Lactarius scoticus Mushroom Identification
Is initially convex before developing a central depression, sometimes becoming funnel-shaped, and reaches diameters of 1.4–6 cm (0.6–2.4 in). The cap surface is smooth overall and dry, but sometimes has small cracks in the center, and an increasingly felt-like texture moving towards the margin, which is usually fringed with 1–2-mm long hairs. The color is initially pale cream to whitish, later becoming pale pinkish-buff to cream, with a more yellowish to yellowish-brown center.
The crowded gills have an adnate to decurrent attachment to the stem. Whitish to pale pinkish-buff in color, they are sometimes forked near the stem attachment.
The stem measures 2.0–7.5 cm (0.8–3.0 in) long by 0.4–1 cm (0.2–0.4 in) in diameter, and is either cylindrical to slightly club-shaped. It has a smooth to finely felty surface with a light cream to pinkish-buff color.
The flesh is similar in color to the outer surfaces; it has an acrid taste and an acidic to fruity odor. The sparse latex is white and has an immediately acrid taste.
The spores are ellipsoid in shape, measuring on average 6.5–6.9 by 4.9–5.0 µm. The spore surface features warts and ridges up to 0.5 µm high that are connected by thin ridges to form an incomplete reticulum. The basidia (spore-bearing cells) are cylindrical to club-shaped, four-spored, and measure 30–45 by 7–9 µm.
