Assessment Notes

Taxonomic notes

Disciseda bovista was described from South America as Geaster bovista by Klotzsch in 1843. It was later combined to Disciseda by Henning i 1903. The type material is lost. Macromorphology is more or less similar in all species of Disciseda and microscopy is always needed for reliable identifications.


Why suggested for a Global Red List Assessment?

Disciseda bovista has a wide distribution in North America and Eurasia but is dependent on xerothermic grazed grasslands and steppic habitats.  Overgrowth due to ceased grazing as well as exploitation of its habitat (grazed grassland being transferred to cultivated farmlands) are detrimental factors.


Geographic range

Disciseda bovista has a wide distribution in the northern hemisphere. It is a lowland species but reaches isolated subalpine grazed grasslands (alt 450 m a s l) in S. Norway.  It has further been recorded from South America (type locality in Chile) but is absent from Africa and Oceania. The distribution is somewhat ambiguous due to misidentications with related species with similar macro-features.


Population and Trends

Currently recorded from appr. 500 occurrences (GBIF) worldwide. Based on current knowledge, a locality may house 1- 50 individuals depending on the size of the locality. Given the wide distribution range and its inconspicuous fruitbodies it is likely to have been under-redorded in suitable habitats in both the Americas and Eurasia. Estimated population size 25000 reproductive individuals + estimated unrecorded occurrences x 100? A potential decline can be suspected due to habitat loss. EOO: LC, AOO: VU

Population Trend: Uncertain


Habitat and Ecology

Disciseda bovista is a species of open, xerothermic grassland and steppe habitats, often on sandy soil.


Threats

A species of xerothermic grasslands and dry mediterranean vegetation. Overgrowth due to ceased grazing as well as exploitation of its habitat (grazed grassland being transferred to cultivated farmlands).


Conservation Actions

D. bovista is red-listed in Sweden and Norway where its reaches it northernmost distribution limit.
