August-September. Heimioporus betula, the Shaggy Stalked Bolete, is
probably
the easiest bolete to
identify along the trail from the beach to the Old Fort in Fort Yargo State Park.
The dead give-away to
identifying this species is the coarsely reticulated stalk. This photo shows
a particularly pristine stem that becomes more 'shaggy' with age. The red color under the surface is also
characteristic for this species.
Young specimens
growing have caps barely wider than the stalk. When in deep shade their caps
are deep orange. Specimens growing in open woods have a lighter orange-colored
cap. In either case, the caps of young specimens are sticky. The caps usually
enlarge to be wider than the stalk.
As they age, the
caps become dry and start to lose their deeper orange color.
Ultimately, the
caps become yellow-colored.
The pore surfaces
of young caps are irregular with large angular pores, 1-2/mm.The pore surfaces don't bruise blue when damaged.
The pores become
ragged as they age and discolored by olive to olive-brown spores.
The red color under
the surface results from a ring of color immediately under the surface, that...
diffuses
throughout the stalk with age.
Shaggy stalked
boletes may be solitary or scattered over a small area. It was unusual to find…
this pair growing
closely together.
So far, I’ve only
found most specimens in wooded areas between the beach and the Fishing Area.
This year, I did find two small specimens just north of the Fishing Area, away form the
main trail.
Heimioporus betula has been reported only in North
America.
