Mucor: Important feature and life cycle

Mucor L. (1953), also called as black mould or pin-mould, belongs to the subdivision Zygomycotina, class Zygomycetes, order Mucorales and family Mucoraceae. Mucoralean species have a well-developed mycelium that is generally aseptate. Mucorales can also be separated from other orders of Zygomycetes by their relatively non-specialized associations with other organisms, besides a combination of their asexual and sexual reproductive structures. The mucoralean genera produce non-apophysate sporangia, with either deliquescent or persistent walls.

Pythium: Important features and life cycle

Pythium is one the important genera of class Oomycetes and has more than 100 species. The fungus occurs as a saprobe, as well as a parasite, on a wide range of habitats and organisms. The mycelium is highly branched, coenocytic, multinucleate, both intercellular and intracellular (in case of parasitic species). Haustoria are absent but appressoria are found in certain few species. The cell wall is composed mainly of β- glucans. Asexually it reproduces by means of biflagellate zoospores produced within zoosporangia.
