The Dutch Mycological Society has named Clavaria argillacea its Mushroom of the Year 2019, as reported on 20 March 2019.
The species used to be common in the Netherlands in the 1930s. About 1980, it had become threatened because of acid rain. Since then, there have been some measures against acid rain. Things are a bit better for Clavaria argillacea now. It is considered no longer ‘endangered‘, but ‘vulnerable‘.
