Thanks, Rod, for questioning this. In looking through past notes I find that the two other times I’ve found this species it has, indeed, had flesh that turns red when cut or bruised. Mykoweb’s description seems to indicate that it’s a variable characteristic. MushroomExpert definitely counts the reddening as necessary to identification. My notes specify that there was no reddening when cut on this specimen. Which leaves me still uncertain of the id, but leaning toward the belief that I got it wrong. Help?
One character mentioned in the description of S. cepa is red-wine staining of the underside of the basidiome when rubbed with one’s thumb. I believe I first got this character as a useful diagnostic tool from W. C. Coker’s book on “gasteromycetes” that was republished by Dover Books some time back. This character is successfully observable in fresh material in the central Atlantic states (at least). (Oh, I guess any finger will do.)
Can anyone update me on whether Coker (I’m dependent on my fading memory here) had it correct?
A very nice drawing there. Hardly anyone bothers to do anything
but take pictures of fungi anymore (myself included!).
