Other similar mycenas that grow in clusters on wood include M. maculata and M. galericulata.
The fruit bodies of M. maculata often develop red stains as they mature, but this characteristic is inconsistent and cannot be reliably used for identification.
Its spores are larger than that of M. overholtsii, measuring 7–10 by 4–6 μm.
M. galericulata is very similar in appearance to M. maculata, but does not undergo reddish staining; its spores are 8–12 by 5.5–9 μm.
Another similar species is M. semivestipes, which can be distinguished by its bleach-like odor, an eastern North American distribution, fruiting season during summer and autumn, and small spores measuring 4–5 by 2.5–3 μm.
