On Protomerulius and Heterochaetella (Auriculariales, Basidiomycota)

The taxonomy of Protomerulius and Heterochaetella is revised based on DNA data and morphological evidence, and their type species, P. brasiliensis and H. dubia, are proved to be congeneric. As a consequence, H. dubia and related species, of which four are described as new, are placed in Protomerulius. Heterochaete microspora is also combined in Protomerulius, and the genus concept is redefined to encompass effused species with smooth or spiny hymenophore and monomitic hyphal structure. Psilochaete multifora, gen. and spec. nov. is a distant relative of Protomerulius spp. found in Norway. Heterochaetella cystidiophora is re-collected in Brazil and placed in the synonyms of Heterochaete sanctae-catharinae. This species does not belong to the Protomerulius-Heterochaetella lineage, and it is transferred to Metulochaete, gen. nov.Peer reviewe

Vedboende sopp: betydning, økologi og utbredelse

Dette kompendiet er skrevet for å gi en oversikt over våre viktigste råtesopper og deres betydning både i økosystemet og forvaltningen av våre skoger. Råtesoppene har bestemte livskrav, og deres forekomst eller fravær forteller derfor noe om skogens tilstand og histori

Neotropical Perenniporia: a new species, Perenniporia subovoidea sp. nov., from Costa Rica, new records of little known species, and a key to the species with a resupinate basidiome

Background and aims – This study is a part of an ongoing survey of Perenniporia (Basidiomycota, Polyporales) in the Neotropics. Methods – Material is examined and described using morphology-based methods. Key results – Perenniporia subovoidea is proposed as new. New records of little known species are presented. A key to the Perenniporia species with resupinate basidiome is also presented. Conclusion – Perenniporia subovoidea is reported from Costa Rica. New records of P. aurantiaca, P. chromatica, P. parvispora, P. roseo-isabellina, and P. xantha are presented. All these species are endemic to the Neotropical areas

Additions to the Neotropical <I>Perenniporia</I>: <I>Perenniporia albo-incarnata</I> comb. nov. and <I>Perenniporia guyanensis</I> sp. nov.

In the continuation of the revision of the Neotropical species of Perenniporia (Basidiomycota) with resupinate basidiomes, the new combination Perenniporia alboincarnata and the new species Perenniporia guyanensis are proposed; both species are described and illustrated.</p
