STUDY OF THE MYCOBIOTA OF THE DUNE ECOSYSTEMS OF THE IBERIAN PENINSULA AND BALEARIC ISLANDS

Twenty-one taxa (10 Ascomycota and 11 Basidiomycota), collected in the dunes of Es Comú, Son Real and Es Trenc on the island of Mallorca, are studied and discussed. Three of them, Ciboria brunneorufa, Melanospora brevirostris and Inocybe pruinosa, are new records in the Balearic mycobiota, and two of them are new records for the island of Mallorca.

Mushrooms can be found in the forest. But also in the dunes by the sea.
Here you can find a fascinating pdf . In this scientific work you can see some new species, but also some already known species.
Most people do not look for mushrooms in the sea because they think that mushrooms only grow in the forest. But this is not true, we find mushrooms in the water, in and on fish and algae.
