Each summer there are multipe frutings of this very bitter Tylo. For some time I had gone back-and-forth between the names rubrobrunneus and violatinctus. Young material has generally exhibited traits consistent with rubrobrunneus... deep purple cap, glabrous brownish stipe with marbled appearance, the occasional specimen with stipe apex reticulate. But KOH reaction were often much different than what is reported for rubrobrunneus.
