Diversispora C. Walker & A. Schüssler emend. Tedersoo & Magurno

Type species.

Diversispora spurca (C. M. Pfeiffer, C. Walker & Bloss) C. Walker & Schüssler.

Description.

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).
