Assessment Notes

Taxonomic notes

Syn. Geastrum nanum Pers.


Why suggested for a Global Red List Assessment?

Redlisted in some European countries (habitat decline associated with abandoned grazing). Large, cosmopolitan population. Suggested: NT(A) on a European level; globally LC?


Geographic range

Cosmopolitan distribution; not present in boreal and Arctic-alpine areas. Northernmost record in Central Norway.


Population and Trends

Currently more than 4000 records on GBIF. Cosmopolitan distribution.

EOO: 98 000 000 km2
AOO appr. 1000 km2

Trend in Europe slowly declining due to habitat loss. Population trends on other continents unclear.

Population Trend: Stable


Habitat and Ecology

Saprotrophic in grazed dry grassland, sand dunes, sandsteppe, sometimes in needle beds under Juniper bush in open and exposed sites. One record from a grazed subalpine south-facing grassy slope in Central Norway (northernmost record). Can be very abundant in its localities. Needs a low and sparse field layer and is favoured by moderate soil disturbance from grazing cattle. Thermophilous and calciphilous. Occurs both inland and along coastlines.


Threats

Habitat decline as grazing is abandoned or calcareous grasslands are turned into arable land.
