Abstract
We defined the regularities spatial distribution of Suillus aurihymenius based on the occurrence data, as well as bioclimatic characteristics in order to control species status in the natural environment. Suillus aurihymenius is a rare species known only from our collections from the Republic of Altai and Republic of Tuva. Realised niche of S. aurihymenius on the western border of its currently known range in larch forests in the floodplains of rivers of the steppe of southeast Altai. Conservation of natural habitats of S. aurihymenius in the steppes of intermontane basins in the southeast of Altai will contribute to its preservation in Russia.
Highlights
Suillus aurihymenius was first recorded by us in Russia, in the Altai Mountains in 2019 near Jazator [1]
We generated the frequency histograms based on bioclimatic variables BIO1 (Annual Mean Temperature) and BIO12 (Annual Precipitation) (Fig 3)
The histograms show the distribution of S. aurihymenius along the customized ranges for selected climatic variables
Summary
Suillus aurihymenius was first recorded by us in Russia, in the Altai Mountains in 2019 near Jazator [1]. Suillus aurihymenius is similar to S. tridentinus which is widespread in Europe, but differs from by its reddish gold hymenium color, stronger reddish brown discoloration of the context, and less squamulose pileus [2]
