Apologies for the awful photo. I wasn’t particularly focused on this collection and didn’t capture it well. Per: Joe and Kare, this matches the type for C.substriatus. The type location is Lake Cushman, WA and this was collected on Vancouver Island. It was noticeably viscid capped in wet conditions and was growing in young mixed conifer forest in moss. My first thought was C.subpurpureus (Smith) but collections matching this description need further research as there is some confusion with the type collection. I hope to collect more examples and better photographs this coming fall.

Per: Ammirati / Liimatainen Sequence matches Cortinarius substriatus (Kauffman, 1915)
