Assessment Notes
Justification
It is currently (2021) known from ca 570 locations (gbif.org), number of mature individuals is 10fold higher ca 5700. Estimated population size may be 5-fold higher, up to 28500 mature individuals. There is no clear evidence of populations decline, except in Netherlands (EN). Red-listed in Nordic counties: Denmark (VU), Estonia (CR), Finland (VU), Norway (CR) and Sweden (EN).
Taxonomic notes
Why suggested for a Global Red List Assessment?
Chamaemyces fracidus is a lepiotoid fungus growing on nutrient-rich or calcareous soils in forests. It is widespread in Europe, although rare and local everywhere, very rare in the northern countries, where is red-listed as threatened.
Geographic range
Chamaemyces fracidus occurs in whole Europe and is reported in Asia (Israel), although is rare in the northern countries. Everywhere rather rare and local, absent from the boreal zone.
Population and Trends
Almost all localities are situated in Europe and only one record is in Asia (Israel). It is currently (2021) known from ca 570 locations (gbif.org), number of mature individuals is 10fold higher ca 5700. Estimated population size may be 5-fold higher, up to 28500 mature individuals. There is no clear evidence of populations decline, except in Netherlands (EN).
Chamaemyces fracidus is red-listed in Nordic counties: Denmark (VU), Estonia (CR), Finland (VU), Norway (CR) and Sweden (EN).
Preliminary assessment: LC.
Population Trend: Stable
Habitat and Ecology
Presumably saprotrophic, on nutrient-rich or calcareous soils in forests and grasslands, often along path-sides or tracks.
Threats
The main threat is clear cutting and deterioration of habitats.
Conservation Actions
Conservation actions is needed in known sites.
Research needed
Taxonomical and distribution studies of other morphologically similar Chamaemyces taxa is needed: C. carmelensis M. Didukh & Wasser described from Israel (Didukh et al. 2004) and C. pseudocastaneus (Bon & Boiffard) Contu (1990) from Mediterranean regions (synonym: C. fracidus var. pseudocastaneus).
Use and Trade
There is no use and trade known.
