Triblidium verrucosum (O.E. Erikss.) T. Lv, C. L. Hou & P. R. Johnst. comb. nov.

≡ Huangshania verrucosa O.E. Erikss., Systema Ascomycetum 11: 2, 1992.

Notes.

The placement of this species in Triblidium is demonstrated by the phylogeny presented in Fig. 1 . Eriksson (1992) discussed the similarities between Huangshania and Triblidium in macro-morphology and in the morphology of hamathecial tissues and asci. The two genera differed only in ascospore morphology (elongate-phragmosporous vs. ellipsoidal-muriform). Karakehian et al. (2019) reviewed that ascospore morphology is a poor predictor of relatedness amongst these fungi. Huangshania verrucosa is the type species of the genus, therefore, Huangshania , is synonymized here under Triblidium .

Figures

Figure 1. A phylogenetic tree generated by maximum parsimony and Bayesian analysis of the combined ITS, LSU, mtSSU and RPB 2 sequences, using B. citrina and N. malicorticis as outgroups. Bootstrap values of maximum parsimony ≥ 70 % are shown above the respective branches. Bayesian posterior probabilities ≥ 0.95 are marked below the branches. Sequences in bold indicate that the sequences are from the holotypes.
