ADVERTISEMENTS:
In this article we will discuss about the structure of asexual and sexual reproductive structure of peziza.
Asexual Reproduction of Peziza:
1. Asexual reproduction takes place by conidia and chlamydospores.
2. The conidia are formed exogenously at the tip of conidiophores.
ADVERTISEMENTS:
3. Conidia germinate to form the new mycelium.
4. Some intercalary, thick-walled cells are formed in the mycelium. These are chlamydospores. On germination, they form new mycelium.
Sexual Reproduction of Peziza:
1. Sexual Reproduction takes place by means of antheridium and ascogonium.
2. Sexual fusion results into a bright coloured, cup-shaped, large and sessile apothecial type of fruiting body (Figs. 89, 90).
3. In vertical section of an apothecium, following structures are visible (Fig 90).
(a) Apothecium consists of mycelium with a basal hypothecium.
(b) Hymenium region consists of many fertile asci and sterile paraphyses.
(c) Sub-hymenium is made up of pseudo- parenchymatous hyphae which later on form the peridium of the cup.
(d) In each ascus are present eight uninucleate ascospores which form the new mycelium on germination.
