Smith ~ Hesler

369

cystidia 28-47 x 9-14 u, subfusoid to utriform or clavate, smooth, thinwalled. Caulocystidia numerous over apex of stipe, in rosettes, versiform,
fusoid, clavate, vesiculose, or ventricose above and below a median constriction, pedicel often greatly elongated, apex in any of above types may
be drawn into a filamentous crooked prolongation 3-6 /z diam., walls
thin smooth and hyaline or some of the vesicular elements golden yellow.
Gill trama with a distinct gelatinous subhymenium and a floccose
central strand of subparallel hyphae 4-8 /x broad, and walls hyaline to
pale tawny in color. Pileus cutis a gelatinous pellicle of narrow (2-5 p/)
ochraceous smooth to encrusted hyphae, hypodermium of rusty brown
floccose hyphae. Clamp connections present. All hyphae inamyloid.
HABIT, HABITAT, AND DISTRIBUTION: Scattered on debris, among fallen
aspen, Michigan, September; Smith 66386, type.
OBSERVATIONS: The pale, although rather bright, buff to cream-color
margin and the tawny disc make it a striking agaric. The flesh, gills, and
stipe are likewise pale, and the veil white. In addition, the stipe base is
also pallid, but becomes dull rusty from handling. The caulocystidia are
in rosettes and are rather striking in form.
Stirps Lenta
Terrestrial species or basidiocarps appearing to be terrestrial (not
located directly on wood such as logs, stumps, or branch material above
ground): spores 4-5 / wide; colors various but not as in stirpes Lubrica,
Fibrillosipes, or Polychroa.
