Macro: Collected example of gilled mushrooms on the Coastal Bend College campus at Beeville, Texas. The location was a pond along the hiking trail behind the main campus. Beeville is experiencing drought conditions and the pond is and has been dry, for months. A group of eight basidiocarps was scattered underneath the branches of a Black Willow tree (Salix nigra) but located in dense turf on the sloping bank on the dry pond and these were collected. They all appeared to be mature and most of the spores were gone. Cap shape was convex and of tan to brown color. Cap margins were smooth. Cap diameters were between 2cm to 3cm without tackiness and there was no evidence of latex. Stipes were approximately 3cm long and 5mm in diameter. The gill attachment was strongly decurrent. On the initial posting of these specimens on Mushroom Observer, one member suggested that the genus was Inocybe.
Micro: I was unable to retrieve a representative number of spores from the samples. There were so few that I fear the one I did examine under the microscope could have been associated with some other fungus. If the spores were from my specimens and not some contamination, one of them (see photo) was oval without armor and measured 5µm x 4.2µm (smaller than would be expected for Inocybe)
