porphyrosporus is a sombre bolete and not easy to spot, despite its
large size. This summer and autumn species occurs under pines.
Identification guide |
Cap
|
This sombre mushroom has a dark brown cap with
a noticeably paler margin. Initially convex, caps expand and sometimes
become irregularly lobed.
6 to 15 cm in diameter when fully expanded, the caps have soft buff flesh with a vinaceous tinge. |
Tubes and Pores
|
The tubes and pores are greyish-yellow at
first (as in the youngish specimen shown here) but, as the fruiting body begins releasing spores, the pores turn
brown.
When cut or bruised, the tubes turn blue-green. |
Stipe
|
1 to 3 cm in diameter and 5 to 12 cm tall, the stems of this species are
tobacco brown and slightly velvety to the touch when young, becoming smooth
as the fruiting body matures.
The stem flesh is buff, turning slightly blue-green near the apex when cut.
