Re : Info bibliografiche
Hello, 

complete citation is probably: Donk, M.A. (1964): Pyrenomycetes. In: Nomina conservanda proposita. Regnum Vegetabile 34: 16-31.
I don't have it, but in the Nemania monograph by Ju & Rogers (2002) they wrote: "Donk (1964) argued convincingly that Nemania should be lectotypified on Sphaeria serpens Pers., i.e., making Gray's species number 4, Nemania serpens (Pers. : Fr.) S.F. Gray, the type species of the genus. Previously, most authorities had accepted this species as Hypoxylon serpens (Pers. : Fr.) J. Kickx fil." 

Best regards.
Viktorie
