Cladonia chloropaea is a fungus in the family Caryophyllaceae. The primary lichens persist or disappear, ranging from small to medium-sized, with no powdery sprouts or a few powdery sprouts visible on the ventral surface. The stem of the seed vessel is 1-3 cm high, and the tip gradually enlarges into a trumpet shaped cup. It forms a smaller cup either singly or by sprouting from the edge of the cup. The cup without a seed sac is the entire rim; The lower part of the stem has a continuous cortex, which may be wart like or granular. As it reaches the upper part, the cortex becomes more and more detached, exposing the marrow layer. There are many granular powder buds on the cup side or inside the cup.
