Abstract
This study revises the genus() in the Mediterranean Basin, integrating single-locus and multi-locus phylogenetic analyses (ITS, LSU,, and), morphological characterisation, ecology, and arsenic accumulation in basidiomes. Morphological descriptions (including a new form,f.), comprehensive sampling, type studies, biogeography, macro- and microphotographs, an identification key, and a historical overview of the nomenclatural issues surrounding,, andare given. An epitype collection is designated for. A new method to measure spore suprahilar depression has been proposed, which allowed more clear morphological separation betweenand. This method may prove useful for species delimitation in other fungal groups that have asymmetric basidiospores. Additionally, we generated a new ITS sequence of theholotype and inferred its conspecificity with the later described. Furthermore, notes on the taxonomy ofare presented, and its placement in the genusis suggested.is confirmed as a strongly supported generic clade encompassing 21 monophyletic species-level clades, 14 of which represent known species, and seven are undescribed taxa. The synonymy ofwithis also verified. This publication provides the tools to delimitspecies that have important conservation value, which can be used by conservationists, ecologists, and citizen scientists. It also highlights species-specific arsenic hyperaccumulation in, contributing to a better understanding of fungal metal uptake. Our study indicates that within, onlydemonstrates this characteristic and is the only known member ofthat possesses a high arsenic accumulation ability.
