Taxonomic notes


Why suggested for a Global Red List Assessment?


Geographic range

Suillus granulatus is fairly common to common in Europe¸ Asia and North America. Introduced to South Africa, South America, Australia, New Zealand, Hawaii, Chile.Suillus granulatus is the most widespread pine-associating Suillus species in warm climate. 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.
