Top 20 Most Common Mushrooms in Keila

Trumpet cup lichen has a unique appearance with a stem that tapers into a cup or trumpet-shaped cap. The cap’s shape plays a vital role in trumpet cup lichen’s reproduction. It provides a home for algae or cyanobacteria which help spread the spores and aid in photosynthesis.

Hammered shield lichen is noted for its pollution tolerance. It is a widespread grey flat lichen that is mostly found upon tree bark and occasionally rocks. Hammered shield lichen is named for the depressions within the lobe which give it a hammered appearance.

This bracket or shelf fungus grows for years on both living and dead conifer trees. Its annual growth creates distinctive rings or ridges, with a bright red or orange band separating the old layers from the current growth. Red-belted conk is only a danger to living trees if it colonizes a very deep cut or broken top.

Common powderhorn is a green to greyish-green lichen often found growing on decaying logs and on the base of trees. Common powderhorn is a hardy species that is resistant to pollution and thrives in shady urban areas.

Pseudevernia furfuracea is associated with photobionts from the green algae genus Trebouxia. It reproduces asexually by isidia. The ontogeny of isidia development and its role in CO2 gas exchange in P. furfuracea has been investigated. The preferred growing surfaces for P. furfuracea are the so-called "nutrient poor" bark trees, including birch, pine and spruce. The species has two morphologically identical varieties that are distinguished by the secondary metabolites they produce: var. ceratea Zopf. produces olivetoric acid and other physodic acids, while var. furfuracea produces physodic but not olivetoric acid. Some authors (e.g., Hale 1968) have separated the chemotypes at the species level, designating the olivetoric acid-containing specimens as Pseudevernia olivetorina, but more recent literature separates them at the varietal level.

Vulpicida pinastri usually has few, broad, irregular lobes whose edges are lined with yellow Bortensoralen. On the underside, the lichen is pale yellowish with few rhizins. Fruit bodies (Apotheciens) are very rarely trained and then have a brown disc with bearing edge. The unicellular spores are ellipsoidal to almost spherical. The yellow color is caused by the highly toxic vulpinic acid in the marrow, which probably serves as a feeding protection against snails.

Varied rag lichen grows on rocks, soil, and especially wood. Research has suggested that certain extracts from varied rag lichen can inhibit the growth of biofilms, which may lead to future commercial uses. The specific name, glauca, means "bluish-gray or green," though occasionally this species can appear a pale white color as well.

Purplepore bracket(Trichaptum abietinum) is distinctively violet when young but fades to a light cream color as it matures. (If hosting algae, specimens may even appear green at first glance.) An unusually powerful white rotter, this species eschews deciduous woods and is most commonly found sprouting on dead conifer woods. It is considered inedible.
