Actinomycetes are microorganisms that are a sort of transitional group between bacteria and fungi.
Like fungi, they produce tendril-like hyphae. But they also have cell walls, like bacteria. Actinomycetes are intriguing characters. They are able to decompose some fairly complex organic compounds. They eat tough substances such as cellulose and chitin.
