The powder consists of the dry spores of clubmoss plants, or various fern relatives principally in the genera Lycopodium and Diphasiastrum.The preferred source species are Lycopodium clavatum (stag's horn clubmoss) and Diphasiastrum digitatum (common groundcedar), because these widespread and often locally abundant species are both prolific in their spore production and easy to collect.

Lycopodiopsida is a class of vascular plants also known as lycopsids, [1] lycopods, or lycophytes. Members of the class are also called clubmosses , firmosses , spikemosses and quillworts . They have dichotomously branching stems bearing simple leaves called microphylls and reproduce by means of spores borne in sporangia on the sides of the ...
The spores of Lycopodium species are harvested and are sold as lycopodium powder. Lycopodium sp. herb has been used in the traditional Austrian medicine internally as tea or externally as compresses for treatment of disorders of the locomotor system, skin, liver and bile, kidneys and urinary tract, infections, rheumatism, and gout, [ 12 ...
Spores are also highly flammable due to their high content of oil. They have been used culturally for ceremonial purposes when medicine men tossed the spores into a fire for a flash of light. The spores ignite with a bright flash of light and were used in flash photography, in stage productions, in fireworks and in chemistry labs. [9]
D. obscurum reproduces sexually via spores and also vegetatively, through its rhizome. [10] The gametophyte of D. obscurum is disc shaped prothallus, [11] measuring an average of 1.5 cm (0.6 inches) in diameter. [12] It closely resembles other gametophytes of Lycopodium and related genera, so it cannot be identified by gametophyte alone.
Like all lycophytes, members of the Lycopodioideae reproduce by spores. The oldest fossils of modern members of the subfamily date to the Early Cretaceous. [3]
Spinulum annotinum, synonym Lycopodium annotinum, known as interrupted club-moss, [1] or stiff clubmoss, [2] is a species of clubmoss native to forests of the colder parts of North America (Greenland, St. Pierre & Miquelon, all 10 provinces and all 3 territories of Canada, Alaska, and mountains of the contiguous United States), [3] as well as Asia (China, Russia, Japan, Korea, Nepal, Assam ...
