Saccardo (1880a) introduced Robillarda to accommodate the type species R. sessile. This genus is characterized by flexuous, narrow tubular, aseptate appendages and holoblastic conidiogenous cells, proliferating sympodially or percurrently near the apex (Crous et al. 2015, Wijayawardene et al. 2016). Tennakoon et al. (2021) is used for the treatment of this genus. In this paper, we introduce one novel Robillarda species from a freshwater habitat in Thailand. 

Type species: Robillarda sessilis (Sacc.) Sacc., Michelia 2(no. 6): 8 (1880).

Other accepted species: Species Fungorum – search Robillarda.
