The following points highlight the seven main evolutionary tendencies of Ascomycetes. (i) The gradual transition from the aquatic forms to purely terrestrial species noticeable in the Phycomycetes culminates in the Ascomycetes which are fungi of drier, terrestrial habitats completely lacking motile cells in their life cycle. (ii) The tendency towards increased septation of hyphae in the advanced Zygomycetes becomes firmly [...]
In this article we will discuss about the reproduction in ascobolus with the help of suitable diagrams. Mycelium of Ascobolus: The mycelium of the fungus is well developed and ramifies in the substratum forming complex hyphal masses. The mycelium is septate with multinucleate cells and branched. The complex hyphal mass absorbs the food material from the substratum and supplies to [...]
In this article we will discuss about the sexual reproduction in coprobia with the help of suitable diagrams. It varies in different species of Humaria. In Coprobia granulatus only the female sex organ is developed. It is called the ascogonium. The antheridium is lacking. The mature ascogonium is a multinucleate, oval structure. It has no trichogyne. It is borne at [...]
