Revisions to the Gliophorus irrigatus complex (Agaricales, Hygrophoraceae, Gliophorus, section Unguinosae) including a new waxcap, G. alboviscidus, from the UK but detected globally via soil eDNA, two new species from eastern North America, G. fumosus and G. parafumosus, plus a new species, G. calunus, and a new combination of Hygrophorus subaromaticus in Gliophorus from western North America.

The paper describes four new species in the Gliophorus irrigatus complex, highlights the role of citizen scientists in documenting fungal distributions, and discusses discrepancies between eDNA and basidiome distributions.
