Assessment Notes
Taxonomic notes
According to Index Fungorum (19.03.2019) it should be named Imperator torosus (Fr.) Assyov, Bellanger, Bertéa, Courtec., Koller, Loizides, G. Marques, J.A. Muñoz, Oppicelli, D. Puddu, F. Rich. & P.-A. Moreau
Why suggested for a Global Red List Assessment?
It is a rare, large and beautiful bolet with mainly Mediterranean distribution. It seems to be restricted by old-growth broadleved forests dominated by beech and oaks, on well-drained calcareous soils. Such landscapes are declined in all parts as a result of human activity.
Geographic range
In Russia it is known only from one locality in the Western Caucasus, on the territory of Caucasian State Biosphere Reserve.
Population and Trends
Population Trend: Uncertain
Habitat and Ecology
Forms ectomycorrhiza with Quercus and Fagus spp. Occurs in broadleaved and mixed forests on well-drained usually calcareous soil. Fruit bodies more often appear in the warmest season (at least in the Western Caucasus), presumably thermophilous species.
Threats
cutting of old-growth forest dominated by oaks and beeches.
Conservation Actions
In Russia it is protected on regional level (Republic of Adygeya) and preserve in Caucasian State Reserve.
Research needed
