Observation 205619: Strobilomyces Berk.
When: 2015-06-02
Herbarium specimen reported

Notes: Cap: 2. inches across. Heavy dark tufts.

Stem: 2.5 inches long. Dark fibrous coating.

Pores: greyish turning dark with dark spore.

Spore Print: Dark grayish black.

Habitat: Growing directly out of a Short-leaf Pine. After discussions with D. Lewis is seems that boletes including S. confusus occasionally grow from the base of tree trunks, apparently the mycellium needs to escape wetness and flooding.

[20/1/1] L (-8.8) 8.9 – 10.0 (-) μm x W (-7.7) 8.0 – 9.0 (-9.1) μm, (L = 9.3 μm, W =8.4 μm), Q (-1.03) 1.06 – 1.15 (-1.24), Q = 1.11 Subglobose

Spore Ornamentation: ornamentation of spines and occasional short ridges; not reticulate

This indicates that it best fits Strobilomyces confusus

ID needs to be changed to S. confusus

I discussed this observation with Dr. D. Lewis who has been collecting mushrooms in SE Texas for many years. He said he has seen this many times, Boletes or other mushrooms growing directly out of trees – including S. confusis. He said he has concluded that the mycelium at times needs to escape very wet conditions and moves a short way up the trunks of trees. That describes conditions all over East Texas this spring and early summer with record rains and flooding.

The only other vote is so high that I can’t overcome it.

Why not confusus?

The spores look right.
