Composed of, or containing chitin, a long chained structural polysaccharide. Found in the exoskeleton of arthropods.
The Phylum Chitinous is further organized into finer groupings including:
- Class (1): Ascomycetes
- Species: ZipcodeZoo has pages for 2 species, subspecies, varieties, forms, and cultivars in the Phylum Chitinous.
The Ascomycota are a Division/Phylum of the kingdom Fungi, and subkingdom Dikarya. Its members are commonly known as the Sac fungi. They are the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the "ascus" (from Greek: ?s??? (askos), meaning "sac" or "wineskin"), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomycetes are now identified and classified based on morphological or physiological similarities to ascus-bearing taxa, and by phylogenetic analyses of DNA sequences.

At least 25,205 species and subspecies belong to the Class Ascomycetes.
