Gonatophragmiopsis verrucosa gen. & sp. nov. and Pithomyces dimorphosporus sp. nov. from Brazil
A new genus and species, Gonatophragmiopsis verrucosa , from decaying leaves of an unidentified Annonaceae, and a new species, Pithomyces dimorphosporus, from decaying leaves of an unidentified dicotyledonous plant, both collected in Brazil, are described and illustrated. Gonatophragmiopsis verrucosa is distinguished by distinct, erect, euseptate, unilateral branched, yellowish olivaceous-brown conidiophores; discrete, polyblastic conidiogenous cells; and cylindrical or long oblong, straight or curved, 0–7-septate, verrucose or verruculose, yellowish olivaceous-brown conidia. Pithomyces dimorphosporus is characterized by dimorphic conidia: type 1) ellipsoidal, oblong pyriform, obovoid to subglobose, 0–3-septate, echinulate or verrucose, non-rostrate; and type 2) obpyriform, verrucose, 1-septate, with a long rostrate apical cell.
