The Extracellular Indolic Compounds of Lentinus edodes

In macrobasidial fungi, the properties of compounds of a phytohormonal nature, which are well known in higher plants and are intensively studied in soil associative microorganisms, are only described in an unsystematic manner and, apparently, to an insufficient degree. Auxins are the most studied group of phytohormonal substances. As an object of research, along with other mycological objects of industrial cultivation, the higher fungus–xylotrophic basidiomycete Lentinus edodes (Berk.) Sing (Lentinula edodes (Berk.) Pegler or shiitake), which is of high practical importance and the physiological and biochemical characteristics of which are obviously insufficiently studied, is of particular interest.
