When: 2015-03-04
Herbarium specimen reported

Notes: Single Clump of 4 stalks found under old mature Sweet Gum. The area is filled with Water Oak and other hardwoods. Water Oak was also within 4-5 feet. growing out of ground through leaf litter.

Caps – did not open like gilled mushrooms or Boletes. The cap broke open like the cap was a seed pod. White inside. I saw no sticky material but it has been raining very hard all day. The largest cap is about 3/4 inch thick.

Stalk – about 1/2 inch thick, hollow, yellow toward lower half and yellow inside. Outer sheath peeling off. Longest stalk was about 6 inches long.

Microscopy -

Segmented spore pods, some in chains of varying lengths. Maximum length of segment appears to be about 31 microns with a width of about 5 microns.

Looks like the right genus. I am reading other observations and will try to get data needed for species.

I used a garden trowel to dig this up. I didn’t see any tuber but may I didn’t go deep enough.
