Leptodictyum riparium, commonly known as Kneiff's feathermoss,[1] streamside leptodictyum moss,[2] or knapwort,[3] is a species of moss[4] of cosmopolitan distribution. The only places it is not found are the Pacific Islands and Australia.[3] It is commonly found growing in the lakes and rivers of Minnesota[5] and is also present in Mexico, Guatemala, the Bahamas, Cuba, Jamaica, Haiti, the Dominican Republic, Venezuela, Peru and Brazil.[6]

This moss has several different forms and can grow up to 30 cm. Its ovate leaves, which are in two rows, are often pointed at their apex.[3] Leptodictyum riparium has been found in an acidic mining lake and can live at a pH down to 1.6 in volcanic craters. It was once found with Eleocharis acicularis at a Canadian mining lake.[7] It is known to contain high levels of phosphate[8] and is an easy to grow moss that is also used in aquariums. It has been reported that L. riparium tolerates a wide range of nutrient conditions and its population increases as ammonia increases.[9]

Leptodictyum riparium is known to be able to use artificial light to grow in places which are otherwise devoid of natural light, such as Crystal Cave in Wisconsin.[10]
