Anematidium Gronchi, Boll. Ist. Sieroterap. Milan. 10(5): 242 (1931).
Index Fungorum number: IF 7153; Facesoffungi number: FoF 08580, 1 morphological species (Species Fungorum 2022), no molecular data available.
Associated with leaf spot. Sexual morph: Unknown. Asexual morph: Mycelium olivaceous, septate, branching. Conidiophores absent. Conidia catenate, in branched chains, integrated in the mycelium, cylindrical. In solid agar media, colonies olivaceous, coalescent, round, convex, with wrinkled and irregular surface, margin dark. Hyphae densely aggregated, olivaceous, branched and septate. In liquid acidic media, hyphae within the liquid media, lax, with very long branches, septate, subhyaline to olivaceous. Conidia catenate, in branched chains, integrated in the mycelium, cylindrical, branching (adapted from Videira et al. 2017).
Type species: Anematidium oxiphilum Gronchi
Notes: Anematidium is characterised by olivaceous, septate, branching mycelium, lacking conidiophores and producing catenate conidia in branched chains. Gronchi (1931) named Anematidium after the absence of conidiophores. Anematidium is inadequately known and its taxonomic status remains uncertain. The placement of Anematidium in Mycosphaerellaceae is doubtful. Fresh specimens with DNA sequence data are needed to confirm the taxonomic placement.
