Index Fungorum number: 223913
When fully grown, the medium to large sporocarps of L. hatsudake extend 3–10 cm in diameter, they’re broadly spherical when young and later become funnel-shaped. The striking characteristics are pale reddish to dirty brownish pink buff with more or less concentric zonation. The cap becomes slightly translucent when wet and opaque when dry; the gill colour is a pale red when young, a pale to vinaceous red when mature and becoming ochraceous mixed with a green or bluish green when aged. The stalk is dull red and quite firm. The cap is the same colour and the species has hollow pith. This species exudes vinaceous red when injured, milk unchanging when exposed to the air, and flesh staining vinaceous red after cutting. The smell is sweetish, and the taste is mild. This species should not be confused in the field as it possesses some remarkable characteristicss i.e. milk and gill colour.
