New and rare Laboulbenialis (Ascomycetes) from the Białowieża Forest (NE Poland)

Abstract

This paper presents descriptions of some interesting species of the <i>Laboulbeniales</i> collected by the author in the Białowieża Forest and its foreland (NE Poland) in the period 1994-1998. Among them are 18 determined species new for Poland, four new for science (<i>Corethromyces bialowiezensis</i> sp.n. on Tachyporus solutus, Cryptandromyces bryaxidis</i> sp.n. on <i>Bryaxis bulbifer, Euphoriomyces unilateralis</i> sp.n. on <i>Agathidium atrum</i>, and <i>Phaulomyces ptilii</i> sp.n. on <i>Ptilium affine</i>), and two or three species new for Europe (<i>Peyritschiella geminata</i> Thaxter, <i>Zodiomyces subseriatus</i> Thaxter and perhaps <i>Laboulbenia epithricis</i> Thaxter). Four species are probably new for science but the collected material is too scanty to describe them. Additionally, details concerning morphology or systematic position of some species known already from Poland are supplemented. These data essentially complemented a recent description of Polish species of the group (Majewski 1994).
