Welcome to North American Fungi

North American Fungi publishes original, peer-reviewed articles on Fungi (Chytrids, Zygomycetes, lichenized and non-lichenized Ascomycetes, and Basidiomycetes) as well as other organisms traditionally studied by mycologists, such as Oomycetes and slime molds. Manuscripts are published by posting them to this website following rigorous peer review. In order to expedite publication, postings occur as soon as manuscripts are ready for publication rather than at set intervals.

Podosphaera fusca
A widespread powdery mildew producing conidia with fibrosin bodies

Podosphaera fusca is a common powdery mildew that parasitizes a wide range of economically plant species. As in other species of Podosphaera, Cystotheca and Sawadaea, it forms conidia with fibrosin bodies. These inclusions can be rod-shaped, rhomboidal, donut-shaped, funnel-shaped, or reminiscent of commas or parentheses. Although known for many years, scientists still know little about how fibrosin bodies form, what comprises them, or what function they play in the biology of these fungi. Nonetheless, they have been shown to be useful in determining powdery mildew genera and species.
