Abstract

<p>The class Dacrymycetes, a monophyletic group containing approximately 110 species of wood-decomposers in Agaricomycotina （Basidiomycota）, is appropriate for studying the evolution of wood-decaying basidiomycetes. In this paper, previous studies of Dacrymycetes are reviewed, focusing on their diversity and ecology as wood decomposers. The classification system of Dacrymycetes was revised in light of results from molecular phylogenetic analyses. As the results, a new order, Unilarcymales, was established, and some families and genera were suggested to be non-monophyletic groups. The host recurrence of dacrymycetous species was demonstrated, and factors causing recurrence were discussed from the perspective of degradation efficiency. A decay test showed that dikaryotic mycelia decompose wood blocks more efficiently than monokaryotic mycelia, suggesting that dikaryons are superior to monokaryons. A complementary method used to investigate the diversity of Dacrymycetes detected novel early-diverging lineages lacking visible fruiting bodies. Macro-fungal lineages that never produce conspicuous sporocarps might be the missing link in the Agaricomycotina phylogeny, which could increase our understanding of the diversity and evolution of mushroom-forming fungi. The diversity surveys and ecological descriptions of Dacrymycetes will provide insight into the evolution of wood-decaying basidiomycetes.</p> <p>(Japanese Journal of Mycology 57: 13−22, 2016)</p>
