We describe three new fungicolous species on the basis of phenotypic and phylogenetic differences from known species. Penicillium thiersii, P. angulareand Penicillium decaturenseare described. Penicillium thiersiiphenotypically is identified on the basis of several characteristics including growth rates, vesicle size and condium shape and roughening. Penicillium angulareis related most closely to P. adametzioidesbut differs from it by restricted growth rates and conidiophores greater than 60 μm in length. Penicillium decaturenseis related most closely to P. miczynskiibut differs from that species by growth rate, minimum growth temperature and pigment production on MEA. Multilocus phylogenetic analysis confirmed the genetic distinctiveness of P. decaturenseand the closely related species P. miczynskii, P. chrzaszcziiand P. manginii. Penicillium rivoliiis a synonym of P. waksmaniion the basis of this analysis. Analysis of the EF-1α gene shows rapid changes of position, number and length of introns between the species, suggesting a recent evolutionary origin for the introns. |
