In an ongoing survey of Penicillium species occurring in China, 465 strains were isolated from soil, and of which 60 belonged to section Lanata-divaricata. The majority of these strains were isolated from acidic soil. The phylogenetic relationship between these 60 isolates and accepted species of section Lanata-divaricata was studied using ITS, BenA, CaM and RPB2 sequences, which revealed the presence of seven accepted species and 13 novel lineages. Combining phylogenetic data with data generated during macro- and microscopic observations resulted in the description of 13 new species. The growth rate of the new species obtained in this study was determined under acidic, neutral and alkaline conditions (pH 4, 7, 10). With the exception of P. hainanense, which was not able to grow at pH 10, all strains were able to grow at the three examined pH levels. Eleven species (i.e. P. austrosinense, P. flaviroseum, P. globosum, P. griseoflavum, P. hainanense, P. jianfenglingense, P. laevigatum, P. rubriannulatum, P. soliforme, P. spinuliferum, P. yunnanense) grew faster at low pH (pH 4) than at pH 7 or 10, and these species are therefore referred to as acidpreferential. Penicillium viridissimum grew fastest on neutral medium and P. guangxiense grew best at pH 10, and is therefore considered to be acid-tolerant. By isolating strains from a unique environment, combined with targeted isolation using a well-designed protocol, we are able to describe new fungal diversity with specific physiological characteristics.} }
