- Epithet = very beautiful. Genus = named after Dutch mycologist Marinus Anton Donk (1908 - 1972).
- Annual. Brackets single or imbricate (overlapping). Upper surface matted hairy, somewhat resembling a Trametes. Underside with teeth. Kuo reports
pink to red reaction of the flesh to KOH.A helpful microscopic feature is the double or triple clamp connections on the hyphae; each septum (cross wall) can have no clamps or as many as four.
- Similar species:
- These lack the multiple clamps on hyphae. Hericium cirrhatum is more scaly on cap. Climacodon septentrionalis is typically in large overlapping clusters on maple. Spongipellis pachyodon has flattened teeth and angular pores.
- Saprobe causing white rot of dead hardwoods, rarely conifers.
- The few Chicago records are early August to middle September.
- Tropical and subtropical. Temperate distribution includes Japan; France, Spain, Russia. Widespread in eastern U.S.A, plus Arizona and at least one record in Canada. The New York Mycological Society has found it in New York City parks.
- Chicago Region status:
- Rare. Four records from two counties.
- U.S.A. South Carolina, H.W. Ravenel 1648 (no date) [at Kew].
- This species was also transfered to Steccherinum (1906) and Dryodon (1934). Moreno et al. (2007) questioned its placement in Climacodon because of the multiple clamps, apparent absence of cystidia, and preliminary molecular work. The species was not included in the molecular phylogeny of Binder et al. 2013. Moreno et al. (2017) confirmed its placement as Donkia in the Phanerochaetaceae.
- Specimens examined:
- Four specimens. Hyphal septa show 0 - 4 clamps.
