Description
 
 

Trembling Phlebia is a wood-rotting fungus. It is found in Europe, Asia, and North and Central America. In the united States it is common from the East Coast to the Midwest and on the West Coast. It is less common in Minnesota, where it is at the western edge of its range. It obtains its nutrients from dead wood (saprobic). It grows flat (resupinate), alone or in groups, mostly on stumps and fallen branches of deciduous trees, especially oak and beech, occasionally also on wood of coniferous trees. It sometimes appears in overlapping clusters.

The fruiting body is a 2 to 4 long, ¾ to 1½ wide, irregularly shaped patch of pore surface spread out flat (effused) on a branch or log (substrate). It is pale and lies completely flat (resupinate) when young. As it matures it darkens and the upper edge folds back more than 90° creating a bracket-like cap. Adjacent patches often fuse together covering extensive areas.

The lower surface is the only visible part when no caps are present. It is yellowish to brownish-orange to pinkish-orange when young, becoming orange to red when mature. The flesh is translucent, flexible, rubbery, and somewhat jelly-like. It has a shallow, elaborate network of narrow ridges, 1 32 to 1 16 wide furrows, and crossveins. It looks something like a tube surfacebut unlike a true tube surface, spore-producing structures (basidia) cover the entire networked layer.

The caps, when present, are narrow, up to ¾ long, white to pale yellow, and densely covered with woolly hairs. There is no stem.

The flesh is very thin, whitish, and waxy or gelatinous. It is not edible.

The spore print is white.

This species was formerly classified as Merulius tremellosus. In 1984 it was transferred to the genus Phlebia. A recent DNA study (Monclavo et al., 2002) showed the the genus Phlebia is probably poluphyletic, containing unrelated species. However, Phlebia tremellosa is part of a group that clearly belongs to the genus Phlebia.

Resupinate

In fungi: referring to the fruiting body lying flat on the surface of the substrate, without a stalk or a cap.

 

Saprobic

Obtaining nutrients from non-living organic matter, such as decaying plant or animal matter.

Phlebia means "veins"; tremellosa means "trembling."

Its typical form is a classic example of what mycologists call an "effused-reflexed" fruiting body; it spreads its spore-bearing surface over the wood and musters up just enough cap-making umph to fold over its upper edge into a slight extension. Other distinguishing features include the translucent, orangish to pinkish spore-bearing surface, which develops deep folds and pockets; the whitish, hairy upper edge; growing alone to gregariously, sometimes in overlapping clusters; found primarily on the dead wood of hardwoods but also reported on conifer wood; causing a white rot; See more: http://www.mushroomexpert.com/phlebia_tremellosa.html

Upper surface: Caps white to pale yellow; hairy, wooly. Pore surface: Pore-like with a network of radiating folds, ridges, and crossveins; yellowish to brownish-orange to pinkish-orange; rubbery, flexible, and gelatinous. Edibility: Inedible. : https://www.messiah.edu/Oakes/fungi_on_wood//poroid%20fungi/species%20pages/Phlebia%20tremellosa.htm

Caps white to pale yellow; hairy, woolly. These soft and flexible bracket-like growths often fuse laterally to form more extensive sheets. Habitat : Mostly on decaying deciduous wood. Fairly frequent and widespread in Britain. See more: https://www.naturespot.org.uk/species/jelly-rot-fungus
