Phlebia tremellosa (formerly Merulius tremellosus), commonly known as trembling Merulius or jelly rot, is a species of fungus in the family Meruliaceae. It is a common and widely distributed wood-decay fungus that grows on the rotting wood of both hardwood and conifer plants.

Taxonomy

[edit]

The fungus was originally described in 1794 by German botanist Heinrich Adolf Schrader, who called it Merulius tremellosus.[2] Nakasone and Burdsall transferred the taxon to the genus Phlebia in 1984, when they placed Merulius in synonymy.[3]

It is commonly known as the "trembling Merulius",[4] or "jelly rot".[5]

Description

[edit]

Fruit bodies of the fungus are fan-shaped to semicircular, measuring 2–4 cm (3⁄4–1+5⁄8 in) wide by 5–10 cm (2–3+7⁄8 in) long. They have a spongy to fibrous texture, comprising stalkless caps or spreading crusts. The upper surface, white to pale yellow in colour, can be dry to moist, and hairy to woolly; the margin is usually white to translucent.[6] The undersurface, bearing the fertile hymenium, features radiating to wrinkled ridges and cross veins, and often forms pore-like depressions on mature specimens. Its colour is yellowish orange or pinkish orange. The flesh of this fungus is about 2 mm thick, with a fleshy to gelatinous texture and white to yellowish colour.[4]

In Dutch, the mushroom is known as bacon-pork rind mushroom because of the resembling with a piece of bacon.[7] It is inedible.[8]

Habitat and distribution

[edit]

Phlebia tremellosa is found in Asia, Europe, North Africa, North America, and South America. It is a white rot species that grows on the stumps, fallen branches, and logs of both hardwoods and conifers.[5]
