The Erpodiaceae (Bryophyta) is a family of very small to small, pleurocarpous mosses most closely related to the Orthotrichaceae. Mosses in the Erpodiaceae are found mainly in drier areas of the tropical and subtropical regions of the world. Five genera are recognized in this study—Aulacopilum (2 species, 3 subspecies), Erpodium (2 species), Solmsiella (2 species), Tricherpodium (1 species, 2 subspecies), and Venturiella (8 species, 7 subspecies). This study is primarily morphologically based. The genera and species within each genus are arranged alphabetically. Keys are provided to the genera, sections, species, and subspecies. All genera, sections, species, and subspecies are described; illustrations and distribution maps are provided for each species and subspecies. The book includes twenty nomenclatural novelties.
Ronald A. Pursell (1930 – 2014) was for more than three decades a Professor of Botany at The Pennsylvania State University, and was a prodigious bryophyte scholar. A written, but unpublished, manuscript at the time of his death was a taxonomic revision of the Erpodiaceae. Pursell’s former graduate student and colleague Bruce Allen read the completed draft of the manuscript, edited it, and saw the project through to the present publication. Allen also drew the pencil habit sketches of the species and subspecies.
Bruce Hampton Allen was born in Wilmington, Delaware and grew up in and around Philadelphia, Pennsylvania. He attended Pennsylvania State University on an athletic scholarship, where he played soccer, was a long-jumper on the track team, and graduated with a B.S. degree (biology) in 1974. He began studying mosses at Penn State in 1976. He earned an M.S.degree (Botany) there in 1980 and a Ph.D. degree (Biology) in 1985 from theUniversity of Cincinnati. From 1984 until 1986, he was a Jesse Smith Noyes postdoctoral fellow at The Missouri Botanical Garden, and since 1987, he has been a curator there. He is the author of five books and 296 papers on mosses and currently is working on the fourth (and final) part of the Moss Flora of Central America. His primary research interest is floristics, and he is currently working on part three of the Moss Flora of Central America. while continuing to pursue revisionary studies on a wide range of moss groups. His interest in Maine can be attributed to his paternal grandparents.

He has been a nearly lifelong summer resident of Boothbay Harbor, Maine. Bruce Allen's Author Page

Following graduation from high school in 1948, he matriculated at The Pennsylvania State University, University Park. majoring in Botany and was awarded a B.S. (1952) and an M.S.(1954). His Ph.D. in Botany was awarded in 1957 by Florida State University, Tallahassee. During his formative years in Florida. he gained two life-long friends and colleagues. Paul L. Redfearn and William D. Reese. His first two academic appointments were at University of Colorado, Boulder (1957-1958) and University of Tennessee, Knoxville (1958-1959). In 1959 he returned to The Pennsylvania State University, rising through the academic ranks, Instructor (1959-1963). Assistant Professor (1963-1968), Associate Professor (1968 -1977). and Professor (1977-1991). He retired from formal academic activities in December 1991. He served The American Bryological and Lichenological Society as: Director of the Moss Exchange (1960-1974): Vice-President (1973-1975): and, President (1975-1977). During his tenure with The Pennsylvania State University, he was major professor for Bruce Allen (M.S.1978). Robert E. Hattaway (Ph. D., 1973). Shan-busing Lin (Ph. D.. 1982), Monte G. Manuel (Ph.D.. 1976), Eric Randall (Ph.D.. 1973). and Lloyd Stark (Ph.D.. 1985). In December 1988 he was invited by the University of Utrecht, the Netherlands to be an examiner for the Ph.D. of Maria Alida Bruggeman-Nannenga. In 1988 he was appointed as a Research Associate of the Missouri Botanical Garden, St. Louis. He has collected bryophytes in many areasof North America and has participated in bryological collecting trips to Mexico, Puerto Rico, Brazil, Suriname, the Canary Islands, and The Netherlands. His research interests are primarily the Fissidentaceae, but also the Bryoxiphiaceae, Erpodiaceae, Eustichiaceae, Phyllodrepanaceae, Phyllogoniaceae, Splachnobr Ronald A. Pursell's Author Page
