The conceptual origins of microbiology can be traced back to ancient Indian knowledge systems, particularly the Vedas and classical Ayurvedic texts. According to Frend (2006), the Vedas are among the earliest recorded scriptures on Earth, regarded not merely as human compositions but as divine revelations. Within these texts, renowned Vedic sages—such as Agastya, Manu, Charaka, Sushruta, and Vagbhata—have laid the foundational understanding of disease causation and microbial life through the concept of Krimi. As elaborated in the Charaka Samhita, Sushruta Samhita, Ashtanga Hridaya, and Ashtanga Samgraha, Krimis* are described as both visible and invisible organisms, with detailed classifications based on their morphology (shape, color), habitat (internal and external), and their physiological impacts on humans, animals, and plants. These early texts also discuss the etiology of infections, including environmental and dietary causes, and recommend remedies involving herbal formulations, detoxification processes, and hygienic practices (Frend 2006; WisdomLib, 2023).

Furthermore, the Vedic literature alludes to fungi through references to Soma, a sacred and possibly psychoactive or pathogenic substance, believed by some scholars to be fungal in origin (Sharma 2000; Deogade MS, Kethamakka 2019; Ahirrao & Patil 2022). Ayurvedic literature provides an early understanding of mycology, distinguishing between edible mushrooms, wood-decaying fungi, and pathogenic species. Ethnomycological documentation includes some of the earliest reports of polypores from India, notably Hexagonia sinensis and Polyporus wightii (Sharma 2000; Vaidya & Lamrood 2000; Tejal et al. 2020). These observations strongly support the view that the Indian subcontinent was not only aware of microbial and fungal life forms in ancient times but also systematized this knowledge long before the formal establishment of modern microbiology. *https://vedotpatti.in/samhita/Vag/vagbhata/?mod=home&con=as

Modern Indian mycology

The earliest formal records of fungi from the Indian subcontinent are attributed to Johann Gerhard Koenig, a Danish missionary and naturalist. Between approximately 1767 and 1785, Koenig collected numerous fungal specimens from Tanjore (now Thanjavur) Tamil Nadu. One of the earliest described species was Lycoperdon pistillare, initially classified by Linnaeus. This species was later reclassified by Persoon into the genus Scleroderma and subsequently transferred to Podaxon by Fries (Butler & Bisby, 1931).
