In this article we will discuss about the classification of lower fungi. The modern mycologists consider that the class Phycomycetes is not a natural group of closely related forms. Numerous new proposals for regrouping them are thus forthcoming. Sparrow (1958-59) suggested that the order Plasmodiophorales which includes the endoparasitic slime molds should be given the rank of a class Plasmodiophoromycetes [...]
In this article we will discuss about the evolution of thallus in lower fungi with the help of diagrams. In the simplest and primitive members, which are aquatic, there is no mycelium. The thallus in these forms is microscopic and unicellular. In Olpidium endogenum, it consists of a tiny mass of naked, uninucleate protoplast which enters the host cell, enlarges [...]
The following points highlight the two main kinds of mycelia in fungi. The kinds are: 1. Aseptate Mycelium 2. Septate Mycelium. Kind # 1. Aseptate Mycelium (Fig. 1.2): In the algal fungi (Phycomycetes) the mycelium in the vegetative phase usually lacks internal partitions of any kind. The hyphae are thus multinucleate and aseptate. The mycelium is a continuous mass. It [...]
