Type species – Thyridariella mangrovei Devadatha, V.V. Sarma, K.D. Hyde, D.N. Wanas. & E.B.G. Jones, Mycol. Progr. 17 (7): 798 (2018).

Notes – Thyridariella was introduced to accommodate two marine species, T. mangrovei and T. mahakoshae which are regarded as saprobes on decaying wood of Avicennia marina (Devadatha et al. 2018b). The genus is primarily characterized by semi-immersed to immersed, globose to subglobose, ostiolate ascomata with reddish brown neck, clavate asci with moderately long pedicel and hyaline, muriform, fusiform to ellipsoidal, guttulate ascospores with a mucilaginous sheath (Devadatha et al. 2018b). Thyridariella species resemble Parathyridaria as both genera have a lateral thickening of the ostiolar neck and guttulate ascospores (Jaklitsch & Voglmayr 2016, Devadatha et al. 2018b). However, Parathyridaria has pale to greyish brown ascospores that are occasionally muriform while Thyridariella has hyaline, muriform ascospores (Jaklitsch & Voglmayr 2016, Devadatha et al. 2018b). Phylogenetically, T. mangrovei and T. mahakoshae clustered together with strong support and formed a sister relationship with Cycasicola and Liua (Devadatha et al. 2018b, Phookamsak et al. 2019).
