Justification

The species is known from several localities, one of them located in Jasen nature reserve, which is a protected area. The other sites are not protected, and the habitats are under anthropogenic pressure. The total number of recorded individuals is about 50. The impact is manifested by host habitat degradation and/or fragmentation caused by logging given that the species is commonly bound to a single host. Fires during summer season are another serious threat. Nevertheless, beech communities are widely distributed in the country; thus the predicted number of specimens would be approximately 500.

Population

Current population trend

Decreasing

Description

Dentipellis fragilis is a rare species occurring with varied abundance at all stations where the host develops but it is more common in the well-developed beech communities, particularly if there are old trunks around. The species is found individually or with a few fruiting bodies on all known sites, and the number of known fruit bodies is minor, totaling approximately 50 specimens. Nonetheless, one should bear in mind that beech forests are widely distributed in the mountainous regions in the country, which is the reason why the projected number of specimens would be as a minimum ten times the current number.

Habitat and Ecology

Dentipellis fragilis is a resupinate species with long straight spines forming long patches on the underside of logs. It is a saprobe of heavily decayed deciduous trees and it causes white-rot. It prefers moist and shady growth sites, such as the undersides of large fallen trunks. A characteristic environment is a luxuriant thicket or grass-herb forest, and the species is slightly hemerophilous. D. fragilis strongly favours the trees of the genera Fagus and Quercus, and its occurrence on other frondose trees, such as Carpinus, Tilia, Acer, Alnus and Populus tremula, appear to be rather sporadic.

In N. Macedonia, the species has been observed on old beech trunks (Fagus sylvatica), and there is a single case on Acer pseudoplatanus. Nearly all data are derived from old beech trunks where the species grows as a saprobe triggering a white-rot. Beech forests are found in all mountains in N. Macedonia, and they develop in the height belt of 1,100-1,650 m above sea level. Almost all data originate from heights above 1,000 m. It is only in Stogovo Mt that Dentipellis fragilis has been collected from a fallen trunk of Acer pseudoplatanus, in mixed woods of Alnus, Corylus and Acer pseudoplatanus.

Use and trade

Use and trade

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

Threats

Threats

The impact is manifested by host habitat degradation and/or fragmentation in consideration of the fact that the species is generally bound to a single host. Immediate impact upon the species has not been ascertained. With the exception of the piece of data from Jasen nature reserve, all the remaining stations are outside the boundaries of protected areas. This implies that the species is under heavy anthropogenic impact due to logging of beech woods. The threat manifests differently, and it is contingent on the community site but fires during summer season could pose another severe threat.

Conservation actions

Conservation actions

Protection of old host trees is the crucial conservation action for species protection; study of the population number and range; interpretation of species status by means of enhanced understanding of the species biology and ecology; habitat conservation; study of the trends via monitoring.
