Species Information

Summary:
diagnostic characters are small to medium size, flat to flat-convex cap when mature, dull white bald cap, white stem, pleurocystidia of cervinus type, and pileipellis without clamp connections, (Banerjee(3)), other features shared by most Pluteus species include free close to crowded gills, pinkish spore deposit, and growth on wood, in this case hardwood; Justo(1) separated Pluteus nothopellitus Justo & M.L. Castro sp. nov. (without clamps and with large spores (6.0)6.5-9.0(9.5) x 4.5-6.5(7.0) um) from Pluteus pellitus (Pers.: Fr.) P. Kumm. (with clamps and with smaller spores 5.5-7.5(8.0) x 3.8-5.3(5.5) um); description derived from Banerjee(3) below would fit Pluteus nothopellitus, but specific data from Pacific Northwest specimens are required; Banerjee(3) examined collections from WA, ON, IL, KY, MI, OH; Paul Kroeger deposited collections from BC at University of British Columbia
Cap:
3-5(8)cm across, obtuse when young, expanding to convex or flat-umbonate or with a shallow depression; evenly dull white and changing to 'yellowish-white' when old; moist but not hygrophanous, bald, somewhat radially fibrillose
Flesh:
moderately thick and cottony; white
Gills:
remote from stem when old, close to crowded, broad, 1-2 tiers of subgills; white, becoming pink, edges whitish; edges slightly fimbriate [fringed]
Stem:
4-10cm x 0.4-0.8cm, "equal or evenly enlarged", "sometimes with a broadened bulbous base", firm; white throughout and not changing appreciably; bald in upper part but somewhat fibrillose in lower part, squamose [scaly] around base, lacking persistent mycelium at stem base
Odor:
fungoid
Taste:
mild radish-like
Microscopic spores:
spores 6.8-7.8(9) x (4.6)5.4-6 microns, broadly elliptic to oval-elliptic, smooth, colorless, wall thin to only slightly thickened, hilar appendix inconspicuous; basidia 4-spored, occasionally 2-spored, 16-22 x 6-7.4(9) microns, colorless; pleurocystidia vary abundant, (34)55-80(90) x 9-16 microns, fusoid-ventricose to broadly cylindric with an obtuse or occasionally truncate apex, few of magnus-type [fusoid-ventricose, gradually tapering to an acute or rarely forked apex], all colorless, irregularly thick-walled (1.8-2 microns at apex), "with 2-5 (mostly 2) short and blunt hooks at or near the apex", cheilocystidia 28-34 x 8-14 microns, spheropedunculate, rarely some similar to pleurocystidia but with thin walls; cap cuticle of appressed radial hyphae, "occasionally with a loosely formed ixotrichoderm", terminal members 50-125 x 4-7.4(10) microns, apices rounded, colorless; clamp connections none on cap cuticle hyphae
Spore deposit:
pink (Buczacki)
