= * Immotthia atrograna (Cooke & Ellis) Barr
The cited specimens contain the stromata of a Hypoxylon, possibly H. perforatum (Schwein.: Fr.) Fr., which is heavily parasitized by Immotthia atrograna (Cooke & Ellis) Barr and its sphaeropsidaceous state. Schweinitz's protologue (1822) clearly indicates that it is this parasitizing fungus that he intended to describe. Fries (1828) listed S. insidens Schwein.: Fr. as a synonym of Sphaeria atramentosum Fr.: Fr. This is unacceptable because the former is not the same as any of the three fungi associated with the latter name [see the entry of H. atramentosum (Fr.: Fr.) Sacc in this list].
