Zhu L.Yang, G.M.Muell., G.Kost & Rexer (2009) Xerula megalospora is a species of gilled mushroom in the family Physalacriaceae.

Xerula megalospora fruit bodies occur on the ground, solitarily or in small groups.

They are saprobic and found near the well-decayed stumps of oak or other broadleaf trees.

The caps, 2–10 cm (0.8–3.9 in) across, can be a convex or umbonate shape eventually becoming flat and centrally depressed.

The flesh of Xerula megalospora is white, and the odor is sometimes described as being reminiscent of carrots.
