Hypnum circinale spores (click to enlarge)
Sporophyte samples of Hypnum circinale in which our spores were obtained from.
Hypnum circinale Hook.- Bryopsida
Description of spores: Smooth to lightly papillae, spherical, papillae are irregularly shaped; a lot of spores from one sporangia
Size: Up to 15 μm
Habitat: Found on tree trunks ,decomposing logs and rocks.
Dispersal Mechanism: Hygroscopic endostome teeth flick spores out of the sporangium into turbulent air. Hygroscopic seta provides some movement to the sporangia to shake out the spores and further increase dispersal distance.
Prediction of spore adaptation: The papillose surface allows for a velcro action to stick to substrates. This can secure its place on the substrate and allow it to germinate without any disruption.
