Phaeotremella foliacea

Morphological Features:

Fruiting body of variable size; some specimens barely reach 4 cm, while others exceeding 15 cm have been observed. It consists of a series of clustered lobes arising from a common base. When young, these lobes appear tightly packed together, but with time and maturation they become increasingly spaced apart. Color may exhibit some variability depending on the specimen's condition; at times, due to excess moisture or drought, it may display unusual hues, more pinkish or creamy. Typically, however, it is brown with a slight reddish tinge, turning dull brown over time and dark brown to blackish in its final stage.

Hymenium located on the most exposed surface of the lobes or folds, completely smooth and with a consistency similar to the less exposed areas. It ranges in color from reddish-brown to dark brown/blackish.

Stipe absent; fruits directly on the woody substrate from which it derives nutrients.

Flesh elastic and gelatinous in consistency, similar in color to the external surface; lacks any appreciable odor and is tasteless. Typically translucent.

Habitat:

This is a relatively common species in broadleaf forests, much rarer on conifers. Fruits on woody debris, old stumps, or fallen branches, primarily during the latter half of autumn and early winter, occasionally also in spring.

Observations:

The genus Tremella is characterized by its gelatinous, lobed fruiting bodies that grow on wood. This particular species is distinguished by its relatively large size for the genus and its reddish-brown to dark brown/blackish coloration. Tremella mesenterica shares the same form and consistency, but its bright yellow to orange color clearly distinguishes it from the species described here. Tremella encephala has a brain-like shape, is not lobed, and parasitizes species of the genus Stereum. It may also be confused with species of the genus Exidia.
