Tulsi is cultivated for religious and traditional medicine purposes by every household in India. It has a place within the Hindu traditions, in which devotees perform worship involving holy basil plants or leaves.
I also have tulsi plants are grown in my balcony, last Sunday morning, I observed white cottony hoar-frost fungal growth on the stem of Tulsi plant (Fig. 1).

I took a glass slide, which I always keep at home along with foldscope kit, and transferred the fungal growth from the stem to slide using a needle. After observing it under foldscope, I could see lateral fertile branches in acropetal order (Fig. 3).

After using the digital zoom function of my smartphone, I could capture the conidia, which were hyaline and oval in shape, and often found in clusters (Fig. 4).
