the specimen got tossed after last night’s BAMS meeting.
Found in mixed forest, primarily hardwoods. I’m gonna stick with chrysenteron for now, altho your objections are noted. Yellow mycelia at base suggests trucatus, little blueing suggests chrysenteron; only the spore shape knows for sure.
Under Live Oak, I tend to find X. truncatus a lot more often than X. chrysenteron. The opposite is true on the Peninsula, where chrysenteron predominates in the Redwood, Douglas Fir, Tanoak habitat. I have no reliable means to tell them apart (yet). The bluing reactions or lack of and pink epithelium are not reliable characters at all.
The only reliable character are the distinctly truncated spores of truncatus…
Wish you got a better photo of the pores here. There are red-pored forms of this one around the bay area, and they seem to exist more when the cap is really-really cracked like this one. Although the red-pored form seems to appear rarely and randomly, so it might be good to get more photos of pores on these.
