sporangia are found at the tips of sporangiophores that emerge through the stomates. Sporangia release zoospores which require water for transport. Zoospores...

the roots may be facilitated by "air-borne propagules entering through stomates". In the same study, Sphaerosporella ascocarps were more often observed...
