Cort or Inocybe?

[Paul Hugill]

I hope someone can help me with this one. Found in a wet alder carr. Has brown gills which are adnate and brown spore print. Spores about 10.5-13.1 x 6.1-6.8, filled with granular contents and are thick walled.The four spored basidia are fat clavate 27x10 and also filled with granular material. The cap appearance is like an Inocybe but I can't find anything of this colour in the lit. Nothing in the Alnicolas either. So maybe it is one of the Corts that are mycorhizal with alder?

What shape are the spores and are they smooth or 'rough'? Many Naucoria and Cortinarius species will have spores with a rough/verrucose appearance and many species have almond-limoniform shaped spores. Inocybe spores (except the 'knobbly' ones) are smooth. Also the majority of Inocybe spp. have very distinct gill edge cystidia (with crystals on top) which will easily distinguish this Genus from Naucoria or Cortinarius.
