Specimen notes
Public Note:
small xerocomus, flesh white, pores yellow, all blueing rapidly. Spores 13um x 5um, Q=2.6, ammonia reaction negative (to answer question posed in McNabb's paper). Stem base without rhizoids. My collections have spores consistently larger than that reported by McNabb. length=10.5–12.9µm (µ=11.9, σ=0.66), width=4.0–5.4µm (µ=4.7, σ=0.38), Q=2.1–3.1µm (µ=2.55, σ=0.27), n=20. ITS makes this slighlty different to other X. squamulosus, perhaps X. scabripes? LSU the same. McNabb says "Xerocomus scabripes resembles X. squamulosus McNabb in general appearance, but may be distinguished by the smaller pores, dark brownscabrous stipe, and narrower spores" He has X scabripes with spores 9.4-13 X 3.2-4.5 um, occasionally to 18 X 5 um but then misshapen. X. squamulosus 9.6-11.7(13.4) X 3.9-5 um. The spore variation is greater than McNabb's difference.
