Abstract
Two species of Aleurodiscus occurring on conifers, which have been under observation for several years, are described as new. Both are related to Aleurodiscus roseus (Pers. ex Fr.) Höhn. & Litsch. The first, described as A. Minnsiae sp. nov., occurs most commonly on Tsuga canadensis and is noteworthy because of an associated sclerotial disseminating phase of characteristic morphology, which has been known under the herbarium name Minnsia carnea E. & E. ined. The history of our knowledge of this phase is given in some detail. The second species occurs on Pinus Strobus and is described as A. Pini sp. nov. The known collections of both species are listed. Comparative culture work was conducted which showed that the two species are heterothallic, have a different growth rate, and are incompatible. They are also different from a form of A. roseus occurring on Populus which proved to be homothallic.
