Description |
||
Aspen Bolete is a common and widespread mushroom. It is found on the ground, widely scattered or in groups, in woods and woodland edges under aspen and possibly also under birch. It obtains its nutrients from the rootlets of trees (mycorrhizal). It appears in the summer and early fall, August to October. The cap is hairless or minutely hairy, dry, and bright orange, reddish-orange, orangish-brown, or cinnamon. It is slightly slippery to the touch when wet. When young, in the button stage, it is round to convex and smooth, and there are usually flaps of sterile tissue attached to the margin. The cap spreads out as it ages. Mature caps are 2⅜″ to The stalk is firm, solid, somewhat tough and fibrous, and dry. It is 2⅜″ to The are no gills. There is a sponge-like layer of tubes on the underside of the cap. The tubes and tube openings (pores) are whitish or pale when young, becoming olive-buff to gray or yellowish-buff with age. They do not turn blue when bruised. The flesh is thick and often soft. It turns bluish-gray or purplish-gray when bruised or cut, but that may take a long time. Most sources state that all mushrooms in the genus Leccinum are safe to eat. Recently, however, Aspen Bolete has been known (or thought) to cause gastrointestinal distress in some individuals. The spore print is brown to yellowish-brown. |

Similar Species |

Orange-capped, scaber-stalked mushrooms in North America have often been identified as Red-Capped Scaber Stalk (Leccinum aurantiacum), even in printed guides and on popular mushroom Websites. However, recent DNA analysis suggests that Red-Capped Scaber Stalk is a European species that does not occur in North America. Those orange-capped misidentifications associated with broadleaved trees are most likely Aspen Bolete. |
