Xeromphalina junipericola is a wood-inhabiting very rare fungus known only from three European countries; Macedonia, Spain and Turkey. The species´sporocarps are only recorded from old trees. In Macedonia it grows exclusively on stump of Juniperus excelsa, in Spain on J.turifera and J.oxycedrus, while in Turkey it grows on J.foetidissima and excelsa. The known populations are very small.

Moreno & Heykoop (1996) described this species from Guadalajara province in Spain.
Xeromphalina junipericola is a rare endemic fungus to Europe and only known from a small number of localities in three Mediterranean countries; from Spain (Guadalajara), Macedonia and central and southern Turkey.
Xeromphalina junipericola is a very rare species known only from Macedonia, Spain and Turkey. The known populations are very small. Updated number of known occupied trees in Mediterranean region = 50 (estimation <100 occupied trees in total), =200 functional individuals. A search of 50 sites in Turkey with apparently suitable trees only yielded 6 occupied trees (Dogan pers obs.) suggesting that the number of unknown sites is not very large. In Macedonia, 9 searched sites with only one occupied tree.
Evaluation: Globally - VU
Population Trend: Uncertain
Xeromphalina junipericola grows on trunks of Juniperus spp. It is apparently restricted to Juniperus and known from J. oxycedrus and J. thurifera in Spain (Garcia-Manjon & Moreno, ). In Turkey it was collected on trunks of J. foetidissima and J. excelsa and in Macedonia on J.excelsa. It is likely that X. junipericola prefers J. foetidissima and J.excelsa as its main hosts in Eastern Mediterranean (Macedonia and Turkey).
[(Heykoop & Moreno (2007) and Moreno et al. (2002)] and on Juniperus oxicedrus. Later the species was published from central and southern part of Turkey and Macedonia on different juniper trees (Dogan & Karadelev (2009).
In Macedonia it grows exclusively as a saprobe on stump of Juniperus excelsa, in Spain on Juniperus turifera and Juniperus oxycedrus, while in Turkey on Juniperus foetidissima and Juniperus excelsa.
The species is associated with old growth juniper trees and reduced amount of habitat is the main cause of the inferred decline and threat. The small population size make the species very susceptible for local extinction due to random events such as fires, tourism, destruction of habitats and other human activities. In Macedonia there is mass exploitation of juniper trees by the inhabitants. They burn branches for production of burnt lime.
Protection of known localities together with appropriate management plans are the main actions needed. National Forest Services and other regional organizations should be informed about the need of conserving old juniper trees.
