Plain Agar

Flammulina velutipes fruit bodies were grown on partly decayed Populus tremuloides sawdust supplemented with wheat bran and malt extract. In each culture there was a gradation in fruit body size, which served to select test specimens at an early stage of growth. Diffusates collected in agar blocks were applied on the apex of decapitated stipes. Plain agar and dilute potato dextrose agar (PDA/2) alone had the same slight effect on growth. Lamellae placed on plain agar caused limited growth promotion. Lamellae on PDA/2 gave 100–150% more growth promotion than on plain agar during early development, but the activity decreased to zero during the middle of the stage of rapid elongation. Lamellae of that age had no effect on young stipes and the older stipes were insensitive to diffusate from young lamellae. Very small amounts of lamellae promoted stipe elongation. Potato extract alone did not stimulate production of the lamellar diffusate and glucose was less effective than the two nutrients combined. A delay of 2 h in applying lamellar diffusate reduced stipe elongation, and there was no response after 12 h delay. Pilear trama did not produce growth-promoting diffusate.

Rapid Elongation

In the mycelium of Flammulina velutipes cultured on potato–glucose solution the concentration of water-soluble protein began to decrease steeply before fruit bodies formed, but the total amount of protein per culture decreased only when fruit bodies began to elongate rapidly. The level remained very low during rapid elongation. Proteinase activity per unit weight of mycelium against milk protein and azoalbumin decreased in parallel with the concentration of mycelial protein. Activity against azure blue – hide powder was low until the onset of rapid fruit-body elongation and reached a maximum later during that phase. Azoalbumin was hydrolyzed more actively than hide powder. Proteolytic activity per gram of mycelium against mycelial protein was almost the same before fruiting as during rapid fruit-body elongation. Specific activities per milligram protein against the three types of nonnative substrates increased in parallel to a maximum late during rapid elongation when protein concentration was lowest. Specific activity against native mycelial protein was also higher in extracts from older mycelia. Proteolysis was optimal near neutral pH and very low at pH 3.2. Tests with group-specific proteinase inhibitors showed that metallo-proteinases predominate in the mycelium. Serine, and to a lesser extent carboxyl and thiol proteinases, were also present. Neither endogenous inhibitors nor activators of proteolysis were detected.
