These have evolved from PEZAs 16 registered economic zones and 331 locator companies. Thakor Maitri M. M.Sc. 1. In ascomycetes, asexual reproduction is by the formation of conidia exogenously on conidiophores and Sexual reproduction is by conjugation between two gametangia. The diploid nucleus first divides meiotically and forms four haploid nuclei. Simpler topics are frequently tinkered with and asked in the exam. Pier Antonio Micheli is known as the Father of Mycology. Mycosphaerella, for example, has asci in its stroma.
