About Lactarius glyciosmus (Fr.) Fr.
Lactarius glyciosmus (Fr.) Fr. is a small to medium-sized agaric. Its cap is typically convex when young, measuring 2 to 6 centimetres (3⁄4 to 2+1⁄4 in) across, and develops a small central depression as it ages. A small central pimple is sometimes present. The cap is usually coloured greyish lilac, and may sometimes vary to pale buff. It is thin-fleshed, and younger specimens have an incurved cap margin. The stem grows 25 to 65 millimetres (1 to 2+1⁄2 in) tall, and is 4 to 12 millimetres (1⁄8 to 1⁄2 in) wide. It is cylindrical, most often widest at the base and narrower toward the top, though it may sometimes be club-shaped. The stem matches the cap in colour, but can be slightly paler or have a yellowish tint. It is notably soft, breaks easily, and may become hollow with age. The flesh is buff in colour. The gills are decurrent and crowded, starting pale yellowish to pale flesh-coloured and turning greyish lilac as they age. The mushroom produces white milk that has an initially mild taste, which becomes hot and acrid after a short time. It has a strong scent of coconuts. The spore print is creamy white. Individual spores are broadly elliptic, covered in small warts that are connected by thin ridges forming an incomplete network. Spores measure 7–9 by 5–6 micrometres. This common mushroom grows in soil under broad-leaved trees, particularly birch, and often grows among sphagnum moss. It fruits from late summer to autumn, growing either individually or in scattered groups. It has been recorded in North America, Europe, New Zealand, Svalbard, Japan, and China.
