Introduction

Phlebia uda was

When fresh, Phlebia uda can be identified in the field by its waxy consistency (use a handlens), its yellow toothed hymenium, and the bright purple reaction to potassium hydroxide. Under the microscope, the yellow resinous content (visible in water, dissolving in KOH) and basidiospore sizes will clinch your ID.

Phlebia is a genus in the order Polyporales, although few of the species in the group are actually poroid. Mycologists first applied the name to resupinate fungi with a distinctly wrinkled or veined hymenium (like Phlebia radiata), but over the centuries mycologists have broadened the generic concept to include smooth, tuberculate, and also toothed crusts. There is a Many of these species share has been broadened over the years to encompass fairly well characterized genus due to the sustained attention given to it by amazing corticiologists such as Karen Nakasone.
