Fig. 1. Rhachisphaerella mozambica (CBS 122464; redrawn from Mycosphaerella mozambica Fig. 6 in Arzanlou et al. 2018). a. Ascus with biseriate ascospores. b. Ascospore germination pattern. c.

Importance and role

Importance of genus to ecosystem

Species of Rhachisphaerella are saprobic or pathogenic on host plant. As saprobes, they can help in nutrient recycling in the ecosystem. As pathogen, they may cause lesions and leaf spot on host plants (Jacome et al. 2003).


Industrial relevance and applications

No industrial use of Rhachisphaerella have been reported.

Quarantine significance

No biocontrol agent from Rhachisphaerella has been investigated. Rhachisphaerella may have the potential to control some pathogen. Further studies are needed.


Biochemical importance of the genus, chemical diversity or applications

Rhachisphaerella may produce important compounds and toxins responsible for blight and spots on the host. Further studies are needed for identification of those chemicals.


Diversity of the genus

Rhachisphaerella comprises only one species known on Musa sp. (Musaceae) in Mozambique. The diversity of the genus Rhachisphaerella is still only poorly understood, and the lineages described so far likely represent only a small fraction of the true diversity of Rhachisphaerella. Numerous new taxa remain to be described.
