This video is about Leucopaxillus paradoxus fungi.
The Dutch Mycological Society reports that on 9 November 2013 a fungus was found in the sand dunes near IJmuiden which was new for the Netherlands.
It belonged to the Leucopaxillus genus, but it was difficult to find out which species. Very probably, it is Leucopaxillus paradoxus var. paradoxus, but more research is still needed.
