Abstract

Penicillium simplicissimum is a broadly described taxon often encountered on soil community lists and in biotechnological reports. Phylogenetic analysis of the ITS1-5.8S-ITS2 rDNA region indicated that P. simplicissimum s.l. includes several species. Recognition of these species is further supported by differences in micromorphological characters, particularly of the conidia and phialides, and the production of distinct profiles of secondary metabolites by each species. Group-I introns were identified in six of the 21 isolates; their presence was used to test hypotheses about the monophyly of the P. pulvillorum and the other intron-bearing strains. Our results show that P. brasilianum, P. ochrochloron, P. piscarium, P. pulvillorum and P. simplicissimum should be recognized as distinct and valid species. Three additional, undescribed species were identified within the P. simplicissimum group, here referred to as Penicillium spp. I, II and III. The name P. simplicissimum should be used only for isolates which match the neotype and NRRL 902 in all characters.
