Dyer's Polypore and Zigzag Goldenrod

The mushroom at the base of this white oak tree is a dyer's polypore (Phaeolus schweinitzii).  It popped up to surround the zigzag goldenrod (Solidago flexicaulis) in the middle of the picture. The big dyer's polypore section in the left of the picture is concave enough that it is holding water like a birdbath.  Green algae is growing in the water.  The plant on the right is Lonicera maackii. This white oak tree is in Moyer-Gould Woods in Carroll County, on high ground at the edge of a ravine.  A spring emerges directly below the tree keeping it perpetually watered.  Along with the goldenrod the polypore surrounds a dead stem of Osmorhiza.  Picture taken September 22, 2013.

Bur cucumber tendrils


Tendrils of bur cucumber (Sicyos angulatus) get tightly wound up wherever they touch the plant that the bur cucumber is climbing over.  This bur cucumber is climbing over a sunflower at the north wetland at Celery Bog Park near Cumberland Drive.

These are new bur cucumber tendrils reaching to find a plant.to grab.  If they touch something they will wind up to look like the tendrils in the top picture.
