Inocybe agardhii

 A common fibrecap in coastal parts of West Glamorgan, e.g. Morfa Tip, Baglan Energy Park, Crymlyn Burrows, which is frequently found in dune slacks and usually associated with willows, particulary Creeping Willow (Salix repens). It is similar to Inocybe (Mallocybe) dulcamara, but unlike that species it has a distinct ring on its stem.

Known also as Mallocybe agardhii (N. Lund) Matheny & Esteve-Rav.
