This is an extremely common, widely distributed, wood decaying, bracket fungi. It is saprobic, occurring on stumps, logs, and sticks of mostly hardwood trees, especially oak. It occasionally occurs on living trees and conifers. It is highly variable in form and color, making positive identification difficult. It may be found in groups, rows, shelves, or dense overlapping clusters.

There is no stalk.

The fruiting body is often a thin, semicircular or fan-shaped, 3 16 to 1½ wide or slightly wider bracket (cap). It is leathery and pliant when moist, rigid when dry. It may be flat, wavy, or curved up at the sides in the shape of a sliced funnel. Sometimes adjacent brackets fuse together forming a lobed shelf up to 4 long or longer. The upper surface is dry and concentrically zoned with different colors and textures. When young and moist it is shades orangish-brown, reddish-brown, tawny, or cinnamon. When dry it is buff to gray. Older specimens may develop greenish shades due to a covering of algae. It is densely covered with velvety or appressed hairs but often hairless or nearly hairless near the margins. As it ages the hairs wear away.

The under surface is smooth or slightly bumpy, with no layer of pores or tubes. It is orange, orangish-buff or tawny to yellow or yellowish-orange with a brownish tinge. It often becomes dark brown to chestnut brown with age.

The flesh is thin, tough, and inedible. When cut, young caps do not bleed a red liquid.

The spore print is white but difficult to obtain.


False Turkey Tail (Stereum ostrea) caps are usually larger, 2 to 3 wide, and are more prominently zoned in concentric rings of contrasting colors. They usually form individual brackets and do not fuse together. The underside is buff to cinnamon-buff when young.

Výskyt leden až prosinec velmi hojně v listnatých lesích na nevápenité půdě, v cerových dubinách, šipákových a teplomilných doubravách, v kyselých doubravách ale i ve vápnomilných a orchidejových bučinách na mrtvých kmenech listnáčů, vzácněji jehličnanů. Je nejedlý.

Google Translation: Incidence January to December abundant in deciduous forests on nevápenité soil, cerových dubinách, šipákových and thermophilic oak woods, oak woods in the acidic but also calcareous beech woods and orchid on dead trunks of deciduous trees, rarely conifers. It's inedible.

  Ciuperci din Romania, Stereum hirsutum
Adrian Manolache

Published on Oct 15, 2015

Biolog, dar nu si micolog, incerc sa realizez o Enciclopedie Video a Ciupercilor din Romania. Colind zile intregi prin paduri, munti, dealuri, poieni in cautare de ciuperci, in special necunoscute. Nu ma grabesc cu sistematizarea lor, fiind inca fascinat de surprizele care ma asteapta aproape zilnic. Lipsa unor lucrari ample de micologie cu zona Carpatilor, ma aduce deseori in fata unor necunoscute. Unor ciuperci necunoscute. In Regnul Fungi, lucrurile se schimba astazi, aproape total. Se incearca o noua clasificare pe baze de caracteristici genetice si toata sistematica e in aer. Pentru un ciupercar obisnuit care colinda dupa un cos de ciuperci lucrurile acestea nu conteaza. Crede el. Dar, lumea ciupercilor e mult mai complexa. De pilda, ciuperci considerate comestibile pana acum cativa ani, s-au dovedit ca au efecte nocive sau chiar letale, in timp. Exista nenumarate ciuperci necunoscute lui, toxice, necomestibile, letale sau indiferente asemanatoare cu ciupercile comestibile si care pot sa il puna intr-o situatie neplacuta. Vremea, soarele puternic, ploile intense, locatia te pot pacali in identificarea unor ciuperci. Insasi faptul ca in cataloage diferite sunt ciuperci considerate comestibile de unii autori si toxice sau necomestibile de altii, pune in dificultate pe toata lumea. Cel mai greu este insa sa suporti superficialitatea oamenilor atunci cand e vorba de ciuperci. Unii devin violenti verbal sau chiar fizic daca incerci sa le salvezi viata aruncandu-le din cos o ciuperca cu probleme, altii te injura in comentarii pentru ca "ei stiu mai bine". Cei mai multi imi trimit mii de fotografii cu ciuperci sa le spun daca sunt comestibile sau nu. E imposibil sa ii faci sa inteleaga ca nu poti sa le risti viata dupa o simpla poza. In treizeci de ani de biologie si in trei ani de micologie practica am invatat ca in lumea ciupercilor trebuie sa te feresti de cel care spune "eu stiu". Eu nu stiu ciuperci si le multumesc celor care ma ajuta uneori cu identificarea si determinarea lor.

Google Translation: Biologist, but not mycologist, trying to do a Video Encyclopedia of Mushrooms of Romania. Carol for days through forests, mountains, hills, meadows in search of mushrooms, especially strangers. Do not hurry with their systematic, they are still fascinated by the surprises waiting for me almost every day. Lack of comprehensive mycology works with the Carpathians, often brings me in front of strangers. Mushrooms unknown. The fungus, things change today, almost totally. Is trying a new classification base and all systematic genetic characteristics is in the sky. For a mushroom commonly wandering a basket of mushrooms after these things do not matter. Believe it. But fungi world is much more complex. For instance, considered edible mushrooms few years ago, proved to have harmful or even fatal, in time. There's countless unknown mushrooms, poisonous, inedible lethal or indifferent similar edible mushrooms that can put it in a bad situation. The weather, sun, intense rains, I can fool location in identifying mushrooms. The very fact that different catalogs are considered edible mushrooms and some authors toxic or inedible others embarrass everyone. It is hardest to bear superficiality people but when it comes to mushrooms. Some become violent verbal or even physical life if you try to save them by throwing them from the basket a fungus problems, others swear you in comments because "they know better". Most send my thousands of photos of mushrooms are edible if you tell them or not. It's impossible to make them understand that they can not risk their lives by a simple picture. In thirty years of biology and mycology three years of practice I learned that the world of fungi must stay away from the one who says "I know". I do not know mushrooms and thank those who help me sometimes with their identification and determination.
