    on L-arabinoze medium. A single stalked, lemon shaped and papillate initial cell seems to take part in the formation of pycnidium. The apical papilla of initial cell elongates so as to give the initial a central position flanked by hyphae. This single initial by successive divisions becomes an oval pycnidial primordium (trichomeristogenous). Further enlargement of pycnidium seems to take place due to mechanical force exerted by successive conidial formation. At maturity, the pycnidium is melanized. Some primordia abort leaving behind ghost pycnidia in the central disc. The minimal supplemented media like L-arabinoze medium reduce vegetative growthgrowthSubject Category: Natural Processes
