Abstract
Abstract. Phaeocalicium atenitikon is described new to science, growing on twigs of Juglans nigra (black walnut) in central North America. The species is characterized by small ascomata; an exciple of brown, periclinally arranged hyphae; notably small, pigmented, two-celled ascospores with pale septa; and its substrate and distribution. These are the first records of a corticolous Phaeocalicium from intermountain North America south of the Great Lakes region. Differences among similar species are discussed, and a worldwide key is provided for members of the genus with persistently 1-septate ascospores.
期刊介绍：
The Bryologist is an international journal devoted to all aspects of bryology and lichenology, and we welcome reviews, research papers and short communications from all members of American Bryological and Lichenological Society (ABLS). We also publish lists of current literature, book reviews and news items about members and event. All back issues of the journal are maintained electronically. The first issue of The Bryologist was published in 1898, with the formation of the Society.
Author instructions are available from the journal website and the manuscript submission site, each of which is listed at the ABLS.org website.
All submissions to the journal are subject to at least two peer reviews, and both the reviews and the identities of reviewers are treated confidentially. Reviewers are asked to acknowledge possible conflicts of interest and to provide strictly objective assessments of the suitability and scholarly merit of the submissions under review.
