Type species: Pseudojahnula potamophila (K.D. Hyde & S.W. Wong) W. Dong, H. Zhang & K.D. Hyde, Fungal Divers (revising).
≡ Jahnula potamophila K.D. Hyde & S.W. Wong, Nova Hedwigia 68(3–4): 499 (1999).
Notes: Pseudojahnula was introduced by Dong et al. (2020) to accommodate the unstable lineage of Jahnula potamophila. This genus differs from Jahnula by hyaline to metallic grey ascomata, a several-layered peridium, comprising hyaline cells and covered with sparse hyaline hairs, obclavate asci, with an ocular chamber, and ascospores surrounded by a wavy mucilaginous sheath (Hyde and Wong 1999; Dong et al. 2020).
