蝉 flower

Thistle flower is a spore of I. cicadae. After infection with nymphs, it causes the nymphs to die. The worms are filled with mycelium of the genus Corynebacterium, and the mycelium envelops the worms. Under certain conditions, the worms are formed first. Then, the spore bundle formed at the head of the worm body (which can also be formed in other parts) forms a conidia group at the top of the spore stem bundle, which is powdery and resembles a flower bud, hence the name 蝉花, which is associated with the yarrow ) Distinction, also known as female flowers. After the nymphs were infected with snails, the snails bundled from the head cluster of the worms and grew into a bundle, which was light yellow and 1.5-6.0 cm long. The front end was swollen and had a spindle shape. Its main distinguishing feature is that the branches on the conidiophores are mostly confined to the top, the bottle stems are thick and short, dense, and the conidia are large and often curved.
