A revision of Hebeloma sect. Indusiata in the Nordic countries

A revision of Hebeloma sect. Indusiata in the Nordic countries has been undertaken. The type species of the genus, Agaricus fastibilis , is interpreted as being a non-veiled species, and therefore sect. Indusiata is the correct name for the section comprising the veiled, non-rooting species of Hebeloma. Subsect. Amygdalina subsect. nov. is proposed for species in sect. Indusiata possessing amygdaloid, dextrinoid spores. The following new taxa and combinations are proposed: Hebeloma mesophaeum var. crassipes var. non., H. mesophaeum var. lacteum nom. et stat. nov., H. polare sp. nov., H. sordescens sp. nov., H. atrobrunneum sp. nov., H. monticola sp. nov. and Agrocybe elatella comb. nov.
