| intro |
Olive text indicates a specimen that has not been
thoroughly examined (for example, for microscopic details) and marks other places in the text
where data is missing or uncertain.
The following material is based on original research of R. E. Tulloss. |
| pileus |
33 - 46 mm wide, white to pale yellow (near 3A2 or near 2.5Y 8/2) over marginal striations, with disc orange-tan (about 5B5) or yellow-brown (10YR 6/6 or slightly more orange than 10YR 6/6), partially bleaching or becoming uniformly pale cream in age, convex to plano-convex, often with decurved margin, finally concave with up-flaring margin at maturity, tacky to viscid at first, subshiny when dry; context whitish with yellowish/tannish region in disc to mostly yellow with white only near lamellae, unchanging when cut or bruised, 1 - 4 mm thick, thinning evenly for 50% to 80% of radius, then membranous to margin; margin short-striate to striate to tuberculate-striate (0.25 - 0.6R), nonappendiculate; universal veil absent or in irregular small warts crumb-like, sometimes crowded over disc, cream to pale tan, pulverulent to floccose, detersile. |

| lamellae |
narrowly adnate to free with or without decurrent lines on stipe apex, close to crowded, off-white to cream in mass, white or watersoaked in side view, 2.5 - 6 mm broad, somewhat tear-shaped to ventricose; lamellulae truncate to rounded truncate to truncate with attenuate tooth near pileus context, of diverse lengths, unevenly distributed, relatively common. |
| stipe |
28 - 80 × 3.5 - 6 mm; white, sometimes with yellow tint near apex, browning somewhat from handling, narrowing upward to subcylindric and flaring slowly toward apex or narrowest at mid-stipe, often somewhat flattened in upper portion (take cross-section at apex), occasionally somewhat flexuous, satiny to finely pulverulent above annulus, sometimes somewhat shiny and minutely fibrillose and longitudinally striatulate below annulus; bulb 6 - 15 × 5.5 - 15 mm, subglobose to ovoid to subnapiform to somewhat irregular (knobby) and then with somewhat rounded point on bottom; context white to off-white, unchanging when cut or bruised, hollow to stuffed with white material, with central cylinder 1 - 1.5 mm wide, concolorous to faintly tannish in larva tunnels; partial veil median to submedian, white, membranous, delicate, fragile, flaring upward at first, often lost; universal veil as white role of tissue close to stipe base at apex of bulb or (occasionally) lacking. |
| odor/taste |
Odor fungoid or lacking. Taste not recorded. |
macrochemical
tests |
Spot test for laccase (syringaldazine) - negative. Spot test for tyrosinase (paracresol) - positive throughout basidiocarp in 1 min., with gill faces last to show strong positive. Test vouchers: Tulloss 8-23-85-B, 9-1-85-H, -I, and 7-3-87-C. |
| basidiospores |
[60/3/3] (8.2-) 8.5 - 10.4 (-10.8) × (6.3-) 6.5 - 7.5 (-8.6) µm, (L = 9.0 - 9.7 µm; L’ = 9.4 µm; W = 6.9 - 7.0 µm; W’ = 7.0 µm; Q = (1.19-) 1.22 - 1.48 (-1.55); Q = 1.29 - 1.40; Q’ = 1.36), hyaline, colorless, thin-walled, smooth, inamyloid, broadly ellipsoid to ellipsoid, sometimes adaxially flattened, more rarely expanded at one end; apiculus sublateral, truncate-conic to subcylindric; contents mono- or multiguttulate; white in deposit. |
| ecology |
Solitary to subgregarious. New Jersey: At 40 - 55
m elev. In a sandy clay
road bank after heavy rain, subgregarious, in mixed
deciduous woods including Fagus grandifolia,
Prunus pennsylvanica, Betula sp.,
Sassafras albidum, and Quercus spp. or
under Carpinus caroliniana near swampy area
with Acer rubrum, Liquidambar
styraciflua, S. albidum, and other
nonectotrophs or under Q. palustris in
lawn with A. rubrum, Cornus florida, and
L. styraciflua the nearest other trees or
under Q. palustris in lawn with Pinus
sylvestris? nearby or under
Picea pungens (alien) in lawn with no other
ectomycorrhizal plants nearby.
New York: With Tsuga canadensis and Fagus
grandifolia.
Pennsylvania: In lawn under “scarlet
oak.” |
