The morphologically heterogeneous section Lilacinae Heim, designated by Moser (1967 and 1978) as group Obscuri, is here divided into two new subsections based on the presence or absence of caulocystidia at the apex of the stipe. The subsection Caulocystidiatae subsect. nov. includes species: Inocybe squarrosa, I. obscuroides, I. pusio, and I. cincinnatula. The subsection Caulo-acystidiatae subsect. nov. includes species: I. ochraceo-violascens (= ? I. personata), I. griseo-lilacina, I. cincinnata, and I. obscura.
