Description
editSetoidium murrayae was described on Murraya paniculata, a host species belonging to Rutaceae, with unusual anamorphic characteristics. The conidia were formed in chains and contained fibrosin bodies. The mycelium formed filiform to rarely falcate special aerial hyphae (similar to those of Cystotheca species). Therefore, this anamorphic species was reallocated to Setoidium by Braun and Cook in 2012.[1]
Taxonomy
editThe fungus was formally described in 1992 by Hosag., Uwe Braun and Rabindran with the basionym Oidium murrayae. The holotype was collected in India. The specific epithet derives from the name of the genus Setoidium murrayae infects. Braun and R.T.A. Cook reassigned this species to Setoidium in 2012. The phylogenetic affinity of this species is unclear, particularly given that the host plant does not belong to Fagaceae. Bradshaw et al. (2023) say that sequence analyses are necessary but the holotype is missing.[2]
