Under Alder, spores smooth, cheilocystidia bottle shaped, so section Naucoria. Spores 8.4-10.1 x 4.9 – 5.7 um.
Some of the cystidia look to have small crystals, so I did consider a smooth Inocybe, but Macroscopically it looks like a Naucoria more.
No significant smell, taste mild. Not hygrophanous.
Naucoria spores are typically a different shape too.
Keying to N. spagneti in Funga Nordica which is apparently rare.
Could it be something else?
