Datroniella
Datroniella B.K. Cui, Hai J. Li & Y.C. Dai 2014, in Cui, et al., Fungal Diversity 97, 137–392 (2019)
Diagnosis: Basidiocarps annual, pileate to effused-reflexed, rarely resupinate. Pilei usually projecting less than 3 cm. Pileal surface brown to black, glabrous. Pore surface white, cream to pale brown; pores large to small, round to angular. Context pale brown to brown, corky. Hyphal system dimitic; generative hyphae bearing clamp connections; skeletal hyphae usually dominating, pale brown to brown, moderately to frequently branched in context and frequently branched in trama, IKI-, CB+; tissues darkening in KOH. Dendrohyphidia and cystidia absent, thin-walled cystidioles usually present. Basidiospores cylindrical, hyaline, thin-walled, smooth, IKI–, CB–.
Datroniella was newly set up by Li et al. (2014), species in this genus, previously, were included in Datronia. It is difficult to separate Datroniella from Datronia, the main differences are species in Datroniella having moderate to frequent branched skeletal hyphae and lacking dendrohyphidia. Phylogenetically, Datroniella is distinct from Datronia sensu stricto based on molecular sequences (Li et al. 2014)
