Observations on the genus <italic>Minimelanolocus</italic>, allied with descriptions of new genera, species, synonyms and new combinations.

A meticulous morphological study of the genus <italic>Minimelanolocus</italic> and related genera reveals that several species within the genus are not congeneric. As a result, two new genera, <italic>Acuminavicula</italic> and <italic>Zelofuscophialis</italic>, are proposed to accommodate <italic>Minimelanolocus chimonanthi</italic> and <italic>M. bicolorata</italic>, respectively. Additionally, a new species, <italic>M. eucalypti</italic>, is proposed. Seven species of <italic>Minimelanolocus</italic> are reassigned to the genera <italic>Kylindria, Nigrolentilocus</italic>, <italic>Pyriculariopsis</italic>, <italic>Repetophragma</italic> and <italic>Thysanorea</italic>. Two synonyms are proposed for <italic>Belemnospora verruculosa</italic> and <italic>Repetophragma dennisii</italic>. The new combination <italic>Kylindria yunnanensis</italic> is suggested based on morphological and phylogenetic analysis. A synoptic table and illustrations of conidia of accepted species are provided. [ABSTRACT FROM AUTHOR]
