The species is known from four (4) localities, one located on the territory of Galicica NP. The number of registered individuals is about 100, while the total number of mature individuals (including those that are extant but not yet recorded) is not expected to reach 1,000, therefore this is treated as a very small population.
In our country, Greek juniper is the primary host, and on Golem Grad Island it is located within a protected area but in the vicinity of Calakli village, it is under intense anthropogenic impact. This is a threatened area since there is mass exploitation of juniper trees by the inhabitants. Fires during summer season pose another severe threat. АОО is 24 км2 but it also includes sites with well-developed Greek juniper communities, which are much widely distributed, and where the species is expected to occur.


Current population trend



Mycena juniperina is a rare species, occurring with different abundance at all known
localities but it is more common in the well-developed Greek juniper communities,
particularly if there are old trunks around. The highest number of specimens has been
observed at localities with well-developed Greek juniper communities, such as the
locality in the vicinity of Calakli village, where circa 50 specimens have been recorded,
and Golem Grad island with about 30 specimens. On the remaining two sites – Vodno
Mt and Jasen Nature Reserve, Mycena juniperina has been sighted only once, with
around 10 specimens on each of the sites.

Habitat and Ecology

Mycena juniperina grows on bark of Juniperus communis L. in northern Europe, Poland and Italy. In recent years, it has been demonstrated that M. juniperina is able to inhabit other Juniperus species. It also grows on the bark of J. excelsa (Doğan & Karadelev
2006; Doğan et al. 2011), J. oxycedrus (Pérez-De-Gregorio i Capella et al. 2009; Fridlender & Louis 2010), J. foetidissima (Doğan et al. 2011) and J. phoenicea (Moreau et al. 2007; Konstantinidis 2012). In N. Macedonia, the species has been spotted on bark of living Greek juniper (Juniperus excelsa). Greek juniper forests are considered as a priority habitat in the Habitats Directive, specified as: *Endemic forests with Juniperus spp. – Pal. 42.A3 – Greek juniper woods (Juniperetum excelsae) – forest formations dominated by Juniperus excelsa. The species seldom occurs on bark of older trees of Juniperus oxycedrus. The altitude of the localities where Mycena juniperina has been collected is between 120 and 900 m.

Use and trade

Use and trade

There is no confirmed use and trade of this species in N. Macedonia.



The impact is manifested by host habitat degradation and/or fragmentation in view of the primary host specialisation. Immediate impact upon the species has not been ascertained. The threat manifests in different ways, and it depends on the community site. It is minor in the protected localities within Galicica NP while it is major in the surroundings of Chalakli village where there is mass exploitation of juniper trees by the local inhabitants. For all habitats: fires during summer season could pose another severe threat. Intensive agriculture is a minor threat to biodiversity in juniper forests in the area of concern.
