When: 2015-08-28
Herbarium specimen reported

Notes: Notes
Entry August 31 Update, collected 3 specimens all immature, white with lavender purple stains at the same spot I found the mature ones,see last photo, I saw no other mature ones, will check back in a week or so and try to collect another mature one to do chemical testings again
Moved to Observation 214970


In grasses, under Oak.
Several white-brown boletes were growing in the grass. When I split them open I discovered it was a mixed collection. This observation is for the two wide boletes, looking like joined twins. They had a white pore surface. White flesh, riddled with worm holes, netted stipe, thin white pore surface. I broke off the cap areas with pores and threw out the buggy remains.

The width of the largest cap was about 2.5 inches across.

I was able to obtain a scant spore print. I saw no color in it. I was able to photograph and measure a few spores.

Measurements of 3 Spores
0 | Length | Width | Q
1 | 9.33 | 5.24 | 1.78
2 | 11.44 | 5.43 | 2.11
3 | 11.35 | 5.00 | 2.27

Chemical Reaction KOH, none , Ammonia, none Correction, I saw red stain bleeding from the pileus, thought this was just pigment bleeding from the dark brown surface. Next time I find them, I will check more carefully.

Many of the photos were of the mixed collection. I’ve marked out the second species, or indicated with arrows the species for this observation.

There are three species in the pix of this observation. The heavily reticulated Boletus s.s., the Leccinum you posted in obs 214837 and the purple-capped entity with a glabrous, whitish stipe (when young) that stains brown when handled, which, I guessed, could be a Tylopilus.

you don’t think these immatures are the same species?? The only way to be sure is for me to monitor some growing over the next week or so and see if they mature into same as the mature ones.

The bolete in the last image…

… is likely to be a Tylopilus, probably T. rubrobrunneus.

The other bolete…

…could be a Leccinum (L. rugosiceps or L. crocipodium).
