Specimen available

Original Herbarium Label: Inocybe paludinella var. umbratica (Quél.) Gminder

Inocybe paludinella (Peck) Sacc. and Inocybe umbratica Quél. are two closely related species. Some authors (Stangl 1989, Ferrari 206) suggested that Inocybe palludinella and I. umbratica should be treated as one species. This was formally done by Gminder when he transferred I. umbratica into I. paludella as a variety: Inocybe paludinella var. umbratica (Quél.) Gminder.
This specimen (collected by Dennis Oliver) is closer to Inocybe paludinella s.str. when considering the color of the cap (yellow vs. brownish tinge), but the size of spores fits better to I. umbratica (which has slightly larger spores than those listed for I. paludinella).
WARNING: Without microscopic examination, collections of this species complex can be easily misidentified as Inocybe geophylla!
