In a survey of Switzerland’s natural and agricultural sites, Oehl et al. (2015) introduced a new genus Palaeospora with Palaeospora spainiae as the type species based on morphological and molecular analyses (SSU, ITS, LSU). Palaeospora differs from Archaeospora and Otospora owing to their triple-walled spores. Furthermore, the genus is distinguishable from Acaulospora due to the lack of beads on the inner wall and varies from Ambispora due to the lack of a bi-walled pedicel as ramification from the hyphal saccule neck (Oehl et al. 2015). In 2019, Schüßler & Walker (2019) analyzed all available Archaeospora sequence data and found that sequences of Palaeospora spatial clustered within Archaeospora and synonymized Palaeospora under Archaeospora, with P. spine is transferred to Archaeospora as A. spainiae (Schüßler & Walker 2019).
