My current scholarship interest is the distribution, diversity, and substrate relationships of fungi in Pennsylvania and surrounding states that utilize wood as a substrate. Wood is a unique habitat and the fungi utilizing it include parasitic species growing on living trees as well as saprophytes utilizing dead standing trees, fallen logs, and woody debris. Functioning as parasites or saprophytes, these fungi are integral components of forest ecosystems. Despite their importance, there is no available identification guide to the species of fungi utilizing wood as a substrate. Existing identification guides to fungi are either 1) obscure, 2) without keys, 3) very limited in species coverage, 4) national in scope, or 5) not restricted to species occurring on wood. I am developing a web-based, illustrated, dichotomous key to the common lignicolous fungi of this several state region. Opportunities exist for students to work with me on several aspects of the project.
