Mushroom Log - early September 2014

Bleeding Mycena - Mycena haematopus
Named the Bleeding Mycena because it exudes a reddish juice when crushed.  Presented here at three stages: above, in middle-age.
Young and fresh.
Way old.

Fused Marasmius - Marasmius cohaerens

Some features I found helpful in separating this mushroom from other LBMs:
  • flat to slight bell-shaped (umbonate) cap.
  • growing in clumps in the on the ground in mixed woods.
  • a stem that starts out light brown at the top, fades to reddish in the middle, and finally to a dark brown at the bottom.
  • dense mycelium at the base of the stem, forming sort of a pad.
  • Under a microscope, the gill tissue sported prominent spike-shaped structures known as cystidia. Cystidia are non-spore producing cells found on the gills of many species of mushrooms.  They come in variety of shapes and can be useful in identification.  Their function is unknown.  My microscopy skills are still quite rudimentary, but these things really stood out.
Clitocybe candicans

Unknown mushroom

Psathyrella sp?
The black spore print and two-tone cap points towards these little mushrooms being members of the genus Psathyrella.  They were growing on a recently wood chipped trail.

Fiber Head - Inocybe sp.

Unknown Amanita - Amanita sp.
