Diagnosis.

Differs from other species of Pseudoentrophospora and Entrophospora based on the ITS region (ITS2 positions 127–146 gaaccgcaaattacgcatta, one mismatch allowed) and LSU (positions 486–515 gaacaggtcaacatcaattcttattgccat, one mismatch allowed) as indicated in Fig. 3.

Type.

Soil eDNA sample TUE101916 (holotype); eDNA sequence EUK1631429 (lectotype); GSMc plot G4940, coppiced Juniperus-Acer woodland (soil sample TUE001916) in Kesse Island, Estonia, 58.63443°N, 23.43938°E.

Description.

Other eDNA sequences EUK1636430–EUK1636432 from the type locality.

Etymology.

pseudo (Greek) = false; Entrophospora (Latin) refers to a related fungal genus; and kesseensis (Latin) indicates locality of the type species. The name depicts phylogenetic relatedness to Entrophosphora and the only locality where the type species has been recorded.

Notes.

Found from a single site, with ITS and LSU sequences differing up to 0.5% and 1%, respectively. The ITS1 subregion harbours only 58 bases, being amongst the shortest across fungi (excl. microsporidians).
