The maximum likelihood (ML) tree based on combined LSU, ITS, SSU, tef1-α, and rpb2 sequence data. Bootstrap support values with an ML greater than 75% and Bayesian posterior probabilities (PP) greater than 0.95 are given above the nodes, shown as “ML/PP”. The tree is rooted with Occultibambusa bambusae (MFLUCC 13–0855) and Neooccultibusa thailandensis (MFLUCC 16–0274). New species and collections are indicated in red; while the type strains are in bold black.
