In this article we will discuss about vegetative structures of alternaria. 1. Mycelium of the fungus is intercellular or intracellular. 2. Light-brown coloured hyphae are well-branched, septate, and each cell is multinucleate (Fig. 111). 3. Haustoria are absent. Conidia: Fungus reproduces only be asexual reproductive bodÂies called conidia, which show following characters: 1. These are present (Fig. 112) terminally on [...]
In this article we will discuss about vegetative structures of agaricus. 1. Vegetative mycelium grows within the soil. 2. The primary mycelium is septate, haploid, short lived, and each cell contains oil globules, vacuoles and one nucleus. 3. The secondary mycelium is dikaryotic and long-lived. 4. The hyphae of the secondary mycelium are long, branched and remain twisted to form [...]
In this article we will discuss about the asexual and sexual reproductive structure of penicillium. Asexual Reproduction of Penicillium: 1. Asexual reproduction takes place by conidia. 2. Conidia develop on branched, septate and multinucleate conidiophores. 3. A conidiophore is an erect body developed from any cell of the mycelium. 4. Brush-like apical portion of the conidiopnore is known as penicillus, [...]
