Plagiomnium cuspidatum, also known as toothed or “baby-tooth” plagiomnium moss and woodsy thyme-moss, is a species of thyme-moss that originated in North America, but can now also be found throughout Middle America, Africa, Northern and Southern Asia (excluding China), and Europe.

Moss leaf under microscope, showing gemmae and a hair point (40x) Moss gametophytes have stems which may be simple or branched and upright (acrocarp) or prostrate (pleurocarp). The early divergent classes Takakiopsida, Sphagnopsida, Andreaeopsida and Andreaeobryopsida either lack stomata or have pseudostomata that do not form pores.
The International Moss Stock Center (IMSC) is a biorepository which is specialized in collecting, preserving and distributing moss plants of a high value of scientific research. The IMSC is located at the Faculty of Biology , Department of Plant Biotechnology, at the Albert-Ludwigs-University of Freiburg , Germany.
