Prairie RosinweedWhite-pored Chicken of the Woods, Laetiporus cincinnatus (the official fungus of Cincinnati) typically appears before its yellow pored cousin, Laetiporus sulphureus. Another difference is that white-pored chicken of the woods typically grows from stumps or buried wood, whereas L. sulphureus more often grows from logs. (Also, it’s not really the official fungus of Cincinnati, at least that I know of). Smooth Sumac in a sunfleck.
