Belongs to a species complex also including the North American T. cretaceum and two or three hitherto undescribed species occurring in arid regions on the Eurasian continent (Jeppson et al. 2017, Finy et al. 2023).
Small population in a rare habitat. Occurrences restricted to a small, well investigated area in Central Hungary. Most localities now protected by law (National Park) but a considerable historical habitat loss due to changing land use turning the steppe landscap into arable land has had a negative influence on its population.
Also threatened by abandoned grazing and desertification of habitats as a consequence of global warming.
A protected species in Hungary.Suggested assessment: EN-VU (A), NT(D1) or EN(B)?
Only known from a restricted area in Hungary (Pannonian steppe biome).
Known from less than 10 occurrences in a restricted area east of the Danube (Central Hungary).
EOO: 600 km2
AOO 24 km2Its habitat in Central Hungary is welll investigated during the last 20 years and its “dark number of occurrence” is relatively low. Records of similarly looking samples from other arid areas (eg Kazakhstan, and south/central Spain) belong to closely related and hitherto undescribed species (cfr Finy et al. 2023).
Estimated number of localities: 50
Estimated number of mature individuals: 1000
Population Trend: Decreasing
Saprotrophic in pannonian sand steppe vegetation. Occurs in areas with naked, often wind-blown sand under extreme arid conditions.
Small population
Geographically restricted EOO
The habitat has a restricted distribution
Historical and ongoing decrease of sand steppe habitats (transfer into arable land)
Overgrowth of sand steppe habitats due to abandoned sheep-grazing.
Desertification as an effect of global warming.
Legally protected species in Hungary.
Actions needed:
Maintaining traditional land use.
Regular monitoring of known localities
