Species Fungorum gives <em>Inonotus obliquus<\/em> (Fr.) Pil\u00e1t as the current scientific name and places the species in the family Hymenochaetaceae.\n<\/p>\n<p>\nThe species lives as a wood-decaying and parasitic fungus on trees. It occurs mainly on birch species, although researchers have also documented Chaga conks on other host trees.\n<\/p>\n<p>\nWhat makes Chaga unusual is that the structure people most often recognise as \u201cChaga\u201d does not look like a classic cap-and-stem mushroom.\n<\/p>\n<p>\n<strong>Instead<\/strong>, the fungus develops a dark, hard and irregular structure on the trunk. This structure is normally called a <strong>Chaga conk<\/strong>.\n<\/p>\n<\/section>\n<section id=\"vad-ar-conk\">\n<h2>What is a Chaga conk?<\/h2>\n<p>\nA <strong>Chaga conk<\/strong> is the dark outgrowth that <em>Inonotus obliquus<\/em> can form on an infected tree.\n<\/p>\n<p>\nMycological literature often uses the term <strong>sterile conk<\/strong>. This means that the structure lacks the normal reproductive function of a mature fruiting body.\n<\/p>\n<p>\nThe conk can grow for many years and over time develops a very characteristic appearance. The surface becomes dark to almost black, cracked and charcoal-like. The inner tissue, on the other hand, often has browner or rust-coloured tones.\n<\/p>\n<div class=\"information-box\">\n<p>\n<strong>Important terminology:<\/strong> \u201cChaga conk\u201d describes the raw material more accurately than \u201cChaga fruiting body\u201d when referring to the well-known black structure from the tree.\n<\/p>\n<\/div>\n<\/section>\n<section id=\"fruktkropp\">\n<h2>Is the Chaga conk a fruiting body?<\/h2>\n<p>\nNo, not in the usual mycological sense.\n<\/p>\n<p>\nA classic mushroom fruiting body acts as a reproductive structure in which the fungus produces and spreads spores. The Chaga conk does not fulfil that role but functions as a <strong>sterile structure<\/strong>.\n<\/p>\n<p>\nThis means that the well-known black Chaga lump differs from the fruiting body of, for example, Lion\u2019s Mane, Reishi or an ordinary cap mushroom.\n<\/p>\n<p>\nLater in its life cycle, <em>Inonotus obliquus<\/em> can develop an actual spore-producing structure, for example when the host tree dies. That structure looks different and does not correspond to the Chaga conk normally harvested as a raw material.\n<\/p>\n<div class=\"table-scroll\">\n<table>\n<thead>\n<tr>\n<th scope=\"col\">Structure<\/th>\n<th scope=\"col\">Chaga conk<\/th>\n<th scope=\"col\">Reproductive fruiting body<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Appearance<\/strong><\/td>\n<td>Dark, hard and irregular outgrowth<\/td>\n<td>Thinner spore-producing fungal tissue<\/td>\n<\/tr>\n<tr>\n<td><strong>Function<\/strong><\/td>\n<td>Sterile structure<\/td>\n<td>Reproduction and spore production<\/td>\n<\/tr>\n<tr>\n<td><strong>Common Chaga raw material?<\/strong><\/td>\n<td>Yes<\/td>\n<td>No<\/td>\n<\/tr>\n<tr>\n<td><strong>Common product term<\/strong><\/td>\n<td>Chaga conk<\/td>\n<td>Fruiting body<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/section>\n<section id=\"bjork\">\n<h2>Why is Chaga associated with birch?<\/h2>\n<p>\nChaga is strongly associated with the birch genus <em>Betula<\/em>. Researchers have, for example, examined conks from silver birch, <em>Betula pendula<\/em>, and downy birch, <em>Betula pubescens<\/em>.\n<\/p>\n<p>\nAt the same time, Chaga can also occur on other deciduous trees. One comparative study analysed conks from both <em>Betula<\/em> and <em>Alnus<\/em>, that is, alder.\n<\/p>\n<p>\n<strong>Interestingly<\/strong>, the study showed that the host tree could affect parts of Chaga\u2019s chemical profile. The researchers observed differences in betulinic acid and certain polyphenolic components between samples from birch and alder, among other things.\n<\/p>\n<p>\nThis means that <strong>host tree and geographical origin can contribute relevant information to the raw material documentation<\/strong>.\n<\/p>\n<\/section>\n<section id=\"utsida-insida\">\n<h2>The outside and inside of a Chaga conk are not identical<\/h2>\n<p>\nA mature Chaga conk has a clearly layered appearance.\n<\/p>\n<p>\nThe surface is usually dark, hard and cracked. Inside, however, there is brown to rust-coloured tissue.\n<\/p>\n<p>\nChemical analyses also show that different parts of the Chaga conk can contain different concentrations of certain triterpenoids.\n<\/p>\n<p>\nIn one study, researchers compared the outer and inner parts of <em>Inonotus obliquus<\/em>. They found differences in the triterpenoid profile, including compounds such as inotodiol, betulin, betulinic acid and trametenolic acid.\n<\/p>\n<p>\n<strong>That is why<\/strong> even where in the conk a sample is taken can affect the analytical result.\n<\/p>\n<\/section>\n<section id=\"inotodiol\">\n<h2>Inotodiol \u2013 a characteristic Chaga marker<\/h2>\n<p>\n<strong>Inotodiol<\/strong> is a lanostane-type triterpenoid that researchers often identify in <em>Inonotus obliquus<\/em>.\n<\/p>\n<p>\nSeveral chemical studies of Chaga return to this compound. Inotodiol therefore works as a relevant raw material marker in analytical characterisation.\n<\/p>\n<p>\nStudies of Chaga from different geographical areas also show that the amount of inotodiol can vary between samples. Researchers have, for example, compared Chaga from France, Ukraine and Canada and measured different concentrations of inotodiol, betulin and betulinic acid.\n<\/p>\n<p>\n<strong>This illustrates an important principle:<\/strong> the species name alone does not guarantee an identical chemical profile in every batch of raw material.\n<\/p>\n<div class=\"important-notice\">\n<p>\n<strong>An analytical marker is not the same as a measure of effect.<\/strong> Inotodiol can describe parts of the raw material\u2019s chemical profile, but a specified inotodiol value does not in itself say anything about medical or physiological effect.\n<\/p>\n<\/div>\n<\/section>\n<section id=\"betulin\">\n<h2>Betulin and betulinic acid in Chaga<\/h2>\n<p>\nBetulin and betulinic acid are two other compounds that often appear in analyses of Chaga.\n<\/p>\n<p>\nBirch bark naturally contains large amounts of betulin. Because <em>Inonotus obliquus<\/em> often develops on birch, researchers have long studied the relationship between the host tree and these triterpenoids in Chaga material.\n<\/p>\n<p>\nChemical studies have shown both <strong>betulin<\/strong> and <strong>betulinic acid<\/strong> in Chaga conks. At the same time, the levels vary depending on, among other things, the origin of the sample and the host tree.\n<\/p>\n<p>\nA documented analytical value for a specific raw material therefore gives more information than the assumption that all Chaga has the same triterpenoid profile.\n<\/p>\n<\/section>\n<section id=\"beta-glukaner\">\n<h2>Beta-glucans in Chaga conk<\/h2>\n<p>\nChaga also contains glucans and other polysaccharides.\n<\/p>\n<p>\nBeta-glucans act as structural components of fungal tissue. Laboratories can therefore analyse the beta-glucan content as part of the chemical characterisation of the raw material.\n<\/p>\n<p>\nIt is, however, important to distinguish between <strong>beta-glucans<\/strong> and the broader term <strong>polysaccharides<\/strong>. A high total value for polysaccharides does not automatically mean the same thing as a specific beta-glucan value.\n<\/p>\n<p>\nIn addition, the beta-glucan content should not be used as a universal measure of strength between different mushroom species.\n<\/p>\n<p>\nIf you would like to read more about how such analyses work, see our guide on<br \/>\n<a href=\"https:\/\/aromexperten.se\/en\/beta-glucans-mushroom-extracts\/\">beta-glucans in mushroom extracts<\/a>.\n<\/p>\n<\/section>\n<section id=\"mycel\">\n<h2>Chaga conk vs Chaga mycelium \u2013 not the same raw material<\/h2>\n<p>\nLike other fungi, <em>Inonotus obliquus<\/em> also forms mycelium. The mycelium consists of the fungus\u2019s network of hyphae and is biologically different from the Chaga conk that develops on the tree.\n<\/p>\n<p>\nYou should therefore not automatically regard a product based on Chaga mycelium as chemically identical to a product based on a naturally developed Chaga conk.\n<\/p>\n<p>\nThe difference becomes even more important when the producer grows the mycelium on grain or other solid substrates.\n<\/p>\n<p>\nIn such cases, the finished material may contain both fungal mycelium and parts of the growth substrate.\n<\/p>\n<div class=\"information-box\">\n<p>\n<strong>Raw material identity first:<\/strong> When a producer markets a product as Chaga, the documentation should clearly state whether the material consists of Chaga conk, mycelium or another type of cultivated biomass.\n<\/p>\n<\/div>\n<\/section>\n<section id=\"autentisering\">\n<h2>How can laboratories identify genuine Chaga conk?<\/h2>\n<p>\nThis has become an important area of modern Chaga analysis.\n<\/p>\n<p>\nIn an extensive study from 2025, researchers compared authentic Chaga conk with commercial Chaga products, including material based on mycelium and fermented grain.\n<\/p>\n<p>\nThe researchers combined several analytical methods, including chromatography, mass spectrometry, NMR, UV-Vis and starch analysis.\n<\/p>\n<p>\n<strong>The results showed clear chemical differences.<\/strong> Authentic Chaga conk showed, among other things, characteristic triterpenoids such as inotodiol and trametenolic acid as well as a specific melanin profile.\n<\/p>\n<p>\nFermented grain products, by contrast, had a much more starch-rich composition. The researchers could also distinguish these products from both authentic conk and pure <em>Inonotus obliquus<\/em> mycelium by their chemical fingerprint.\n<\/p>\n<p>\nThis means that modern laboratory analysis can give much more information about the identity of a Chaga raw material than the product name on the label.\n<\/p>\n<\/section>\n<section>\n<h2>Melanin and the dark surface of Chaga<\/h2>\n<p>\nThe almost black surface is one of the most characteristic features of the Chaga conk.\n<\/p>\n<p>\nDark pigments, including melanin-like components, contribute to the typical colour.\n<\/p>\n<p>\nIn the 2025 authentication study, the researchers used, among other methods, UV-Vis analysis of melanin-related absorbance to distinguish authentic Chaga conk from fermented grain products.\n<\/p>\n<p>\n<strong>This is a good example of how researchers can link a visible property of the raw material to measurable analytical parameters.<\/strong>\n<\/p>\n<\/section>\n<section id=\"kvalitet\">\n<h2>How do you assess the quality of Chaga raw material?<\/h2>\n<p>\nA Chaga product should provide much more information than just the word \u201cChaga\u201d.\n<\/p>\n<p>\nIn a technical raw material assessment, the following information is particularly valuable:<\/p>\n<ul class=\"checklist\">\n<li>correct scientific name \u2013 <em>Inonotus obliquus<\/em><\/li>\n<li>clearly stated type of raw material \u2013 for example Chaga conk<\/li>\n<li>host tree when the information is available<\/li>\n<li>geographical origin<\/li>\n<li>extraction method<\/li>\n<li>extraction medium<\/li>\n<li>specified beta-glucan content<\/li>\n<li>species-specific triterpenoid markers<\/li>\n<li>analytical methods<\/li>\n<li>microbiological specification<\/li>\n<li>heavy metal specification<\/li>\n<li>traceability and manufacturing<\/li>\n<\/ul>\n<p>\n<strong>That is why<\/strong> transparent documentation provides a much better basis than phrases such as \u201cpremium Chaga\u201d or \u201csuper-concentrated Chaga extract\u201d without further analytical data.\n<\/p>\n<\/section>\n<section id=\"extrakt\">\n<h2>What does Chaga conk mean for a Chaga extract?<\/h2>\n<p>\nWhen the producer uses Chaga conk as the starting material, the raw material needs further processing to become an extract.\n<\/p>\n<p>\nThe producer may, for example, dry and grind the conk before extraction begins.
