NOTA: All members of this genus have been transferred to Amanita by Justo (Justo et al. 2010).

The species of Torrendia Bres. are (1) secotioid; (2) expand from within a membranous, universal veil; (3) have longitudinally acrophysalidic stipe tissue (as in Amanita); (4) have inamyloid spores (with one possible exception); and (5) have clamps on the bases of their basidia (with the same possible exception). Taxa of the Mediterranean region andAustralia have been assigned to Torrendia.  At least some of the taxa of this genus (including the type species) appear to have had ancestors in common with species of Amanita section Caesareae [ key (over 540 Kb PDF) ].  As in the case of Amarrendia (above), the status of the genus Torrendia is under on-going investigation.  At present, the editors of these pages favor recombination of all taxa of Torrendia in Amanita.  It is very likely that the species of Torrendia are unlikely to share a common ancestor that is not also the ancestor of numerous other species in both subgenera of Amanita—species with both amyloid and inamyloid spores have been reported for Torrendia.

The type species of Torrendia is T. pulchella Bres. (1902).  See Malençon (1955), Bas (1975), Miller and Horak (1992), Tulloss (2005b).
