|The aethelium (combined spore-bearing structure) of Mucilago crustacea on the stem of a reed at Winnall Moors, southern England.|
|The cortex in close-up showing the spongy, almost brain-like, texture and powdery surface.|
|A mass of spores and calcareous crystals under x40 magnification. The dark circles are air bubbles, but note the scattered spores which appear as tiny brownish circles in transmitted light.|
|One of the masses under x100 magnification. A cluster of brownish spores can be seen bottom right, each being a little over 10µm in diameter. The calcareous crystals are a similar size and can be seen as small spikes to the left of the picture. |
