Specimen notes
Public Note:
Not Betula pendula. Leaves bigger and more like populus. Tree bark like Betula pendula. Stem base not strigose - not thejogalus (altho Bessette's photo also doesn't show this). Milk white turning wartery, not yellow, not changing colour (not vietus). No smell. Taste acrid. KOH on cap no change. Stem not scrobiculate, or sparsely so. Cap surface rugulose when young and becoming coarsely fibrillose with age, sticky when wet (dried leaves stuck to it). Cap edge weakly fibrillose. Cap shape consistently involute. Cap colour orange-buff. What is this? Not L. pubescens - too dark and cap edge insufficiently hairy. Spore print pure white. length=6.6-8.0µm (µ=7.3, σ=0.3), width=4.4-5.6µm (µ=5.0, σ=0.3), Q=1.3-1.6µm (µ=1.5, σ=0.1), n=20. Spores size places this firmly within range of pubescens and not torminosus.
