Taxonomic notes: This species is represented by a single sheet in TCD, labelled "336. KGS", as shown in Fig. 108E. The trichoblast branches do not show adherent walls (as in Dasya) so it is probably a Micropeuce, with 5 pericentral cells. In form it is similar to M. feredayae, but its identity needs to be established on the basis of similar collections from the King George Sound region.

Species of uncertain status.
