Tells: Brown-on-white scaber stem. White pores age to yellow-brown & DNS. White cap flesh stains purple-gray & resolves black – no red stage. Likes aspen & birch.
Other Information: Rusty-orange to cinnamon-brown cap. This is a “placeholder” name for all birch/aspen-loving, red- or orange-capped Leccinums.

Science Notes: See this Article on the Red-Cap Leccinum Taxonomy Mess. At least insigne is a North American name! The problem is that the name most likely includes several different species, and knowing exactly which one you’ve got will be impossible until enough DNA evidence gets compiled to tell what those species are. Who know? Maybe it really is just one, very variable species after all…
Edibility: Good.
CHEMICAL TESTS:
- NH4OH (Ammonia): Cap surface has no reaction. Cap flesh has no reaction.
- KOH: Cap surface turns grayish. Cap flesh turns grayish.
- FeSO4 (Iron Salts): Cap surface has no reaction. Cap flesh turns bluish.
