Net-handled witch bolete ( Suillellus luridus )
The fruiting bodies are centrally stalked. The hat has a smooth or nearly smooth, dry or slightly smeary surface. The tubes are usually bare, small, and yellow. Their mouths, which are closed when they are young, are colored red or orange from the start. They are not covered by any velum. The stem is full and usually has a reticulated or dotted pattern. The firm flesh is white or yellow in color.
The elongated-elliptical and smooth-walled spores appear yellowish-brown and sometimes with green tones.
Suillellus species form ectomycorrhiza with various deciduous and coniferous trees.
The genus Suillellus comprises 11 species worldwide, 6 of which occur or are expected in Europe.

The genus Suillellus was established in 1909 by the American mycologist William Alphonso Murrill (1869–1957) with Suillellus luridus (originally described as a boletus species) as the type species. The taxon later disappeared in the synonymy of Boletus , but was taken up again by Alfredo Vizzini in 2014 after molecular studies showed that the species group around the net-handled witch boletus forms its own phylogenetic branch.
