Roussoella Sacc., Atti Inst. Veneto Sci. lett., ed Arti, Ser . 6 6: 410 (1888)
Notes.
the genus Roussoella was introduced by Saccardo et al. (1888), with R. nitidula Sacc. & Paol. as the type species, which was collected from bamboo in Malaysia. This family is characterised as having semi-immersed to immersed, solitary or gregarious, clypeate ascostromata containing trabeculate pseudoparaphyses embedded in a gel matrix, long cylindrical to clavate bitunicate asci with or without obvious fissitunicate dehiscence and brown, 2-celled ornamented ascospores (Liu et al. 2014). In this study, we introduce three new records of Roussoella species, based on morpho-anatomical and molecular analyses (Fig. 2).
