Observation 215905: Boletaceae Chevall.
When: 2015-09-10
Herbarium specimen reported

Notes: I’ve decided the shredded stipe is probably caused by the hot dry conditions. Assuming the stipe is smooth, I have gone through several keys but am unable to get a match.

HABITAT: In grasses,sparse and not, under Oak and Crepe Myrtle.

SIZE: Medium Large Boletaceae

SMELL, TASTE: Insignificant

CHEMICAL:
KOH – turns orange on cap, pink-orange on cap context, dark orange-brown on stipe context.
Ammonia – flash green-blue on cap. Nothing on context of cap or stipe.

STAINING: immediate blue of stipe and pore surface if touched, pores turn dark blue-black when cut, some darkening of cap and stipe context when cut but then fades.

CAP: Largest- 4 inches across. Surface yellow at first, changing to orange-brown with yellow blush – then lightens to reddish tan with age, to touch like suede. Context medium clear yellow. Pore surface yellow turning olive-grey-brown as ages due to spore. Pores yellow, a little darker than cap context. Largest pores about 1 mm diameter. Cap flesh thickness – approx 3 cm at thickest, pore length max – 1.3 cm. see photos.

STIPE: approx 1 inch diameter. Context slightly deeper yellow than cap context. I don’t know how to describe the stipe, see photos. ARE THESE SCABERS? How to describe the stipe surface?

SPORE PRINT: was not able to get a print. From looking at the pores of the largest cap, appears to be dark olive-brown.

SPORE IMAGES, SIZES: Sliced off tips of pores on large cap. In progress.
