Description

The shiny cinnamon polypore (Coltricia cinnamomea) is a close relative of the tiger's eye (C. perennis), also a small saprotrophic polypore with a distinctive clearly zoned, concentrically banded cap, but with a predominantly dark chestnut-cinnamon coloring. The Latin epithet cinnamomea means "cinnamon-colored", and the name fits: the fruiting body's main tone is cinnamon-chestnut, deep brown, without the bright light-orange bands typical of C. perennis.

Inedible — the flesh is tough, leathery and cardboard-like, as in other Coltricia. It has no culinary value and foragers don't pick it. It is interesting mainly to mycologists, as an indicator of broadleaf forests with acidic soils.

Key features of Coltricia cinnamomea: Small (1-4 cm) fruiting body on a thin stem Concentrically banded upper surface with dark cinnamon and ochre-brown zones (darker and more uniform than in C. perennis) Underside with fine pores (a polypore) Flesh very thin, leathery, brownish-ochre Grows in broadleaf forests (oak, beech, hornbeam), the key difference from C. perennis (which grows in pine forests) Often forms distinctive "fairy rings" on bare soil

The main thing is to recognize it as an indicator of forests with acidic soils and not to confuse it with closely related Coltricia species. In the wild the two (C. perennis and C. cinnamomea) are often confused because they look alike; the key difference is habitat: pine forests = C. perennis, broadleaf forests = C. cinnamomea.

In Ukraine, Coltricia cinnamomea is common in broadleaf and mixed forests: the Carpathians, Prykarpattia, Polissia, the forest-steppe. Season: July to October, and the fruiting bodies last a long time.

Cap

Cap 1-4 cm across, thin, leathery, flat and spread out with a slightly sunken center. Surface matte and dry, with fine felty fibers. Clearly zoned, concentrically banded, dominated by dark cinnamon, chestnut and ochre-brown zones. The base color is cinnamon-chestnut to dark brown, richer in the center. The margin is even, wavy in mature specimens.

Hymenophore

Pored hymenophore: fine, small pores on the underside of the cap (~3-5 pores/mm). Color brownish-ochre to cinnamon. Spore print brown.

Stem

Stem 1-3 cm tall, 0.3-0.7 cm thick, thin, cylindrical. Color dark cinnamon to blackish-brown, with fine felty down. Surface dry and matte.

Flesh

Flesh very thin, leathery, tough, brownish-ochre, cardboard-like. Not fit for cooking. Smell faint, neutral.

Smell

Faint, neutral, nothing distinctive.

Lookalikes

Mushrooms of the same genus and habitat — to study side by side and never mix up.

Frequently asked questions

Is it poisonous?

Not poisonous, but inedible because of its tough, leathery flesh.

How do you tell it apart from C. perennis?

By habitat and color. C. cinnamomea: darker cinnamon-chestnut, in broadleaf forests (oak, beech, hornbeam). C. perennis: with distinct orange-ochre bands, in pine forests. They are often confused, so the key check is the forest type.

Where can you find it, so you'll recognize it?

On soil in broadleaf forests (oak, beech, hornbeam), in bare patches, along forest edges. It often forms "fairy rings" of 10-20 fruiting bodies.

Which regions of Ukraine is it found in?

Common throughout the forest zone: the Carpathians, Prykarpattia, Polissia, the forest-steppe.

When can you come across it?

July to October; the fruiting bodies last a long time and can be seen even in winter.

What mushrooms is it confused with?

With C. perennis — in pine forests, lighter in color. With Onnia tomentosa — larger, on conifer roots.

Is Shiny cinnamon polypore edible or poisonous?
Shiny cinnamon polypore is inedible. Before eating any wild mushroom, always double-check current information in reliable sources and consult an expert.
Does Shiny cinnamon polypore have gills or pores?

What does the cap of Shiny cinnamon polypore look like?
Cap 1-4 cm across, thin, leathery, flat and spread out with a slightly sunken center. Surface matte and dry, with fine felty fibers. Clearly zoned, concentrically banded, dominated by dark cinnamon, chestnut and ochre-brown zones.
What does the stem of Shiny cinnamon polypore look like?
Stem 1-3 cm tall, 0.3-0.7 cm thick, thin, cylindrical. Color dark cinnamon to blackish-brown, with fine felty down. Surface dry and matte.
What do Shiny cinnamon polypore smell and taste like?
Faint, neutral, nothing distinctive. Taste: mild.
Where does Shiny cinnamon polypore grow?
Typical habitats: Deciduous forest, Mixed forest.
