Classification: Ascomycota genera incertae sedis, Fungi.

Viridiannula was introduced by Etayo (2002a) to accommodate the type species V. pertusariae which grows on Pertusaria. This genus is characterized by sessile conidiomata, 40–50(–70) μm diam. Conidiogenous cells are polyphialidic, with 1–4 proliferations, conidia are polymorphic, 6.5–10(–12) × 2.5–3(–3.5) μm (Etayo et al. 2024). Due to the absence of molecular data, Viridiannula is tentatively placed within Ascomycota genera incertae sedis, pending further phylogenetic analysis (Hyde et al. 2024).

Type species: Viridiannula pertusariae Etayo, on Pertusaria (Etayo 2002a).

Other accepted species: Species Fungorum – search Viridiannula.
