These large mushrooms were found earlier in the year (July) in Qualicum on Vancouver Island. They were found growing on the ground in the grass. The cape shape is depressed, with a split cap margin. The cap has appressed scales that are the same colour as the rest of the cap. The partial veil is floccose. The gills are dark brown/black in colour and have an adnate attachment. The gills are also broad, crowded and marginate (have a different colour than the cap). The stem attaches centrally and is club shaped (thicker closer to the bottom). The stem looks fibrous beneath the partial veil tufts. This mushroom is most likely Agaricus augustus, common name the Prince. These mushrooms are super distinct because of their dark gills, and also the sheer size of the mushrooms (up to 30cm across).
