Description: Mushrooms hemispheric to plane, sometimes umbelicate, uniformly tan, beige, grayish brown, to gray in color, sometimes with faint streaks, and measuring 4-15 cm. Cap margin
inrolled to incurved when young, expanding with age, even to slightly undulating. Gills decurrent,
close, often running down the stem. Stem eccentrically attached, thick, tapering and curved at the
base. Usually found singly, sometimes in groups of two or three, rarely more.
Distribution: Throughout the temperate forests of eastern North America, Europe, and Japan. Probably widespread throughout similar climatic zones of the world.

Natural Habitat: A saprophyte on elms, cottonwoods, beech, maple, willow, oak and occasionally
on other hardwoods.
Microscopic Features: Spores white, spherical to egg-shaped, 3-5 i. Clamp connections numerous.
Hyphal system monomitic.
Available Strains: Strains are available from Japanese, American & Canadian culture libraries. The
strain featured in this book originated from Agriculture Canada's Culture Collection, denoted as
DAOM #189249, produces comparatively large fruitbodies. (See Figure 228). Patents have been
awarded, both in Japan and in the United States, to a Japanese group for a particular strain of H.
ulmarius, which produces a "convex cap".* (See Kawaano, et al., 1990.) The method of cultivation

A mushroom strain producing a convex cap is hardly unusual, let alone patentable. During their life cycle, most gilled
mushrooms progress from a hemispheric cap, to one that is convex, and eventually to one that is plane with age.
