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 life cycle of penicillium with the help of suitable diagrams. Mycelium of Penicillium: The mycelium is well developed and copiously branched. It is composed of colourless, slender, tubular, branched and septate hyphae. The hyphae run in all directions on the substratum and become intertwined with one another to form a loose network [...]
In this article we will discuss about:- 1. Occurrence of Aspergillus 2. General Characteristics of Aspergillales 3. Salient Features. Occurrence of Aspergillus: This fungus is also called Eurotium. It is chiefly a saprophytic fungus which is widely distributed. It grows on decaying vegetables; on fatty media such as butter and ghee; on starchy media as bread and rice; on preserved [...]
