Classification: Lepidostromataceae, Lepidostromatales, Agaricomycetidae, Agaricomycetes, Agaricomycotina, Basidiomycota, Fungi.

Ertzia (Lepidostromataceae) was established by Hodkinson et al. (2014) with the type species Ertzia akagerae, previously identified as Multiclavula akagerae, and Lepidostroma akagerae (Fischer et al. 2007, Ertz et al. 2008). Later, Hodkinson et al. (2014) revised and proposed a new genus Ertzia based on morphological characteristics comparison and phylogenetic analysis. The distinctive characteristics of Ertzia is the microsquamulose thallus forming contiguous glomerules with a cortex of characteristic, jig-saw-puzzle-shaped cells and lacking medulla. However, photobionts have not yet been identified. Basidiomata clavarioid, unbranched to very rarely branched. Basidiospores ovoid (Fischer et al. 2007, Ertz et al. 2008).

Type species: Ertzia akagerae (Eb. Fischer, Ertz, Killmann & Sérusiaux) Hodkinson & Lücking

Other accepted species: This genus is monotypic.
