Type species – Mauginiella scaettae Cavara, Atti R. Accad. Naz. Lincei, Mem. Cl. Sci. Fis., sér. 6 1–2: 65 (1925).
Notes – The pathogenic genus Mauginiella was accommodated in Phaeosphaeriaceae by Wijayawardene et al. (2017a,b, 2020). The genus is represented by its hyphomycetous asexual morph and is characterized by white colony, composed of branched, hyaline, septate, immersed to superficial hyphae, abundant sporulation, homogeneous with powdery appearance. Arthroconidia are hyaline, glistening white in mass, aseptate to 6-septate, arising from 1- to multi-septate, segmented aerial hyphae (Cavara 1925, Abdullah et al. 2005). The genus was reported as a causal agent on inflorescence rot of date palm in many palm-growing countries (Abdullah et al. 2005, El- Deeb et al. 2006, Abed et al. 2019). Phylogenetic analyses obtained in this study shows that the genus belongs to Phaeosphaeriaceae.
