Two new species of Phaeohelotium (Leotiomycetes: Helotiaceae) from Chile and their putative ectomycorrhizal status.

ABSTRACT: Species of the genus Phaeohelotium (Leotiomycetes: Helotiaceae) are cup fungi that grow on decaying wood, leaves, litter, and directly on soil. Northern Hemisphere species are primarily found on litter and wood, whereas in the Southern Hemisphere the genus includes a mix of saprotrophs as well as taxa that grow on soil in association with ectomycorrhizal trees. The diversity of this genus has not been fully explored in southern South America. Here we describe two species from Chile, Phaeohelotium maiusaurantium sp. nov. and Ph. pallidum sp. nov., found on soil in Patagonian Nothofagaceae-dominated forests. We present macro- and micromorphological descriptions, illustrations, and molecular phylogenetic analyses. The two new species are placed in
