Résumé (anglais) : Chaetomium convolutum, newly isolated from herbivore dung in a survey of coprophilous ascomycetes and basidiomycetes, is first described from Italy and compared with other species of the so called “group-bostrychodes”. The taxonomic uncertainty, still present in this group despite a recent comparative, morphological and molecular study, led the author to revise all Italian collections of species related to C. convolutum, and to prove that also the very rare C. hexagonosporum is present in Italy. The morphological features of C. hexagonosporum are described in detail and particularly compared with those of C. convolutum. The results of this review confirm the existence of several intermediates in the group-bostrychodes, for which a much more extended revision is hoped
