Abstract

A new genus named Dendrodacrys is proposed for a monophyletic group in Dacrymycetaceae, containing species with pulvinate to depressed basidiocarps, distinctly branched hymenial hyphidia, and up to 3-septate mature basidiospores. Four taxa in this group, occurring in Europe, are proposed as new species, viz. De. ciprense, De. concrescens, De. ellipsosporum, and De. oblongisporum, based both on morphological and DNA data (nrDNA, RPB1 , RPB2, TEF-1α, 12S). These new species are all described in detail, illustrated, and compared with other published taxa that with which they can be confounded. The new combination De. paraphysatum is proposed after revising the type material of Dacrymyces paraphysatus, but other combinations or potentially new non-European species descriptions are postponed pending further studies of additional specimens.
