Observation 371927: Inocybe sensu lato (Site ID) (Inocybaceae)
When: 2019-06-30
Collection location: Seven Tubs Natural Area, Pennsylvania, USA [Click for map]
Who: Dave W (Dave W)
No specimen available
Notes:
Initially, I thought this was an entoloma. Presence of large hymenial cystidia and a cortina (not noticed until I zoomed in on the photo) say otherwise. The cortina strongly suggests Inocybe. However, I can’t help but wonder if the stringy material seen on the stipe and clinging to the cap margin is truly a cortina, or maybe just debris picked up from the surroundings. I say this because the cystidia (especially the last photo) look like Melanoleuca cognata cystidia.
Too immature for spores.

The more I think about this one, the less I think I know what it is. I guess the webby deposits are telltale. Big hymenial cystidia are of course common for Inocybe. But these lack ornamentation and appear to be thin-walled.
