If I should find more time and if I shall succeed in entitling and assembling my pics I will post my finds from Sweden and Finland from 2010 here.

Thanks Gerhard!

Darn, makes me wonder if we need to take a closer look at our versipelles too..

whereas cap of L.rufescens/versipelle should be regularly smooth, microscopically L.atrostipitatum has no cylindrocysts in the cap cuticle, cuticle hyphae in Melzers no tendency for pigment balls formation in L.atrostipitatum, stipe more scaly than in L.versipelle, context in FeSO4 in L.versipelle green to olive to yellow, in L.atrostipitatum bluish gray, guajak blue in L.atrostipitatum, green in L.versipelle, NH4OH in L.versipelle gray-yellow, in L.atrostipitatum bluish, caulocystidia in L.versipelle clavate, in L.atrostipitatum in general utriform. L.atrostipitatum in Europe is rare and seemingly more mountaineous-boreal.

does atrostipitatum differ from versipelle?
