Fungal spores on a lemon grass (Cymbopogon citratus) leaf, coloured scanning electron micrograph (SEM). Also seen are several stomata, minute holes used in gas exchange. Some species of fungi are parasitic on plants, causing diseases that include rusts, smuts and mildews. The spores (brown) are the fungal reproductive bodies. Lemon grass is native to India and south-eastern Asia. It is used extensively in cooking for the lemony taste it imparts to dishes. Some types of lemon grass are also used in perfumes and in insect repellents.
