Lactarius pallescens, commonly known as the pallid purple-staining milk cap, [1] is a Western North American "milk-cap" mushroom, of which the milk turns violet when the flesh is damaged. The fungi generally identified as L. pallescens are part of a complex of closely related species and varieties which have a peppery taste and are difficult to delimit definitively. [2]

Contents

The gray-brown cap ranges from 3 to 10 cm in width, with a mucilaginous surface, [3] whitish flesh and white latex. The gills are whitish and sometimes slightly decurrent. [3] The viscid stalk ranges from 3 to 8 cm long and 1 to 2 cm wide. The spores are pale yellow to orange, elliptical, and bumpy. The flesh of the mushroom stains lilac. [4] In age, reddish stains develop. [3]

Distribution

Lactarius pallescens is found on the West Coast of the United States. In the Pacific Northwest, it can be found in conifer forests. [3]

Lactarius uvidus (a close relative) [4] [3] and Lactarius californiensis are similar.
