That’s why we can all be excited about a forthcoming book, Milk Mushrooms of North America: A Field Identification Guide to the Genus Lactarius by A.E. A few other milky caps are distinctive, such as the lovely Lactarius indigo (yep, it’s blue), but often Lactarius species are tough to identify. There are very many Lactarius species–Hesler and Smith treated over 200 in North America. ![]() Benjamin says is “ill-advised”).Įditor’s Note: Despite its drab colors, Lactarius helvus is one of the milky caps that ordinary muggles like me can identify–because of its odor. In northern Europe this mushroom is sometimes dried and used in small quantities as a spice (a practice which wise Dr. It appears to become inactive upon boiling (or perhaps it is leached out).

The distinct smell of Lactarius helvus comes from a cyclic ester called sotolon (or 3-hydroxy-4,5-dimethyl-2(5H)-furanone, if you must know). helvus for now, but should our North American species turn out to be different from its European cousin, L. Michael Kuo has provided a fine explication of this name confusion. In 1979 Hesler and Smith began calling this mushroom Lactarius aquifluus Peck, instead of using the older name Lactarius helvus.

Although this odor is sometimes weak in young specimens it becomes more pungent upon drying. The whole mushroom has a distinct scent reminiscent of curry or maple syrup. This milky cap releases a watery and colorless latex that does not stain the flesh of the mushroom. It has some easily identifiable characteristics.
