There might be some confusion between the namings P. papilionaceus var. papilionaceus and P. papilionaceus var. parvisporus. I believe this is var. papilionaceus, as it appears that var. papilionaceus tends to have a shiny, smooth skin, where as pictures I’ve seen of var. parvisporus appear to have a matted, lackluster skin. I went with MO’s suggestion to eliminate the variety from the latin name because MO mentioned those variety names are deprecated. Any comments would help.
