Small cap in the trail grass
Boletaceae (cf. Suillus) Family
Angles captured. Two field frames, one taken in the photographer's own shadow to cut the glare, plus five of the spore print.
Morphology
Cap 4–6 cm, olive-yellow and irregularly lumpy above, with a dark brown pore surface beneath. Flesh yellow where broken.
Habitat & substrate
Grass and sand at the trail edge, pine nearby.
Lookalikes & what rules them out
The spore print is large and mid-brown, consistent with the pore surface. An olive-yellow cap over dark brown pores with yellow flesh is a narrower combination than most on this walk.
To confirm this identification
Whether the yellow flesh blues on cutting.
Notes
Spore print taken (card 4). A different mushroom from the abundant red-capped species it was photographed beside, despite the two being confused at first. This one was also common along the trail. Corrected. Titled an agaric while the entry itself records a dark pore surface and a mid-brown print. Pores plus print make this a bolete; olive-yellow lumpy caps in grass under pine put Suillus first in line.
