Sydowiellaceae is a poorly studied family of the order Diaporthales, comprising acollection of morphologically diversified taxa. Eleven genera have been previously listedunder this family. In this study, we provide a DNA sequence-based phylogeny for genera ofSydowiellaceae based on analyses of a combined LSU, ITS, RPB2 and TEF sequence datasetto establish the boundaries within the family. We introduce, describe, and illustrate three newgenera, Italiomyces, Ranulospora, and Tenuiappendicula, based on newly collectedspecimens. Another three new genera, Alborbis, Breviappendix, and Paragnomonia areintroduced to accommodate Cryptodiaporthe galericulata, Gnomonia rosae, G. rostellata, G.rubi, and G. fragariae. Alborbis galericulata comb. nov., Breviappendix rubi comb. nov., B.rosae comb. nov., B. rostellata comb. nov. and Paragnomonia fragariae comb. nov. areproposed. Two new species, Sydowiella centaureii and Sillia karstenii, are introduced withdescriptions and illustrations. Winterella is replaced with a new genus Tortilispora typifiedby T. aurantiaca. Three new combinations are proposed in Tortilispora. We synonymizeStegophora under Lambro based on morphological similarities. An updated key for genera ofSydowiellaceae is presented.
