The species is remarkable by the large basidiomata with shallow orange yellow umbilicus, long central stipe accompanied by similar long rhizomorphs on thickened basal mycelium and large lacrymiform to sigmoid basidiospores. Macroscopically, the coarsely plicate pilei with lilac, violet to dark violaceous tints, and large distant adnate lamellae are reminiscent of the tropical African species M. bekolacongoli. The phylogenetic relationship among M. mbalmayoensis and M. bekolacongoli was assessed, extended to other species of sects. Globulares and Sicci based on DNA sequences. Phylogenetic analysis based on nuc-LSU rDNA sequence data of selected marasmioid taxa using parsimony and Bayesian analysis supported the placement of M. mbalmayoensis in Marasmius, well distinct from M. bekolacongoli, and suggested its monophyly with Amyloflagellula inflata. The findings also indicated the complexity of M. bekolacongoli.} }
