Phylogenetic tree of Penicillium sect. Exilicaulis species ex-type strains using the ITS region. Penicillium toxicarium (CBS 351.51) was chosen as outgroup. Posterior probabilities (pp) and/or bootstrap values (bs) higher than 0.95 and 80 respectively, are given above thickened branches. Names in bold indicate fynbos strains, names in blue indicate new species strains, T = ex-type strain.
