Observation: Xanthoconium affine var. affine (8036)

When: 2008-06-09
Collection location: Big Thicket, Polk Co., Texas, USA [Click for map]
Who: Ron Pastorino (Ronpast)
No herbarium specimen

Notes: This specimen had the general appearance of Gyroporus castaneus but the main characteristic were the yellow spores, ( appeared to be the right size and shape), which eliminates most other possibilities.

Summary: NICE -- that's how it should be done!!

Great job Ron. I’m the bad guy usually, the one who complains that things are not done right, but let there be an exception—this is how it should be done!!

The yellow spores are very telling and a key characteristic that eliminates a tremendous amount of empty speculation.

Summary: Renaming to Xanthoconium affine var. affine

Added photos of spore mass and spores from microscope. I believe that the bright yellow-brown color of the spores and the overall characteristics of the specimen are more of a match for the Xanthoconium affine

Summary: Maybe a Xanthoconium

Thanks Tom. In looking at the spore mass again the more concentrated areas do have a more brownish yellow color. I don’t see a Gyroporus alternative but Xanthoconium affine looks fairly close. The cap and stem coloring seems closer also. I also think the spore size and shape is closer to X. affine. Any other votes?

Summary: different Gyroporus?

Hi Ron, these have a very different coloration and cap shape from what we see up north in Wisconsin. Maybe a differnt Gyroporus species?
