Lactarius aestivus, commonly known as the orange fir milk cap[1] or summer saffron milkcap,[2] is a species of mushroom in the family Russulaceae.

Description

The cap of Lactarius aestivus is orange to pale orange in color and about 3-12 centimeters in diameter. It starts out convex with an inrolled margin and becomes depressed as the mushroom matures. The gills are orange to orangish buff in color and adnate to subdecurrent. The stipe is about 3-6 centimeters long and 1-2.5 centimeters wide. It is orangish with brighter orange spots. The spore print is pale yellowish or cream-colored.[1] When cut, this mushroom sometimes produces small amounts of orange latex that stains greenish.[2]
