“…Although some genera based on these criteria are not monophyletic ( Shirouzu et al 2013a ), we retained those generic concepts because no phylogenetic-based classification system has yet been established for Dacrymycetes . In similar situations, new species have been described according to the traditional system based on morphological criteria ( Shirouzu et al 2009 , 2013b , Wu et al 2011 , Delivorias et al 2012 ).…”

Dacrymycetes, sister to Agaricomycetes, is a noteworthy lineage for studying the evolution of wood-decaying basidiomycetes; however, its species diversity and phylogeny are largely unknown. Species of Dacrymycetes previously used in molecular phylogenetic analyses are mainly derived from the Northern Hemisphere, thus insufficient knowledge exists concerning the Southern Hemisphere lineages. In this study, we investigated the species diversity of Dacrymycetes in New Zealand. We found 11 previously described species, and eight new species which were described here: Calocera pedicellata, Dacrymyces longistipitatus, D. pachysporus, D. stenosporus, D. parastenosporus, D. cylindricus, D. citrinus, and D. cyrtosporus. These eight newly described species and seven of the known ones, namely, Calocera fusca, C. cf. guepinioides, C. lutea, Dacrymyces flabelliformis, D. intermedius, D. subantarcticensis, and Heterotextus miltinus, have rarely or never been recorded from the Northern Hemisphere. In a molecular-based phylogeny, these New Zealand strains were scattered throughout the Dacrymycetaceae clade. Sequences obtained from specimens morphologically matching C. guepinioides were separated into three distant clades. Because no obvious morphological differences could be discerned between the specimens in each clade and no sequence exists from the type specimen, a C. guepinioides s.str. clade could not be determined. This survey of dacrymycetous species in the Southern Hemisphere has increased taxon sampling for phylogenetic analyses that can serve as a basis for the construction of a stable classification of Dacrymycetes.

The genus Dendrodacrys is a monophyletic group that belongs to Dacrymycetes (Agaricomycotina, Basidiomycota) and accommodates species distinguished by strongly branched hyphidia in combination with 3-septate basidiospores. While the original circumscription mainly treated European taxa, here we shift the focus to tropical and sub-tropical material and uncover wider variation in morphology within Dendrodacrys. Still united by hyphidia shape and basidiospore septation, the genus is expanded with 10 taxa having pustulate, cerebriform, or stipitate basidiocarps of yellow to dark brown colours, cylindrical to ovoid basidiospores, and hyphal septa with or without clamps. Monophyly of the amended Dendrodacrys is confirmed with a phylogeny based on six markers (SSU, ITS, LSU, TEF1-α, RPB1, and RPB2). As a result, we describe two new species (De. laetum and De. rigoratum), transfer three existing species to Dendrodacrys (De. brasiliense, De. dendrocalami, and De. pezizoideum), and raise one variety to the species level (De. kennedyae ≡ Dacrymyces enatus var. macrosporus). In addition, we provide descriptions for the earlier combined De. paraphysatum and four new informal taxa. Lastly, we present illustrations, a character table, and an identification key that addresses all known dacrymycetes with branched hyphidia.

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.
