Roussoellaceae J.K. Liu, et al. Phytotaxa 181(1): 7 (2014)

The family Roussoellaceae, introduced by Liu et al. (2014), is characterized by immersed, gregarious, clypeate ascostromata, cylindrical, bitunicate asci and 2-celled, brown,ornamented ascospores. Wijayawardene et al. (2014) included five genera, Appendispora, Cytoplea, Neoroussoella,Roussoella and Roussoellopsis, in this family. Members of Roussoellaceae mostly occur on monocotyledons, such as bamboo and palms (Hyde et al. 1996; Hyde 1997; Liu et al. 2014). Crous et al. (2014b), however, described a new species, Roussoella acaciae, from Acacia, a dicotyledonous plant. The asexual morphs of this family are linked to Cytoplea, Melanconiopsis and Neomelanconium (Liu et al. 2014). Ariyawansa et al. (2015) reported a microconidial state occurring in the same conidiomata of Roussoella species.
