Full name: Agaricus crustuliniformis f. inodora Britzelm. [as "Agaricus (Hebeloma) crustuliniformis f. inodora"] (1896)
Published: Bot. Centralbl. 68: 111 (1896)
Taxonomic status: This is a Cortinarius.
Types: Not designated. Described from Germany, Lechauen, on the flood plains of the river Lech near Meitingen.

Original diagnosis: F. 444; Sp. 12 : 6; wie der Stammform, doch das Fl. geruchslos; Herbst.
