1 In the first example (in cell C1), the value argument, A1/B1 returns the value 0.5. This is not an error and so this value is returned by the Iferror function.  In the second example (in cell C2), the value argument, A2/B2 returns the DIV/0! error.
One of the best mushrooms for color is Phaeolus schweinitzii, the dyerâs polypore. The best time to pick and dry this mushroom is when the outer growing edge is bright yellow, with yellow-green pores underneath. When cooked with alum-mordanted wool and a 1:1 ratio, the color will be a bright yellow or gold.
Last year's reishi mushrooms are no longer of any use medicinally, but they're still eye-catching. For medicine, it is most efficient and ethical to harvest relatively mature conks. The white growing tip should be very thin or gone, and the overall color gradient should fade to a deeper, but still vivid, red.
