Notes – Pontoporeia is saprobic on Posidonia oceanica, Suaeda monoica and Avicennia marina. This is the only genus in this family to contain more than one species. Pontoporeia is characterized by irregular peridium, filiform septate pseudoparaphyses, broadly clavate, ovate or ellipsoidal asci and ascospores with germ pore at both ends and a 2-layered wall. It is also the only member of Halotthiaceae with asci lacking an ocular chamber (see morphology Kohlmeyer & Kohlmeyer 1979, Suetrong et al. 2009, Devadatha & Sarma 2018, www/marinefungi.org).
