| Abstract: | Paecilomyces nostocoides, in which conidia of smaller or larger sizes appear in chains, was newly isolated from Japan. In addition to the typicalPaecilomyces-type conidiation, the Japanese isolate showed additionalAcremonium-like submerged conidiation in and/or on some agar media. The submerged conidiation was also observed in the ex-type strains, but not in the type specimens ofP. nostocoides. The same submerged conidiation was observed inP. lilacinus, the species most similar toP. nostocoides. The species definitions ofP. nostocoides andP. lilacinus were emended to include the submerged conidiation.Paecilomyces-type conidia were uninucleate in bothP. nostocoides andP. lilacinus. Paecilomyces nostocoides andP. lilacinus had the Q-10(H2) ubiquinone system. |
