Notes – Iodosphaeria was placed in Amphisphaeriaceae by Samuels et al. (1987) and also accepted by Eriksson et al. (2001). However, Barr (1994) and Hyde (1995d) suggested this genus should be placed in Lasiosphaeriaceae. Kang et al. (1998, 1999a) and Jeewon et al. (2003b) suggested that Iodosphaeria should be excluded from Amphisphaeriaceae and the genus was transferred to Trichosphaeriaceae (Réblová 1999d). Hilber & Hilber (2002) introduced Iodosphaeriaceae and treated. Iodosphaeria aquatica was excluded from Iodosphaeria based on morphology being similar to Pseudohalonectria lignicola (Hsieh et al. 1997b). Iodosphaeria tongrenensis was introduced by Li et al. (2015a) from China with morphology and molecular evidence. Iodosphaeria honghense was introduced from China by Marasinghe et al. (2019) and is illustrated here.
