Taxonomic notes

Synonym: Torrendia pulchella Bres.

Why suggested for a Global Red List Assessment?

Amanita torrendi has a restricted global distribution.

Geographic range

It is so far reported from four countries in Europe (notably Spain, but also Portugal, France and Italy), two countries in Africa (Morocco and Algeria), and one in Asia (Turkey), a typical distribution around the Mediterranean Sea basin.  There is an additional single occurrence reported in Sierra Leone from 1905.

Population and Trends

By 2015, the number of known sites was reported to be around 100, of which 90 % are located in Spain (Fraiture & Otto, 2015).

GBIF - 175 occurrences (Spain, 136; Portugal, 30; Morocco, 4; France, 2; Sierra Leone, 1).

Population Trend: Uncertain

Habitat and Ecology

Amanita torrendii is a typical Mediterranean species that occurs only in Mediterranean and sub-mediterranean forests and shrublands. It is ectomycorrhizal with Pinus spp. (P. pinaster and P. pinea), Quercus spp. (notably Q. suber), Cistus spp. and, possibly, also with Castanea sativa.

Habitats include forests/woodlands, dunes, macchia and garrigues in the following NATURA 2000 habitats:

2180 - Wooded dunes of the Atlantic, Continental and Boreal Region
2270 - Wooded dunes with Pinus pinea and/or Pinus pinaster
9230 - Galicio-Portuguese oak woods with Quercus robur and Quercus pyrenaica
9260 - Castanea sativa woods
9330 - Quercus suber forests; common habitat
9340 - Quercus ilex and Quercus rotundifolia forests; common habitat
9540 - Mediterranean pine forests with endemic Mesogean pines
