Galanthus "Akrokorion"), he placed "Galanthus" in the family Liliaceae, section Narcissi. Lamarck provided a description of the genus in his encyclopedia (1786) and later "Illustrations des genres" (1793). In 1789 de Jussieu, who is credited with the modern concept of genera organised in families, placed "Galanthus" and related genera within a division of Monocotyledons, using a modified form of Linnaeus' sexual classification but with the respective topography of stamens to carpels rather than just their numbers. In doing so he restored the name "Galanthus" and retained their placement under Narcissi, this time as a family (known as "Ordo", at that time)
Chlamydomonas nivalis "Uredo nivalis". Over the next century, many researchers disputed over whether these organisms were lichen, plants, alga, or animal. It was not until the early 20th century when researchers finally began to agree on the algal nature of the organism and gave its currently known name, "Chlamydomonas nivalis". In 1968 "C. nivalis" was officially recognized as a collective taxon. Unfortunately, due to the lack of sequencing techniques, reliance on visually examining similarly looking snow alga, and complicated life cycle of this species, errors continued to be made in classifying this and other species of snow algae. Today, "C. nivalis" has
