This textbook is a crisp compilation for the students of Botany Honours Program. Mycology and Phytopathology being one of the core subjects, students often struggle with the amount of information available since they have very limited time to study. The author has attempted to include optimum amount of study material along with sufficient number of figures and tables. This textbook covers the fundamental as well as applied aspects of fungi. Model questions are given at the end. Simple language and to the point content as per CBCS Curriculum are the main features.
