Again a mushroom with fantasy name. It refers to the somewhat yellowish stem of the fruitbodies. This mushroom has a slender stem and a golden brown cap. The gills are protected by a veil which becomes a ring around the stem after the cap opens. The mycelium is somewhat less vigorous than the PF genotype, but still appears within a week after inoculation. The spores of this genotype do ripen unusually fast. It is possible to inject a just-not opened cap with some sterile water, then soak it back into the syringe and use that for the inoculation of a new jar. Also the mushrooms are somewhat more forgiving than the fruitbodies of the PF genotype. They sporulate heavily in environments of 85 percent relative humidity and even lower. These qualities make this genotype especially suited for starting mycophiles who wish to make their own inoculants immediately.
