Notes: The genus Halosphaeria comprises H. appendiculata Linder as the type species. Other species assigned to the genus by Kohlmeyer (1972) have been transferred to other genera as the result of ultrastructural and molecular studies: Antennospora, Halosphaeriopsis, Lautisporopsis, Okeanomyces, Ondinella, and Remispora (Jones et al. 2009, 2015).
