Pileus: 39-55mm across.  Bright white developing yellowish tan stains. Flesh: Off-white with faint tan stain. Taste: Mild to slightly sweet.  Lamellae: Pallid when young, developing rusty tones in maturity. Veil: Thick, membranous, white veil persisting through maturity.

ITS

Analysis: I have not found the type of Cortinarius magnivelatus publicly available.  However, the relatively short sequence I have from this collection matches several magnivelatus collections as well as being close to a sequence for the type collection of Cortinarius wieberi. It also matches the description of the species. Work is needed to clarify the velate species in our region.
