Diversisporaspurca (C.M.Pfeiffer, C.Walker & Bloss) C.Walker & Schüssler.

Spores diversisporoid, rarely otosporoid or tricisporoid. Diversisporoid spores formed singly, in clusters or in large disorganised fruiting bodies with high spore numbers. Spores with 1–4 wall layers; pores often closed with a septum. Subtending hyphal pores rarely open. Otosporoid spores formed laterally on the persistent neck of a sporiferous saccule. Tricisporoid spores with inner flexible hyaline wall layers (formed de novo) without granular beaded surface and no Melzer reaction. Spore pores generally closed by a septum at the spore base, arising from the innermost wall lamina or inner layer or from both. Forms a monophyletic group within Diversisporaceae based on the SSU-ITS-LSU phylogram (Fig. 1, Suppl. material 1).
