New and interesting Laboulbeniales (Fungi, Ascomycota) from the Netherlands, II

Abstract

Twenty-three species of Laboulbeniales (Fungi, Ascomycota) are reported for the first time from the Netherlands. These are Appendiculina scaptomyzae, Autoicomyces aquatilis, Cantharomyces denigratus, Chitonomyces hydropori, Eusynaptomyces hydrobii, Hesperomyces coccinelloides, Hydrophilomyces atroseptatus, Laboulbenia expectata sp. nov., L. hyalopoda, L. murmanica, L. ophoni, L. thaxteri, Rhachomyces lavagnei, Rhadinomyces cristatus, Rhynchophoromyces anacaenae, Stigmatomyces crassicollis, S. divergatus, S. ephydrae, S. geomyzae, S. ptilomyiae, S. purpureus, Tavaresiella hebri, and Thripomyces tessinensis. Laboulbenia expectata sp. nov. is uniquely associated with Pterostichus vernalis and is also reported from Belgium, Czechia, Denmark, Germany, Poland, and Spain. Morphological characteristics and a four-locus phylogenetic reconstruction recognized it as a new species in the L. flagellata species complex. New host species for the Netherlands are reported for Chitonomyces bidessarius, Hydraeomyces halipli, and Zodiomyces vorticellarius.
