Kingdom Mycota consists of eukaryotic organisms. Fungi exist in two fundamental forms; multicellular, filamentous or hyphal form molds and unicellular or budding form yeast. Most of them are saprophytic and some are parasitic. They grow best in acidic environment tolerating acidic pH.

They can also tolerate high sugar concentration and dry condition. Molds are obligate aerobes and mycofa are facultative anaerobes.

Optimum temperature of growth for most saprophytic fungi is 0 C while 0 C for parasitic fungi. Fungi grow slowly as compared to bacteria. Cell wall is composed of chitin. Cell membrane consists of ergosterol. Both asexual and sexual mode of reproduction occur Asexual methods: More than 2,00, species of fungi are known, of which more than fungi are responsible for human infection.

Some fungi show mutualistic relationship with higher plants, eg. Mycorrhiza is a symbiotic association with the roots of gymnosperms. Unlike that of bacteria, the classification of fungi is based primarily on the characteristics of the sexual spores and fruiting bodies present during the sexual stages of their jycota cycles.

However, the kngdom or perfect life cycles of many fungi are as yet unknown. Based on the spore bearing structures, in which the spores are produced, fungi are classified into four divisions.

A sac like structure called ascus produces or bears sexual spores called ascospores. Sexual reproduction occurs by single celled or multi-celled conidia. Also known as sac fungi. Hyphae are generally septate. Saccharomyces, Arthroderma, Gibberella Basidiomycota Club fungi: Sexual spores called basidiospores are produced externally on a club shaped Asexual reproduction occurs by budding, fragmentation or conidia formation They are commonly called as mushroom group.

Classification of Division Mycota | Fungi

Amanita, Agaricus, Filobasidiella Zygomycota Zygote forming fungi: Sexual spore called Zygospore is formed by the fusion of two similar cells. Asexual reproduction occurs by sporangiospore Hypahe are generally aseptate. These fungi are also known as fungi imperfecti. No sexual stage is present. Asexual reproduction occurs by means of conidia.

Kingdom Mycota or Fungi: General characteristics and classification

They are pathogenic to most of the human beings and animals. Since fungi are also decomposers, along with bacteria, they play a major role in recycling the dead and decayed matter.


Penicillin antibiotic is derived from a common fungi Penicillium. Many other antibiotics like cephalosporin, griseofulvin etc. Many mushrooms are used as food by humans. Mushroom species are edible and are cultured in many parts of the world for sale. Different types of food like kimchi, kinema, bakery products, brewery products are manufactured using fungi like Aspergillusyeast etc.

Fungi are used to parasitise or kill myclta which help control pests.

Spores of fungi are sprayed on crops, this method is cheaper and environment friendly. Plant and Animal Diseases: Many fungi live on and mycoga plants and animals causing diseases like blight disease in potato, rust disease in wheat, oral thrush and ringworm infection in humans etc.

Fungal damage is responsible for large losses of stored food usually when the food contains moisture and sugar. Kingdom Mycota or Fungi: General characteristics and classification. Principle, Procedure and Applications.
