 membrana modice incrassata aut sat tenui, interdum autosporis 

 globosis aut subellipsoideo-globosis, diam. O.003 — O.0035 mm, in- 

 structa (in specim. Arn.).

 Jokioinen et Arokoski in Padasjoki et Hietala in Luhanka (Vain.). 



Obs. Var. subviolacea (Lang) Vain., hypothecio parte superiore 

 sordide pallido et partim rufescenti-pallido a f. coprode differens, ad
