This was my first time ever finding B. gertrudiae, if that’s indeed what it is. Not surprisingly, I initially misidentified it as B. nobilis, which I am more familiar with. My mistake became apparent upon conducting macrochemical tests — the pore surface immediately turned pinkish-red with ammonia, and the exposed context did not react with KOH the way one would expect from B. nobilis.
