The fruit bodies of Colospora species are crust-like with tiny spines. The hyphal system is dimitic (containing both generative and skeletal hyphae), and there are clamp connections present in the generative hyphae. Short-branched dendrohyphidia are common in the hymenium, and the apex of the spines are sterile. The spores are relatively large, thin walled, and biapiculate.
