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 as 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. 

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

Other accepted species: Species Fungorum – search Apoharknessia.
