Observation 110269: Leccinum Gray
When: 2012-09-16
No herbarium specimen

Notes: Pores on this mature mushroom are smaller than for T. sordidus. Also, the staining reaction, although similar to what I have seen for T. sordidus… some blue, some red, is not as pronounced as for T. sordidus. Color scheme of this mushroom, and the Leccinum-like stipe point toward T. pseudoscaber.

Mixed woods with birch, beech, hemlock, and others. No oak.

lead one to L. snellii, red in upper context, blue in lower. But the aerolate cap surface and color of the pores/tubes did not remind me of Leccinum. However, like you say, Noah, this may be a very old fruit body, and characters often morph into anomalies when a mushroom persists through an extended period of very dry weather like we’ve had here for the past two weeks. There were certainly lots of L. snellii in the vicinity of the mushroom seen in this obs.

I am still a bit intrigued by this mushroom. The overall aspect brings to my mind the dark Tylos, T. sordidus, T. porphyrosporus, T. pseudoscaber. And, there seems to somewhat of a lack of closure regarding the use of these species names. The most current photos of T. pseudoscaber do show an overall darker mushroom than this one.
