Chlorophyllum olivieri
Common: Shaggy Parasol
Description: Cap: 5-12 cm wide, convex becoming flat with a knob in age; grayish olive brown, smooth; margin like the disc at first, soon breaking up concentrically into coarsely fibrous scales on a dingy background. Gills: free, white, becoming red or brown when bruised, darkening in age, close, edges finely fringed, in two or three tiers. Stalk: 7-15 cm long, about 1 1/2 times as long as the diameter of the cap, top 7-15 mm thick, equal with an abrupt rounded bulb at the base, smooth, white, surface darkening when bruised, cut flesh staining reddish or saffron. Ring: thick, persistent, membranous, double, the edge fibrous and frayed, white with the lower surface darkening in age; movable like a ring on a finger. Odor and Taste: not remarkable. Spore print: white.
Habitat: litter under conifer or deciduous trees; scattered to gregarious.
Primary keys: large dingy soft cap with darker scales, gills white darkening with age, stalk ~1.5 times as long as cap diameter, staining red-orange, double ring, bulbous base, spore print white
Edibility: edible and choice, but of the gilled Chlorophyllum species in the Northwest, one or more sicken some people; it is uncertain which because in the past all three were called "Macrolepiota rachodes". Try a sampler first whenever gathering these from a new area.
Notes: This mushroom was first Lepiota rachodes, then Macrolepiota rachodes, now it's split into 3 different species of Chlorophyllum. Please see What's Become of Macrolepiota Rachodes? for details. C. molybdites is a very similar, light-green spored species that causes many extremely unpleasant, but non-lethal poisonings in warmer climates. So far the green-spored shaggy parasol has not been reported in the PNW, but be very careful collecting shaggy parasols in warmer areas.

12 Chlorophyllum olivieri "marshmallow" caps
3 strips bacon, fried crispy, drained and crumbled
6 T. frozen petite peas, thawed and drained
2 T. butter

Preheat oven to 350 deg. Break stalk out from shaggy parasol and clean caps. Saute shallot in butter over medium heat until translucent, then add flour and saute for 2 minutes. Gradually add milk, stirring constantly until sauce thickens. Add nutmeg, salt and pepper. Add Gruyere and 1/2 the Parmesan, stirring constantly until cheese is melted. Remove from heat and add bacon and peas. Coat the cups of a muffin pan with cooking spray. Spoon the filling evenly into the mushroom caps.
