Penicillium section Charlesia was established based on a multigene phylogeny and includes a variety of species that can grow on diverse substrates. Three new species were identified in this section, highlighting the limited taxonomy research within the group. Through a multigene phylogenetic analysis, 12 distinct species were revealed, including three new ones, based on morphological characteristics such as macromorphology, vesicle width, and conidial shape.
Penicillium section Charlesia was established based on a multigene phylogeny of P. charlesii, P. coffeae, P. fellutanum, P. georgiense, P. indicum and P. phoeniceum. Since then, three additional species were described in the section. Species can occur on a wide range of substrata including soil, corn, coffee, water, air, deteriorating cloth and clinical samples. The majority of species in section Charlesia grow restricted on Czapek yeast extract agar and produce smooth-walled, vesiculate, monoverticillate conidiophores. A limited number of studies have reviewed the taxonomy of this section. In the present study, available strains belonging to section Charlesia were evaluated in a multilocus phylogenetic analysis using the ITS rDNA region, partial beta-tubulin (BenA), calmodulin (CaM) and RNA polymerase II second largest subunit (RPB2) sequences. This analysis revealed 12 distinct species, including three that are newly described here as Penicillium aspericonidium, P. fusiforme and P. longiconidiophorum. The macromorphology on different media, vesicle width, stipe length and ornamentation, and conidial shape and size are important morphological characters for distinguishing species of section Charlesia.
