Recent collections of unknown Trichophaea-like discomycetes made in Europe enabled the authors to explore the taxonomy of Trichophaea and allies, based on morphological, ecological and molecular data. Our 3-gene phylogeny confirms the paraphyly of the genus Trichophaea and designs a new systematics for this group of cup-fungi. Three new genera are published to accommodate several species previously assigned to Trichophaea or morphologically close genera: Perilachnea gen. nov. with Lachnea hemisphaerioides as type-species, Aurantiolachnea gen. nov. with Lachnea solsequia as type-species, and Parawilcoxina gen. nov. with P. inexpectata sp. nov. as type-species. Some species of the genus Paratrichophaea belong to the cleistothecial genus Lasiobolidium, and furthermore two new species, L. trachysporum and L. coprophilum, are described. Paratrichophaea macrocystis is also combined in Lasiobolidium. Finally, three new species of Chaetothiersia, C. laricina, C. cupressicola and C. eguttulata are described. A new species of Perilachnea, P. ochraceoflava, is outlined from Italy, and a new species of Trichophaeopsis, T. asturiensis, is described from Spain. A total of 15 species are described and illustrated herein. Keys are provided.
Under the term “Trichophaea-like” discomycetes we designate an informal group of hairy cup-fungi belonging to the Pyronemataceae Corda, having a light-coloured hymenium, i.e. white, pale grey to pale brown, and […]
