Fungus
The cells of fungi have nuclei, unlike bacterial cells. Hyphae sometimes consist multiple nuclei. Their cell walls are  composed chitin, in contrast to the cellulose found in cell walls of plants. These and other differences show that fungi form a single group of related organisms. This group of fungi is referred to as the Eumycota or Eumycetes. They share a common ancestor, making them a monophyletic group.
