Observation 137407: Leccinum rugosiceps (Peck) Singer
When: 2013-06-11
No herbarium specimen

Notes: Growing on the ground in mixed woods in the Turkey Creek Unit.
Cap 2.4 cm across and stem 11.8 cm long.
Stem rather scruffy and as Noah suggested, probably in the pseudo-leccimum clade.
Interesting knob on the base of the stipe.
Pores white and no spore print obtained but they appeared to be light colored.
Spores ~ 12.3-15.9 X 4.0-5.0 microns.
L. rugosiceps is still a possibility although the pores are white and the scabers don’t look quite the same(from my limited experience).

for L. rugosiceps can be seen in the oxidation reaction of the exposed pileus context. While the species has been placed in Leccinum by some, molecular phylogenetic inferences reveal a generic distinction elsewhere in the Boletaceae.

Thank you Roy,

I need to stop second guessing myself.

in the sense of L. aurantiacum and L. scabrum. The hymenophore looks yellow in one image.
