Assessment Notes
Taxonomic notes
Geastrum saccatum Fr. was described from South America. No type material exists and it has so far not been neotypified. Morphological and molecular data .indicate a certain variability and a cryptic speciation is likely.
It has in some countries been considered a synonym of G. michelianum (G. triplex ss. auct europ.). Zamora et al. (2014)
place these species in different subsections of Geastrum, indicating that they are indeed separate species.
Why suggested for a Global Red List Assessment?
Although redlisted in several European countries it should, judging from the large population and the cosmopolitan distrubution to be of least concern. However, the potential existence of cryptic speciation makes the global red-list evaluation difficult. Suggested DD
Geographic range
Cosmopolitan (NB potential species complex). Thermophilous and avoids boreal and Arctic-alpine environments.
A number of records from the UK refer to G. michelianum according to photos submitted to iNaturalist.
Population and Trends
More than 5000 records and a world wide distribution according to GBIF. However, these records may refer to cryptic species in the G. saccatum agg., making estimations of populations and trends uncertain.
Population Trend: Uncertain
Habitat and Ecology
A saprotrophic species occurring in wooded habitats. In northern Europe restricted to warm and dry woodland on calcareous soil, also under bush in parks and gardens (Syringa). In central Europe in sandy deciduous, steppic woodland, often under Robinia. It further occurs (but less frequent) in dry calcareous grasslands and sand dunes.
It has a wide ecology and is apparently also present in subtropical/tropical vegetation (described from Brazil by Fries 1829), but the possibility of a species complex should be kept in mind.
Threats
Although redlisted in several European countries it should judging from the large population and the cosmopolitan distrubution be of least concern. However, the potential existence of cryptic speciation makes the global red-list evaluation difficult.
Conservation Actions
Redlisted in some European countries:
Sweden - EN(C)
Czech Republic EN(D1)
Poland - E
Research needed
The taxonomy of Geastrum saccatum s. lato should be investigated.
