Digitodesmium tectonae (Rajeshkumar, R. K. Verma, Boonmee, K. D. Hyde, Chandrasiri & Wijayaw.) W. H. Tian & Maharachch , comb. nov.

MycoBank: MB 844526

Basionym: Paradictyocheirospora tectonae Rajeshkumar, R. K. Verma, Boonmee, K. D. Hyde, Chandrasiri & Wijayaw, Phytotaxa 509 (3): 259–271 (2021).

Notes: The genus Paradictyocheirospora was introduced by Rajeshkumar et al. (2021), with P. tectonae as the type species. The phylogenetic analysis based on a combined dataset of LSU, ITS, SSU and tef1 sequences show that P. tectonae is clustered within Digitodesmium ( FIG. 1 ). In addition, Paradictyocheirospora possesses key characteristics of Digitodesmium such as punctiform, sporodochial conidiomata, acrogenous, cheiroid, digitate conidia, with an apical gelatinous cap ( Kirk 1981; Rajeshkumar et al. 2021; Nóbrega et al. 2021). Thus, Paradictyocheirospora and Digitodesmium are congeneric. Digitodesmium is the older name and should take priority, and this selection is recommended here.

FIGURE 1. Phylogram of the best ML tree based on a combined dataset (LSU, ITS, SSU and tef1) of Dictyosporiaceae. The ML ultrafast bootstrap values/Bayesian PP greater than 75%/0.95 are indicated at the respective nodes. Type isolates are in bold, and the new taxa and synonymized taxa are indicated in red. The tree is rooted with Periconia igniaria (CBS 845.96).
