Phylogenetic analysis indicates that C. mucobrunneus is nested in sect. Defibulati and is more closely related to C. mucifluus and C. vanduzerensis (Fig. 1). Morphologically, C. mucobrunneus showcases a dark brown pileus with tile red to platinum blonde margins alongside a white stipe, in contrast to C. vanduzerensis has a chestnut-black pileus with chestnut-brown margins and a light purple to dark lavender stipe (Smith and Trappe 1972). Furthermore, C. mucobrunneus has larger basidiospores [13 –) 13.5–16 (– 17) × 8–10 (– 10.5) μm vs. (11 –) 12–14 (– 15) × 7–8 (– 9) μm] than C. vanduzerensis (Smith and Trappe 1972) . Cortinarius mucobrunneus is frequently misidentified as C. mucifluus due to the presence of translucent striations along the margin of the pileus, the pale stipe, and the cinnamon-hued annulus situated on the upper portion of the stipe. Nevertheless, C. mucobrunneus is characterized by a dark brown to liver brown pileus that exhibits broader basidiospores, in contrast to the ochraceous brown pileus of C. mucifluus, which features comparatively narrower basidiospores.</p></div>	https://treatment.plazi.org/id/15BEB6583D435BF2A0FEC479034C6A5C	Public Domain	No known copyright restrictions apply.
