Conservation Status: Not of concern

The name Hygrophorus olivaceoalbus has been applied differently by various mycologists both in Europe and North America. However, typically it is considered a fungus with a streaky, olivaceous brown or grayish brown, viscid cap (darkest in the center), white clean-looking gills, long white stipe with bands of grayish brown fibrils overlaid by a slime layer below the ring-zone, large ellipsoid spores (10--15 x 6.5--9 µm), and association with spruce. When fresh, it is a most attractive fungus. H. persoonii Arnolds is a very similar species that associates with broad-leaved trees in Europe; it has been reported from California, but under spruce. A smaller species with dry stipe, H. inocybiformis A. H. Smith, is fairly common in Idaho and the Rockies.
