【 摘 要 】

The new corticioid genus and species,Tsugacorticium kenaicumfrom Alaska, is described. Primarily found on attached, dead, corticate branches of mountain hemlock in the Kenai Peninsula,T. kenaicumis characterized by small, soft, white to yellow basidiomata, thickened subhymenium, much branched dendrohyphidia, and small globose to subglobose basidiospores. Although morphologically similar toDendrothele(Agaricales) andDendrocorticium(Corticiales), phylogenetic analyses of the nuclear large subunit ribosomal RNA gene place this taxon in the Rickenellaceae clade in the Hymenochaetales.Tsugacorticium kenaicumis described, illustrated, and compared to morphologically similar and phylogenetically related taxa.
