“Reticulated” Leccinums

Sure, so do other Leccinum species: Obs. #26487.

Are you sure the photo attached to your comment is that of L. albellum? The pore surface and stipe have stains, and the stature is rather robust for the slender and graceful L. albellum.

Martin’s specimen is also oversized to qualify for any variety of L. albellum.

gets a pseudo-reticulation, esp in age.

Viewing the first picture in the “full size” mode revealed miniscule scaber-like structures within the reticulation mesh and perhaps even covering the reticualtion itself, giving the dark ridges a fuzzy appearance. Also, the reticulation disappears at the lower portion of the stipe, wherein the texture can be visually described as scabrous-fibrillose (it’s certaily not glabrous). So this might be a Leccinum species after all…

I am yet to find a full description and pics of this mushroom online. According to Smith & Thiers (page 214; http://quod.lib.umich.edu/...), only the pileus has a “alveolate-reticulate” appearance — hence the stipe of this species is presumed to be the same as in the generic L. albellum, i.e. finely scabrous and NOT reticulate. Martin’s specimen has a distinctly reticulate pattern.

Also, according to MushroomExpert.com (http://www.mushroomexpert.com/leccinum_albellum.html), both of Singer’s varieties are synonymous with L. albellum, and no specific references are made to the subspecies of Singer therein.

here on M.O. Unfortunately, I did not slice or perform macro chemical tests on this one. No more info is available. Thanks Noah and IG.

Recently I’ve misidentified a couple of boletes on MO (probably due to the seasonal allergies driving me insane), so I am glad I got this easy one right. ;-)

Thanks I.G.

I was just checking to see if you were paying attention! The reticulation is a dead give away that this cannot be Leccinum. With nearly 3000 photos in the last 30 days, I may be moving too fast. Thanks again.
