Exidia sugar (Exidia saccharina) photo and description

Exidia

Exidia is a widespread species of the large Auriculariaceae family; these mushrooms grow in Russian forests almost everywhere. They have a pulp similar to dense jelly and an indefinite shape of fruit chalk. They have a characteristic feature, they dry out in heat / drought, in cool rainy seasons they swell again and grow actively. Therefore, they become noticeable only in autumn and spring, although they can appear in cold, damp summers. In our region, two species are often found, both prefer alder-willow thickets, I have tasted (raw!) No taste at all!

Exidia glandular (Exidia glandulos)

Exidia glandular on birch

It is sometimes called glandular tremor. Actually, it does not look like mushrooms at all, fruiting bodies are born in the form of shapeless dense gelatinous tubercles densely adhered to wood. Growing up, as a rule, they merge into irregularly rounded or elongated blotches with clearly defined edges. The surface is glossy with numerous winding folds and peculiar rounded mini outgrowths (lat. Carrier glands).

Elastic flesh, odorless and absolutely tasteless. Colors of all shades of brown and black. Spores form over the entire surface of the fruiting bodies; therefore, drying mushrooms are often covered with a whitish spore powder. They grow on fallen trunks and thick branches of deciduous trees. Drying, they turn into a thin smoothed crust. Exidia glandular is edible and they write that it even has medicinal properties. Only eat raw!

Exidia compressed (Exidia recisa)

In Latin, "recisa" stands for abbreviation

Exidia compressed on aspen

Compressed exsidia mushrooms are compact, small (1 - 2.5 cm). Fruit bodies are rounded, wrinkled, with uneven edges and tiny, barely noticeable legs or a narrowed base. The outer surface is matt, the inner spore-forming is smooth and shiny. mobile pulp is translucent, thin, without any taste or smell. The color of the fruit bodies is brownish-yellow, orange-brown or reddish-brown, usually grows in small families, but usually does not form intergrowths. When dried, compressed significantly decreases in size, shrinks, becoming a dull dark brown color. Grows on decaying deciduous trees / branches, preferring willow trees. These nondescript woody mushrooms have hardly been studied, so their edibility is not known. Poisonous species are not described among exsidia, they are simply not edible due to their small size, unappetizing appearance and hard gelatinous pulp.
