Phylogeny of selected sequences of Hohenbuehelia based on a Maximum Likelihood analysis of three nuclear gene regions (nrITS, nrLSU, tef1). The Maximum Likelihood bootstrap values (BS ≥ 70%) and Bayesian posterior probabilities values (PP ≥ 0.90) are shown on the branches. Newly-sequenced collections are in bold. Five Pleurotus species were used as outgroup. (T) designates holotypes. The sequence H. flabelliformis voucher number MFLU22-0008 was identical to MFLU22-0009 (ITS only). Sequences of H. lageniformis voucher number MFLU22-0010 were identical to MFLU22-0012 (ITS and LSU). Sequences of H. tristis voucher number MFLU22-0016 were identical to MFLU22-0015 (ITS and LSU) and to the two specimens MFLUCC 12-0451 and HFJAU0029, identified as H. grisea (both only ITS) from GenBank, except for three substitution heteromorphisms in the ITS sequence of MFLU22-0016 (see Table 2).
