About this book

A taxonomic treatment of the genus Verrucaria s.l. in Poland is provided, based on a study of ca 1700 specimens from Polish and foreign herbaria. A total of 62 species belonging to seven genera currently separated within Verrucaria s.l. are presented including two new combinations, Verruculopsis minutum (Hepp) Krzewicka and Parabagliettoa disjuncta (Arnold) Krzewicka.

The following genera and species are recognized in the study area: Bagliettoa - B. baldensis (A. Massal.) Vězda, B. calciseda (DC.) Gueidan & Cl. Roux, B. marmorea (Scop.) Gueidan & Cl. Roux, B. parmigerella (Zahlbr.) Vězda & Poelt; Hydropunctaria - H. maura (Wahlenb.) Keller, Gueidan & Thüs, H. rheitrophila (Zschacke) Keller, Gueidan & Thüs, H. scabra (Vězda) Keller, Gueidan & Thüs; Parabagliettoa - P. cyanea (A. Massal.) Gueidan & Cl. Roux, P. disjuncta, P. dufourii (DC.) Gueidan & Cl. Roux; Placopyrenium - P. canellum (Nyl.) Gueidan & Cl. Roux, P. fuscellum (Turner) Gueidan & Cl. Roux, P. trachyticum (Hazsl.) Breuss; Verrucaria - V. acrotella auct., V. amylacea Hepp, V. andesiatica Servít, V. aquatilis Mudd, V. bryoctona (Th.Fr.) Orange, V. caerulea DC., V. cataleptoides (Nyl.) Nyl., V. cernaensis Zschacke, V. cincta Hepp, V. denudata Zschacke, V. dolosa Hepp, V. elaeina Borrer, V. elaeomelaena (A. Massal.) Arnold, V. funckii (Spreng.)

Nyl., V. ochrostoma Borrer, V. pachyderma (Arnold) Arnold, V. pinguicula A. Massal., V. policensis Servít, V. polonica J. Nowak, V. polysticta Borrer, V. praetermissa (Trevisan) Anzi, V. procopii Servít, V. sphaerospora Anzi, V. sublobulata Servít, V.  submauroides auct., V. submersella Servít, V. tectorum (A. Massal.) Körb., V. tristis (A. Massal.) Kremp., V. umbrinula Nyl., V. viridicans Servít, V. viridula (Schrad.) Ach., V. xyloxena Norman; Verrucula - V. elegantaria (Zehetl.) Nav.-Ros. & Cl. Roux, V. helvetica (B. de Lesd.) Nav.-Ros. & Cl. Roux, V. polycarparia Nav.-Ros. & Cl. Roux, V. protearia (Zehetl.) Nav.-Ros. & Cl. Roux; and Verruculopsis - V. lecideoides (A. Massal.) Gueidan & Cl. Roux, V. minutum.

Three species, Parabagliettoa disjuncta, Verrucula elegantaria and V. polycarparia are reported for the first time from Poland. Twenty five taxa are excluded from the survey because they were mistakenly reported or not confirmed for the study area. The morphology, anatomy, ecology and known distribution of all treated taxa are discussed. Keys for the identification of genera and particular groups of the species are provided.

Additional nomenclatural and taxonomic clarification include the typification of Thrombium lecideoides A. Massal., Verrucaria aquatilis var. aerimontana Servít and Verrucaria timkoii Servít, and the synonymy of Lithoicea nigrescens var. acrotella A. Massal. with Verrucaria nigrescens, Verrucaria amylacea f. compacta Arnold with Verrucaria amylacea, Verrucaria aquatilis var. aerimontana with Verrucaria aquatilis, Verrucaria atroviridis Servít with Verrucaria aquatilis, Verrucaria denudata f. dissulta Servít with Verrucaria funckii, Verrucaria elaeina var. determinata Körb. with Verrucaria praetermissa, Verrucaria elaeina var. effusa Körb. with Verrucaria submersella, Verrucaria hoffmanni Hepp with Bagliettoa marmorea, Verrucaria maura var. opaca Körb. with Hydropunctaria scabra, Verrucaria nigrofusca Servít with Verrucaria nigroumbrina, Verrucaria sublobulata var. robustior Servít with Verrucaria sublobulata, Verrucaria timkoii with Bagliettoa calciseda.

The name Verrucaria funckiana is rejected because it proved illegitimate as it was nomenclaturally superfluous when published.
