Coprinus comatus is globally widespread edible saprobic fungus and there is no evidence of decline: it can be locally abundant where suitable habitat exists. Therefore, it is assessed as Least Concern (LC).
Why suggested for a Global Red List Assessment?
This species has a global distribution. It is widespread in Europe, Asia and North America and is common in suitable habitats. In addition, present in Africa, South and Central America, Australia and New Zealand. The area of occupancy (AOO) of this species is much larger than 2,000 km², and its extent of occurrence (EOO) is much larger than 20,000 km².
Population and Trends
The population size is likely to be very large since this is such a widespread species and more or less stable. There is no indication of any decline.
Population Trend: Stable
Habitat and Ecology
A common decomposer fungus often seen growing in man-made habitats such as lawns, along gravel roads and waste areas. It grows in groups in places which are often unexpected, such as green areas in towns. It occurs widely in grasslands and meadows in Europe and North America. It appears to have been introduced to Australia, New Zealand and Iceland.
There are no major threats to this species. It is commonly and widely found in urban areas and other disturbed or man-made habitats.
No conservation measures are needed for this species since it is widespread and there are no major threats.
Use and Trade
Collected as an edible fungus world-wide (Boa 2014). It is reported to be delicious if collected young and eaten soon after being collected. Classified as suitable for commercial marketing in the Nordic countries (Gry et al 2012). The species is cultivated in China as food.
