I am amazed that the web seems devoid of cross sections of Receptacles of the Fucoids. I will attempt to put this right.
The first then shows the lovely swelling eggs of Egg or Knotted Wrack. This has bladders singly along the mid stem and cannot easily be confused with Bladder Wrack (often paired or multiple bladders).. The Receptacles, holding the fertile Conceptacles, are actually quite similar in appearance to the Spiral Wrack ones. In due course, I will display both side by side and more Fucus Receptacles.
The air bladders are empty with leathery shells but the eggs, on quite long oval stalks, have smooth rims (Picture 6). The 'eggs' are nearly transparent at the fairly early stage from mid March and eventually become very jelly filled and the warts (Conceptacles) burst when handling and actually stain the hands.
