Trembling Phlebia: Identification Guide For Jelly Rot Fungus

Jelly rot or trembling Phlebia (Phlebia tremellosa) grows throughout North America, Europe, and Asia. It is a wood-decay fungus that spreads naturally across fallen trunks and branches of deciduous hardwoods. It sometimes appears on conifers, too. This fungus doesn’t look like a traditional mushroom; it doesn’t have a clearly defined cap, gills, or stem. Instead, it grows like a crust on wood surfaces and is distinguished by how its upper edge folds over.
