| Sumario: | <i>Tolypocladium</i>, a diverse genus of fungicolous fungi belonging to <i>Ophiocordycipitaceae</i>, includes saprotrophic soil inhabitants, plant endophytes and pathogens of insects, nematodes, rotifers, and parasites of truffle-like fungi. Here, we review the research progress achieved for <i>Tolypocladium</i> regarding its taxonomy, species diversity, geographic distribution, host affiliations and ecological diversity. Furthermore, an undescribed taxon from China was established using morphology and multi-gene phylogeny. <i>Tolypocladium inusitaticapitatum</i> is introduced as a new species parasitizing ectomycorrhizal <i>Elaphomyces</i> species. It is diagnosed by its irregularly enlarged fertile heads and lemon, yellow-to-dark-brown, smooth and nearly cylindrical stipe. Phylogenetic analyses based on SSU, LSU, ITS, <i>TEF</i>1-<i>α</i> and <i>RPB</i>2 sequence data showed <i>T. inusitaticapitatum</i> to be an independent lineage separated from <i>T. flavonigrum</i> in the clade comprising <i>T. capitatum</i>, <i>T. fractum</i> and <i>T. longisegmentatum</i>. A key for identifying the sexual <i>Tolypocladium</i> species is also provided. |
