M. bannaensis M. minor M. minuta M. setulosa Megasporoporia is a genus of four species of crust fungi in the family Polyporaceae.
The genus was circumscribed by mycologists Leif Ryvarden and Jorge Eduardo Wright in 1982, with Poria setulosa as the type species.
[2][3][4][5][6] Molecular analysis showed that Megasporoporia nested within the "core polyporoid clade", a grouping of polypore fungi roughly equivalent to a more narrowed but still broad concept of the family Polyporaceae.
[9] Megasporoporia have crust-like fruit bodies, with large or small pores, and spores that are typically greater than 10 μm long.
Characters that can be absent or present in the hymenium include small rhomboid or bipyramidic crystals, dendrohyphidia, hyphal pegs, and cystidioles or cystidia.
