Abstract
The monograph includes the results of research of the taxonomy, chemistry, ecology and distribution of <em>Stereocaulon alpinum</em>, <em>S. botryosum</em>, <em>S. condensatum</em>, <em>S. dactylophyllum</em>, <em>S. evolutum</em>, <em>S. incrustatum</em>, <em>S. nanodes</em>, <em>S. paschale</em>, <em>S. pileatum</em>, <em>S. saxatile</em>, <em>S. subcoralloides</em>, <em>S. spathuliferum</em>, <em>S. taeniarum</em>, <em>S. tomentosum</em> and <em>S. vesuvianum</em> in Poland. 1823 specimens from Polish and some European herbaria were examinated. The occurrance of <em>S. spathuliferum</em> has not been confirmed during this study, therefore its status in Poland remains unknown. During the study three lectotypes were designated. The lichenicolous fungi, <em>Cercidospora stereocaulorum</em> and <em>Roselliniella stereocaulorum</em> on <em>Stereocaulon</em> were also noted. A key to known <em>Stereocaulon</em> taxa in Poland, including <em>S. spathuliferum</em> is provided.
Highlights
Oset / The lichen genus Stereocaulon (Schreb.) Hoffm. in PolandThe name Stereocaulon (Schreb.) Hoffm. is known since 1791, when Schreber [1] used it to distinguish section within the genus Lichen L
In the present, accepted sense Stereocaulon was proposed by Hoffmann [2], who included to this genus S. condensatum Hoffm. and S. paschale (L.) Hoffm., and some species belonging nowadays to other genera: Leprocaulon Nyl., Sphaerophorus Pers., Pertusaria DC., Lichina C
In S. nanodes and S. pileatum cephalodia appear on primary thallus and pseudopodetia, while in other species they can be observed on the pseudopodetia only
Summary
The name Stereocaulon (Schreb.) Hoffm. is known since 1791, when Schreber [1] used it to distinguish section within the genus Lichen L. The first work devoted to the genus taxonomy in the twentieth century was published by Riddle [14], who reported nine species from North America and presented the key for their determination. This author, focused for the first time on phyllocladia as an important diagnostic character. An important systematic-taxonomic work is the publication by Motyka [20], which includes the characteristics of the genus, the key for European species and figures of selected taxa. It would increase the knowledge concerning Stereocaulon within the entire range of its distribution
