Name refers to Eucalyptus, the host genus from which this Notes — Anungitea is characterised by having an apical co- fungus was collected. nidiogenous cell with conspicuous denticles, while Anungitopsis Classification — Microthyriaceae, Microthyriales, Dothideo- has indistinguishable scars arranged in a rachis (Seifert et al. mycetes. 2011). Neoanungitea has a rachis much like Anungitopsis, but has conspicuous flat-tipped sympodial loci, somewhat resem- Mycelium consisting of hyaline to pale brown, smooth to ver- bling Anungitea.
