Yellow Moosedung Moss (Splachnum luteum)

The Yellow Moosedung Moss, scientifically known as Splachnum luteum, is a fascinating moss with a rather unique habitat preference. Its common name directly reflects its tendency to grow on the dung of ungulates, particularly moose.

Taxonomy and Nomenclature

• Scientific Name: Splachnum luteum
• Common Name: Yellow Moosedung Moss
• Family: Splachnaceae
• Group: Moss
• Division: Bryophyta
• Symbol: SPLU7
• Synonyms: Mentions Splachnum rubrum, though it's not explicitly stated as a synonym, it is presented in similar context.

Distribution and Habitat

This moss is often found in areas where moose are prevalent, such as bogs and fens, and its presence is closely linked to the availability of herbivore dung. One documented location is Ranua, Finland.

Ecological Role

• The Yellow Moosedung Moss relies on insects to spread its spores. These insects visit the herbivore dung where the moss grows, facilitating spore dispersal.

Morphological Characteristics

• The Yellow Moosedung Moss is noted for its showy sporophytes, described as one of the most beautiful moss sporophytes. Its yellow discs are conspicuous among rust-colored lines.
• It is a nonvascular plant with a nonvascular growth habit.

Interactions with Other Organisms

• Splachnum luteum has a symbiotic relationship with insects, which aid in spore dispersal.
• It grows on the dung of herbivores, especially moose. Occasionally it grows on regurgitated owl remains.

Quirky Facts

• The Yellow Moosedung Moss inspired the design of a pattern for a set of products expressing belongingness in Norrbotten. It is also Norrbotten's provincial moss.
• Some observers initially mistake it for a fungus or mushroom due to its appearance.
