Just like other biotopes, pine forests have their own specific mushrooms, some of which grow exclusively in coniferous forests. Most dune woods in the Netherlands have an unnatural origin. They were planted around 100 years ago, primarily with coniferous trees. Many nature-lovers find the monotonous pine growth in the dunes boring. The number of unusual plants and exceptional animal life is low. However, it is ideal terrain for mushrooms. In the meantime, many of the pine woods are now mixed with deciduous trees, increasing the spectrum of mushroom species. A few characteristic species for dune woods are the velvet bolete, the gemmed amanita and, the most poisonous mushroom found in the Netherlands, the deathcap.
