The North American Slime-Moulds A Descriptive List of All Species of Myxomycetes Hitherto Reported from the Continent of North America, with Notes on Some Extra-Limital Species

This volume offers a systematic guide to the slime‑moulds, or Myxomycetes, recorded across North America. Drawing on specimens housed in the State University of Iowa’s herbarium and contributions from botanists as far north as Alaska to the tropical reaches of Panama, it presents concise, reliable descriptions for each species known up to the early twentieth century. The author’s aim is to provide a practical reference for students, field naturalists, and anyone curious about these organisms. It also includes occasional notes on related species found outside the continent, highlighting broader distribution patterns.

Entries are organized, each paired with detailed observations of morphology, habitat, and geographic range, and many are accompanied by drawn plates that reveal the delicate structures of sporangia and plasmodia. The introductory sections explain the challenges of slime‑mould nomenclature and trace the development of American mycological study, giving listeners a sense of the scientific context in which the work arose. Though rooted in the scholarship of its era, the book remains a valuable starting point for anyone wishing to identify or simply appreciate the diversity of North American slime‑moulds.
