Abstract
We analyzed the DNA sequences of four gene regions, 28S, 18S rDNA, ITS region and rpb2, to obtain a high-resolution phylogenetic tree of Dacrymycetes. In addition, we studied comparatively micro- and macromorphological characteristics of representative species. The traditional generic classification based on morphological characteristics is not reflected by molecular phylogenies. Ancestral state reconstructions indicated that the morphology of basidia and clamp-connections are evolutionarily stable. In contrast, basidiocarps and basidiospore septation patterns appear variable. Dacrymyces unisporus shares the typical dolipores with non-perforate parenthesomes with the other dacrymycetous taxa, but is a unique species in having predominantly non-bifurcate basidia and subglobose to ovoid basidiospores with transverse and longitudinal septations. In molecular phylogenies this species is a member of Dacrymycetes, but always occupies a basal position clearly separated from all other species studied. Based on our results we propose a new genus, Unilacryma, for D. unisporus. For proper accommodation of this taxon, we introduce the family Unilacrymaceae and the order Unilacrymales.
