Assessment Notes

Taxonomic notes

Spores of Archaeospora trappei most resemble those of Intraspora schenckii (Sieverd. & S. Toro) Oehl & Sieverd. Both species form hyaline spores of an identical subcellular structure. However, spores of A. trappei form laterally on the neck of a sporiferous saccule, and those of I. schenckii develop inside the neck (Sieverding; Oehl 2006).

Why suggested for a Global Red List Assessment?

Due to the several records worldwide, we suggest this species to be categorized as Least Concern (LC).
