March
10th. Still at Oconee
Heritage Park (OHP). I found…
these
old brackets on a tree by the trail. I knew, from experience, what they were: Fuscoporia gilva (Mustard Yellow
Polypore), formerly called Phellinus
gilvus. Although these brackets were old, they were quite beautiful.
A
close-up of one of the brackets, and its…
pore
surface. This fungus has very small pores.
F. gilva brackets don’t always look
like the above as as they age.
I
found these older brackets on a fallen log at OHP on the same hike.
I’ve
only found fresh F. gilva with mustard yellow margins on one occasion,
at Fort Yargo State Park, where I found them on a…
fallen
tree trunk.
The
tops of fresh brackets were a deep brown with a mustard yellow margin, hence,
their common name, Mustard Yellow Polypore.
Their
pore surface was also a deep purple-brown, with…
very
fine pores.
The
mustard color faded to brown within a week.
Yet
another cluster of F. gilva, growing
on a tree at the State Botanical Gardens of Georgia, south of Athens, Georgia.
Even
very small, developing brackets lacked the mustard yellow margins. They did,
however, have very small pores characteristic of this species.
In
this area, F. gilva brackets are
usually approximately 2 – 2.5 inches wide, but they can grow up to 6 inches wide. They
may grow as single, or clusters of overlapping brackets.
