Sporangium

There are a few sporangia on the sample slide. The sporangia seem like spores are surrounding apophysis.

Image	Data	Description
	200x	The spores are surrounding entire surface of the apophysis. There is a torn-off area where connection of the spores seems to be broken.
	200x	Most part of the surface of this apophysis are revealed, because there are only a few spores left on the apophysis.

Columella

Columella is a circular shaped and appears as brown and red. Some columella looks like a mushroom. The spores don't cover the surface of columella. All columella is connected to stolon, a brownish tubular fiber. Some columella's surfaces seem to be smooth, while other columella's surface are rough. An area where the columella and the stolon are connected to each other is called apophysis.

Image	Data	Description
	200x	Here is a mushroom-like columella. As shown in this picture, the columella is connected to the stolon.
	400x	The surface of this columella appears to be very smooth, and it is slightly transparent.
	200x	A reddish columella mostly has rough texture. The shape of this columella looks like a military cap.
	400x	Apophysis, an area where the columella and stolon meet together, seems to be transparent. Still, the surface of the columella appears to be rough.

Stolon and Sporangiophore

Image	Data	Description
	200x	Brown branch-like fibers are called stolon. The stolon connects to the columella. Reddish fibers on the image are sporangiophores, fibers that attach columellas.

Sporangiospores

Image	Data	Description
	1000x	Spores are about a size of animal cell. The shape of the spores are also similar to that of animal cell. The texture of the spores seems to be rough.
