Leafy shiver (Tremella foliacea)

Description

Fruit body: 5-15 centimeters and more, the shape is varied, it can be correct, from spherical to cushion-shaped, it can be irregular, depending on the growth conditions. The body of the fungus consists of a mass of leaf-like formations that have grown together with a common base; in young specimens, until they have lost their elasticity, they give the impression of 'ruffled' thin combs. The surface is oily-moist in damp weather, in dry periods it remains wet for a long time, when dry, individual petals wrinkle in different ways, so that the shape of the fruit body is constantly changing.

Color: brownish, maroon to cinnamon brown, darker in age. When dry, they can acquire a light purple tint, later darken to almost black.

Flesh: translucent, gelatinous, firm. With the aging of the fruit body in wet weather, the 'petals' from which the mushroom is formed lose their elasticity and shape, and in dry weather they become fragile.

Smell and taste: No particular taste or smell, sometimes described as 'mild'.

The spore-bearing layer is located over the entire surface. Spores: 7-8.5 x 6-8.5 μm, subglobose to oval, smooth, non-amyloid. Spore powder: cream to pale yellowish.

Ecology

The leaf tremor parasitizes other fungi of the Stereum species growing on conifers, for example, Stereum sanguinolentum (Reddening Stereum). Therefore, Phaeotremella foliacea can only be found on conifers (stumps, large valezha).

Season and distribution

Widespread in Eurasia, America. The fungus can be found at different times of the year in varying degrees of growth or dying, since the fruiting bodies persist for a long time.

Edibility

The mushroom is probably not poisonous, but its taste is so low that the question of preparation is not particularly considered.

Similar species

Deciduous shiver (Phaeotremella frondosa)

It dwells exclusively on deciduous species, as it parasitizes types of stereums attached to deciduous species. Auricularia auricular (Judas ear) (Auricularia auricula-judae)

Differs in the shape of fruit bodies. Sparassis crispa

It has a much firmer texture, is yellowish brown rather than brown, and usually grows at the base of conifers rather than directly on the wood.

Note: a bit of history The taxonomy of the Phaeotremella foliacea group is being revised based on morphological, ecological, geographic and DNA data. The name P. foliacea is reserved for the gymnosperm species associated with Stereum sanguinolentum in Eurasia and North America. Tremella neofoliacea and Cryptococcus skinneri are considered synonymous with P. foliacea s.str. The other three species in the complex are inhabited by deciduous trees. Of these, Phaeotremella fimbriata, comb. nov. , associated with Stereum rugosum; this species has a blackening of basidiocarps and small basidiospores, found in Europe. Its close relative is the East Asian Phaeotremella eugeniae, sp. nov. is associated with the Mongolian oak (Quercus mongolica) and has larger basidiospores. The third species, Phaeotremella frondosa, comb. nov., produces the largest basidiospores in the genus and is associated with either S. rugosum (mainly in Northern Europe) or other Stereum species (temperate Eurasia and North America). In addition, T. nigrescens is typed and synonymous with P. frondosa, and two species, T. fuscosuccinea and T. roseotincta, are combined with Phaeotremella.

– comb. nov. (abbreviated from Lat. Combinatio nova) – a new combination, that is, a combination formed from the previously promulgated legal name

– sp. nov. (abbreviated from Lat. Species nova) – a new species. The phrase is used after the binomial name, which is published for the first time.
