Junghuhnia chlamydospora is a species of poroid crust fungus in the family Steccherinaceae.

The type specimen was collected in the Cockscomb Basin Wildlife Sanctuary in Belize, growing on a dead standing tree.

The crust-like fruit bodies of the fungus measure up to 2 millimetres (0.079 in) thick and have an ochraceous margin.

It has finely encrusted skeletal hyphae, similar to the related Saint Lucian fungus J. carneola.

The abundant chlamydospores, for which J. chlamydospora is named, measure 8–12 by 4–6 μm and are strongly dextrinoid.
