Notes – The genus was found on mangrove wood and its type species was Pleospora avicenniae by Borse (1987). Pleospora avicenniae was transferred to Julella by Hyde (1992c). The type species Julella buxi Fabre has 2-spored asci and lacks a well-developed apical apparatus, while asci of J. avicenniae are 8-spored and have an unusual, distinct, apical apparatus. Phylogenetically, J. avicenniae formed a monophyletic clade in the Pleosporales with high support (Suetrong et al. 2009, Zhang et al. 2012b, Ariyawansa et al. 2013a, Jones et al. 2019a). Ariyawansa et al. (2013a) introduced a new genus Halojulella to accommodate Julella avicenniae (current name Halojulella avicenniae), in a new family Halojulellaceae.
