Hypotrachyna subgen. Cetrariastrum (Sipman) Divakar, A. Crespo, Sipman, Elix & Lumbsch, comb. et stat.

nov. MycoBank No.: MB 803542

Cetrariastrum Sipman (1980: 335) . Type species:— Hypotrachyna ecuadoriensis (R. Sant.) Divakar et al. (2013: 21–38) ; Cetrariastrum ecuadoriense (R. Sant.) Sipman (1980: 343) . Parmelia ecuadoriensis Santesson (1942: 328) .

A subgenus in the genus Hypotrachyna , corresponding to clade 3 in Fig. 1 , including all species placed in Cetrariastrum by Sipman (1980, 1986) plus Everniastrum lipidiferum . The latter is included provisionally because it appears more distantly related to the other species.

FIGURE 1. 50% majority-rule consensus tree of the molecular phylogenetic relationships in the Hypotrachyna clade, based on 64000 trees from a B/MCMC tree-sampling procedure of a combined dataset of ITS, nu LSU, and mt SSU sequences. Two species of Parmeliopsis used as outgroup. Posterior probabilities ≥ 0.95 are given above the branches, and values below the branches are ML bootstrap values ≥ 70%. Branches that received strong support in any of the two analyses (RaxML and B/MCMC) are in boldface. Asterisk mark shows the type species of the genus Hypotrachyna. Clades numbered indicate phylogenetic clusters explained in the text.
