Contents
Leccinum is a genus of fungi in the family Boletaceae. It was the name given first to a series of fungi within the genus Boletus, then erected as a new genus last century. Their main distinguishing feature is the small, rigid projections (scabers) that give a rough texture to their stalks. The genus name was coined from the Italian Leccino, for a type of rough-stemmed bolete. The genus has a widespread distribution, especially in north temperate regions, and contains about 75 species.
Ecology and habitat
Dark-Stalked Boletes fruit on the ground in mixed woods.
"Leccinum species are generally found in the woodlands of Europe, Asia, and North America, forming ectomycorrhizal associations with trees. Most Leccinum species are mycorrhizal specialists, associating with trees of a single genus. Leccinum aurantiacum is an exception, however, occurring in mycorrhizal association with poplar, birch, and oak.
As food
Leccinum atrostipitatum is edible and enjoyable, but do your homework and eat at your own risk.
"Leccinum" species in general have been presumed to be edible for the most part, but there are reports of poisoning after eating as yet unidentified members of the genus in North America, even after thorough cooking. The orange- to red-capped species, including L. insigne, are suspected. Species of Leccinum often cause nausea when consumed raw.
Cooking
The key is preparation. A dry-saute is best. Clean and slice the mushrooms, then put them in a skillet on maximum heat with no butter or oil. sprinkle them with salt (to help draw out the moisture). Stir constantly until they begin to give off liquid, then let them cook in their own juices. After the liquid has evaporated (you can pour off some of it for use as stock), continue to cook them for a couple of minutes, stirring constantly again so they don't stick. Then turn down the heat, add a little olive oil or butter, and cook for another 5–10 minutes. They should be fairly chewy and full of flavor, not slimy, You can eat them as they are or incorporate them into any dish.
