Type species – Apoharknessia insueta (B. Sutton) Crous & S.J. Lee

Notes – Apoharknessia was established by Lee et al. (2004) to accommodate Harknessia insueta, and the latter constitutes a distinct phylogenetic lineage from Harknessia sensu stricto. Crous et al. (2017b) introduced A. eucalyptorum. as a second species. Marin-Felix et al. (2018) introduced a new species, A. eucalypti. This is a foliar pathogenic genus known from Brazil, Colombia, Cuba and Mauritius. Apoharknessia is similar to Harknessia but differs in having a hyaline, apical apiculus, and lacks prominent fluffy aerial mycelium in culture medium (Lee et al. 2004). In this entry, we illustrate Apoharknessia insueta.
