stromata are rounded balls, 1 - 6 cm, single or in clumps; when fresh bright yellow outside with gelatinous wall, hollow with liquid inside. Color duller and darker when older or dried, and then collapsing. Perithecia (spore producing chambers) are sparse or sometimes absent.
Puffballs are solid or have powdery spores on the inside.
Daldinia are dark brown to black on outside, occasionally with liquid insides, otherwise solid with zones lines.
Saprobe on dead hardwoods. In the USA, habitats include floodplain woods and terrace forest.
Spring, summer, fall; also winter in tropics.
Widespread in southeastern North America (southern states and in Mexico on the Yucatán Peninsula) to Brazil and Argentina; Africa and Asia. Rarely found or collected. For the USA there are only 19 collections on MyCoPortal plus 24 photo observations on Mushroom Observer and iNaturalist.
Found at Cahokia Mounds State Park, St. Clair County (near St. Louis) by the Missouri Mycological Society, August 31, 2005. We found it at the Dixon Waterfowl Refuge Bioblitz, Putnam County, August 5, 2018; this is north-central Illinois and fills a gap in the Upper Midwest distribution.
