Notes: Mycoenterolobium comprises four species characterized by micronematous conidiophores, gregarious, massive, flattened, fan-shaped, dark brown to black conidia (Goos 1970; Index Fungorum 2022). Mycoenterolobium resembles Cancellidium in the large, flattened conidia with rows of cells. However, they are distinguished by the arrangement of conidial rows of cells that radiate from the basal cell in Mycoenterolobium while parallel rows compact at the base in Cancellidium. The scanning electron micrograph study of M. platysporum showed its conidial development/ontogeny differed from Cancellidium (Nakagiri 1993). In addition, conidia of Cancellidium possess internal monilioid cells and the septal pores lacking in Mycoenterolobium (Ho and Hyde 2004; Zelski et al. 2014). Molecular DNA data revealed their phylogenetic placement in Dothideomycetes and Sordariomycetes, respectively (Calabon et al. 2020a; Hyde et al. 2021a).

Type species: Mycoenterolobium macrosporum J. Yang & K.D. Hyde.

Other accepted species: Species Fungorum – search Mycoenterolobium.
