When: 2015-05-19

Collection location: Lear Park, Longview, Texas, USA [Click for map]

Who: L G Price (LG_Price)

No specimen available

UPDATE: I went back. 48 hours later, they are all gone. Hard to believe. They were not fragile. Maybe something ate them.

Growing attached to Oak Leaf litter.

These are tough little mushrooms, thin cap but not fragile.

Cap – Funnel Shaped – 1.25 cm, thin, Top med – drk brown, thin cap.

Gills – attached, white. Open spaced, shorter gills interspaced.

Stalk – 3.5 – 4.0 cm long. 1 mm thick, pliable but tough, strong, hard to pull apart. Attached to Oak Leaves with orange and white mycellium.

I am trying to get a spore print but so far nothing.

I’ve lived most of my life where no one expected me to be attached to a cell phone. I still can’t quite get the hang of it! Although I love my computer, I fully remember pre-digital.

It is raining today, but once it dries out again, I plan to go and try and collect a good number of them and photograph them at different stages. With some luck I may be able to get a spore print.

If I succeed, I will add more photos to this observation with an update.

That image was scanned from a Kodachrome taken in the late 1970’s when digital was something you did with fingers and toes. Look at other Observations for the taxon on MO.

Gymnopus biformis – macro image

These certainly look different than the macro image in the reference. The description says convex becoming plane to depressed.

I saw none that had a shape other than what is in the photos for this observation.

Other aspects match.

Thanks for the Gymnopus biformis (Peck) ID and reference.

This keys out to Xeromphalina when I go through the Mushroom Expert Keys.

If you feel so strongly that it isn’t Xeromphalina, a comment as to why it is excluded would be appreciated.
