Basidiospores 8.5-10.8 X 6.6-7.6 μm – D/d = 1.23-1.43 (13-08-12/07); 8.7-9.9 X 6.6-7.5 μm, D/d = 1.23-1.37 (16-09-19/09). Stipitipellis an ixocutis. Cheilocystidia not seen. Pleurocystidia similar to narrow lactiferous hyphae, tortuous.

Lactarius thyinos is similar to Lactarius deterrimus but differs in not developing green colours in cap and stipe, in having an outer gelatinous layer on the stipe (an ixocutis) and in its longer, narrower basidiospores.
