Abstract
Vuilleminia nilsii sp. nov. is described based on collections made in Argelès-sur-Mer communal forest, France. It is characterized by a resupinate, smooth, whitish, decorticating basidiocarp, cylindrical cystidia, heavily crystallized matrix, and guttulate, allantoid spores. It can be distinguished from V. coryli by basidiospore size, substrate preferences, abundance of dendrohyphidia, and crystal in the context. Phylogenetic analyses place Vuilleminia ericae, Dendrothele dryina (= V. dryina) and Dendrothele maculata in a distinct, well-defined clade. The new genus Dendrominia is proposed for this clade. The new combinations Dendrominia dryina, D. ericae, and D. maculata are proposed. Dendrothele corticola is regarded as a synonym of D. maculata. A lectotype is selected for V. macrospora. An updated key to the genus Vuilleminia and a key to Dendrominia species are provided.
