Lactarius psammicola: The Ultimate Mushroom Guide
About The Lactarius psammicola Mushroom
Lactarius psammicola has a cream-yellow to a cream-orange color cap, and measures from 4 to 16 cm. The mushroom's insides are white and fleshy, and produce a white latex when cut. Its mushroom cap is convex when young and becomes funnel-shaped as it ages. The cap has concentric rings of orangish brown.
The mess surrounding the North American versions of the European species Lactarius zonarius gets my vote for All-Time Worst Lactarius Nightmare. We have, on our continent, a bunch of poorly understood and often poorly defined species, varieties, and forms that are similar to Lactarius zonarius. Among these, Lactarius psammicola is arguably the most clearly delineated and recognizable species.
Lactarius psammicola habitat from Michigan to Central America and is primarily found associated with oaks during the summer.
