Description
 
 

Trametes pubescens is a small, common, and widely distributed bracket fungus. It is found July through October, alone or in groups. It is saprobic, occurring on stumps and fallen logs of dead hardwood trees.

There is no stem or just a rudimentary stem.

The cap is fan-shaped, semicircular, or kidney-shaped, up to 3 wide and up to 2 deep. It sometimes fuses with adjacent caps. The upper side is creamy white to grayish-yellow with faint textural zones but without contrasting zones of color. It is densely silky hairy or velvety to finely velvety when young, becoming nearly hairless with age. It often has fine furrows radiating toward the margin, especially near the margin.

The underside (pore surface) is creamy white when young, turning yellowish with age. There are 3 to 5 angular pores per mm (about 1 32). The pores are very small but plainly visible.

The flesh is whitish, tough, and watery when fresh, becoming dry, rigid, and corky. It is inedible.

 
     
 

Similar Species

 
  Hairy Bracket (Trametes hirsuta) is larger, up to 6 wide. The cap and margin are not radially striate. The margin is often brownish, brown, or blackish. The pore surface becomes, brownish, grayish, or yellowish with age.

Four species, Trametes pubescens, Trametes ochracea, Trametes ectypa, and Turkey Tail (Trametes versicolor), form a species complex. The species are morphologically very similar, differing only in the color and texture of the upperside of the bracket. They are also genetically distinct – they are not sexually compatible.

Published on Nov 17, 2014

Este foarte asemanatoare cu ciuperca medicinala trametes versicolor 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: It is very similar medicinal mushroom Trametes versicolor 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.
