About 8

'''Hygrophorus olivaceoalbus belongs to a group of fascinating waxy caps that feature not one but two veils protecting the young gills. The "inner veil" is composed of tiny threadlike fibers, and the "outer veil" is composed of thick slime. When the mushroom approaches maturity the cap expands to break the veils, which then are left to form a sheath around the stem.

In Hygrophorus olivaceoalbus the inner veil is brown to grayish brown, and easily seen. As the stem grows, the veil is pulled apart, resulting in stretched-looking concentric bands and, often, a thin and flimsy ring. The outer slime veil quickly dries out in warm conditions.'''
