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.
