The North American Species of Pholiota

dull cinnamon veil distinguish it from P. fulvozonata, P. brunnescens,
and P. highlandensis.
151. Pholiota luteobadia sp. nov.
Pileus 8-20 mm latus, late convexus, glaber, glutinosus, badiorubrus;
contextus luteus; lamellae luteae, angustae, confertae; stipes 1-2.5 cm
longus, 1-1.5 mm crassus, luteus, sutbfibrillosus. Sporae 6-7.5 x 3.8-4.2 JL;
pleurocystidia 48-75 x 10-15.t subacuta; cheilocystidia 33-55 x 8-16.L,
clavata, submucronata vel fusoide ventricosa et ad apicem obtusa. Specimen typicum in Herb. Univ. Mich. conservatum est; legit prope WTilderness Point State Park, Emmet Co., Mich. 24 Sept. 1953. Smith 43222.
Pileus 8-20 mm broad, broadly convex with an inrolled margin,
surface glabrous, slimy, dark bay red over all and remaining this color in
drying. Context yellowish, thin, pliant, odor and taste not recorded.
Lamellae narrow close, adnate, ochre yellow and retaining much of
this color in drying.
Stipe 1-2.5 cm long, 1-1.5 mm thick, equal, yellowish and drying
with a yellow tone, veil rudimentary, stipe surface at maturity merely
with a thin coating of fibrils, darkening only slightly at the base.
Spores 6-7.5 x 3.8-4.2 a/, smooth, apical pore minute; shape in face
view elliptic to narrowly ovate, in profile elliptic to oblong; color in KOH
dark cinnamon, in Melzer's reagent paler; wall about 0.25 p. thick.
Basidia 16-20 x 5-6 pt, yellow in KOH, fading to hyaline, 4-spored,
clavate. Pleurocystidia abundant, 48-64 (75) x 10-15 Lu, fusoid ventricose
with subacute to obtuse apex, rarely branched, walls thin, content homogeneous and yellow to hyaline. Cheilocystidia abundant, 33-55 x 8-16 pL
clavate to utriform or merely fusoid-ventricose.
Gill trama of a central area of parallel non-gelatinous smooth
hyphae yellowish in KOH becoming hyaline, the walls smooth and the
cells not greatly inflated (all young); subhymenium a very narrow subcellar zone of hyphal cells (1-2 deep) possibly subgelatinous (very
slightly refractive in KOH). Pileus cutis a very thick pellicle of gelatinous
ochraceous often incrusted hyphae 2-3 ju diam., loosely interwoven;
hypodermium bright ferruginous, the hyphae heavily incrusted but
hyphae not (yet) greatly enlarged. Context of yellowish then hyaline
thin-walled closely interwoven hyphae. Clamp connections present.
HABIT, HABITAT, AND DISTRIBUTION: Gregarious in a burned area,
Wilderness Park, Mich., Emmet Co., Sept. 24, 1953. Smith 43222, type.
OBSERVATIONS: This is a distinctive species both in the field and in
the herbarium by virtue of the dark red pileus and yellow gills and stipe.
Of the microscopic features the very weak development of a subhymenium
appears significant, but old specimens have not been available for study.
