Macrohilaceae Crous

Citation when using this data: Hyde KD et al. 2020 – Fungalpedia, Ascomycota.

Index Fungorum, Facesoffungi, MycoBank, GenBank.

Classification: Diaporthales, Diaporthomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Endophytic or saprobic on leaves of Myrtaceae (dicotyledons). Sexual morph: Undetermined. Asexual morph: Coelomycetous. Conidiomata pycnidial, immersed, becoming erumpent, medium brown, globose to irregular. Conidiomata wall composed of pale brown-walled cells of textura globulosa. Conidiophores reduced to conidiogenous cells. Conidiogenous cells pale brown, cylindrical, percurrently proliferating at the apex with annellations. Conidia brown to dark brown, 1-septate, slightly constricted at septum, apex rounded, base flattened with a protruding hilum (adapted from Maharachchikumbura et al. 2016b).

Notes: The type species of Macrohilum, M. eucalypti formed a distinct phylogenetic lineage in Diaporthales, thus Crous et al. (2015a) introduced Macrohilaceae to accommodate it. Subsequent publications by Maharachchikumbura et al. (2015, 2016b), Wijayawardene et al. (2016b, 2018a) and Senanayake et al. (2017a, 2018) accepted Macrohilaceae as a well-established family within Diaporthales and basal to Diaporthaceae. Currently, Macrohilaceae comprises only one genus.

Type genus: Macrohilum H.J. Swart
