular phylogenetic results, based on maximum likelihood and Bayesian phylogenetic trees, and a combined dataset of five gene loci (ITS, nrLSU, mrSSU, RPB1 and RPB2), indicate that Palicella forms a monophyletic clade sister to Lecanora symmicta and Pyrrhospora quernea. The new genus is characterized by biatorine apothecia, which are often darkened (by the pigment Cinereorufa-green), an exciple of radiating, narrow hyphae with strongly elongate lumina, a hymenium with branched and sparsely anastomosed paraphyses, an ascus with a broad axial body surrounded by a distinct darker staining layer, and narrowly ellipsoid ascospores. Atranorin is present in all, usnic acid in two and pannarin in one species of the genus.

“…The final alignment contained 8 OTUs and 467 unambiguously aligned nucleotide positions. The Bayesian phylogenetic tree is presented in Figure 1 According to Pérez-Ortega et al (2010) the clade containing Lecanora symmicta (Acharius) Acharius (1814: 340) was closesly related and sister to Palicella clade (formely named "Lecanora filamentosa group"). Despite similar morphology of Lecanora symmicta group and Palicella members, both clades can be clearly segregated by ascus types, and absence or presence of atranorin respectively.…”

Palicella lueckingii (Lecanorales, Ascomycota), a new lichen species inhabiting Araucaria from the extratropical South America

Palicella lueckingii is a newly described corticolous lecideoid lichen from the Malalcahuelo National Reserve growing on the bark of Araucaria araucana in Chile. Detailed morphological studies and inference from molecular phylogenetic analyses, based on maximum likelihood and Bayesian analyses of single gene locus (ITS), clearly indicate that the new species is a member of the recently introduced genus Palicella. Palicella lueckingii is most closely related to P. glaucopa, but clearly differs in having smaller ascospores, comparatively thicker thallus, epruinose apothecia, lack of oil droplets inside of exciple and presence of thiophanic acid as a major metabolite.

“…The case of the presence of atranorin and usnic acid usually excluding each other was used to propose the separation of usnic acid containing species of Lecanora under the resurrected generic name Straminella (Pérez-Ortega et al 2010). Likewise, brown to almost black surfaces are due to melanins.…”

This article traces the changing systems in the classification of the parmelioid lichens from the early 19th century to the present day. Molecular phylogenetic approaches have enabled the relative importance of traditionally used characters to be objectively re-assessed, and led to the realization of the significance of others that had previously been passed over or dismissed; for example, differences in ascospore and conidium types or the cell-wall constituents. Information on the different characters employed is presented and assessed. It is concluded that characters related to thallus form or chemical products prove to be less informative at the generic level than has sometimes been assumed. Features requiring further study are identified, and in the light of experience in this group, lichenologists should be cautious in translating their results into formal taxonomies.The Lichenologist 43(6): 511-535 (2011)
