I need to check my yard more often. Found about 6 stinkhorn mushrooms in the yard, a bit past their prime. Could use some confirming the ID. Seems to be a good match based on pictures and description in the Metzler's Texas Mushrooms book. Update: Went out in the yard again April 13 and several more had come up or were just about to come up. There were at least 20 including the ones previously seen.
