New or Noteworthy Penicillia from Wisconsin Soils

SUMMARY

Two new species of Penicillium are described: P. pinetorum, assigned to the P. thomii Series and found to be relatively common in soils of Wisconsin forests dominated by red pine, white pine, or both; and P. odoratum, an aromatic monoverticillate form probably related to P. trzebinskianum Abe, which was found to be abundant in bog soils in communities of Chamaedaphne-Ledum-Kalmia and Picea-Larix in northern Wisconsin. Descriptions are also given for three mold entities, identified respectively as Penicillium canadense Smith, P. daleae Zaleski, and P. radulatum Smith, which were isolated from soils in coniferous areas of Wisconsin, in some cases in considerable abundance, but which seem not to have been previously recorded from the United States.
