amirrati is supposed to stain purple, I think. ferrugineus is supposed to be more slender?

So are the characteristics of this specimen

a better fit with Thiers’ description of T. ferrgineus or T. ammiratii?

I wonder

about our coastal Tylopilus – we often call them T. humilis, but look at Thiers’ description here:

“The most unusual feature of this species is the apparent trend toward becoming gastroid. The stipe is frequently poorly developed and eccentric, and the tubes are sometimes permanently covered by the cuticle of the pileus. Furthermore, the basidiocarps often remain below ground until full maturity and some become only partially exposed. However, T. humilis is not a true puffball, since the spores are forcibly discharged.”

This makes me wonder what range of gastroid-ness can be understood for this species. This, for example is a well-formed bolete-type mushroom. In Santa Cruz I find a similar thing that fruits mostly underground, but is still well formed, and Thiers apparently had a misshapen AND underground entity.
