Taxonomic notes

Xanthoparmelia pseudohungarica is a terricolous species close to
X. subdiffluens Hale and X. camtschadalis (Ach.) Hale. All have
typically terricolous, vagrant or loosely adnate thalli that lack vegetative propagules, identical medullary chemistry, weakly or
strongly convolute lobes with a brown lower surface and a weakly to markedly white maculate upper surface. Differences among these three species are subtle and overlapping. For a detailed comparison among these three species see Pérez-Ortega & Elix (2007).

Why suggested for a Global Red List Assessment?

The species shows a scattered distribution occurring in few localities of Spain, Hungary, Czech Republic, Russia, Mongolia and Ukraine. It is associated to calcareous soils in dry steppic and continental areas. Small populations sizes in some parts of its distribution.

Criterion A. There is no information about trends in population size over time for the whole distribution area. Data is only available for Hungary where the number of records after 1975 are scarce (two) compared to those before 1975 (>30) (Farkas & Lőkös 2006) and Ukraine. One out of four localities are extinct from Ukraine (Khodosovtsev et al. 2013).
Criterion B. The extent of occurrence (EOO) has been calculated in 541,046.482 km2 using the GeoCat tool. Likewise, the area of occupancy has been calculated in at least 44.000 km2 what is out of threathened threshold. Thus, the species would be assesses under criterion B as LC.
Criterion C. Information about the number of mature individuals or population size is not available. This criterium does not apply.
Criterion D. No information about total number of mature individual is available. This criterium does not apply.
Criterion E. Quantitave studies about the risk of extinction have not been carried out in this species. This criterium does not apply.
The species may be assessed as Least Concern.


Geographic range

Only known from scattered steppic localities in Mongolia (Huneck et al. 1992), Russia, Hungary (Farkas & Lőkös 2006), Czech Republic?, Montenegro (Hawksworth et al. 2008), Kazakhstan, Ukraine (Khododovtsev et al. 2013) and Spain (Pérez-Ortega & Elix 2007).


Population and Trends

Data is only available for Hungary where the number of records after 1975 are scarce (two) compared to those before 1975 (>30) (Farkas & Lőkös 2006). One out of two localities are extinct from Ukraine (Khodosovtsev et al. 2013).

Population Trend: Deteriorating


Habitat and Ecology

Continental and steppic dry localities with calcareous soils. Also found recently in acid soils in Hungary (Dr. Edit Farkas, pers. comm.) and overgrowing siliceous stones in Spain.


Threats

Major threats are grazing, trampling and habitat dissapearence. Farkas & Lőkös (2006) points to a reduction of populations in Hungary due to a drier climate.


Conservation Actions

No conservation actions are known.


Research needed

1) It would be neccessary to estimate the population sizes of the different disjunct locations where the species occur. 
2) Estimation via genetic analyses of past and present connectivity among disjunct populations.
3) Estimation of future distribution in future scenarios of climate change.
