Abstract
Mushrooms are large, fleshy, edible fungi that belong to the Ascomycetes or Basidiomycetes classes. Among them, milky mushrooms (Calocybe indica) are the third most commercially cultivated variety in Pakistan, following button and oyster mushrooms. This study aimed to identify the most effective growing medium and grain substrate for the culture and spawn preparation of milky mushrooms. Three media Potato Dextrose Agar (PDA), malt extract agar, and Czapek Dox Agar (CDA) were evaluated for their influence on mycelial growth. The treatments were designated as T1 (PDA), T2 (MEA), and T3 (CDA). PDA showed significantly superior results in promoting cultural growth. Mycelial development was observed on days 4, 7, and 10. Additionally, grain substrates were assessed, revealing that wheat grains supported the maximum mycelial growth, while oat grains showed the least growth on days 7, 14, and 21. These findings suggest that PDA and wheat grains are the most suitable for mass multiplication of C. indica.
