The tapetum disintegrates towards the end of the sporogenesis, leaving spores free within the sporangial cavity. Strobili at different maturation stages were fixed, dehydrated, embedded in resin, and ultra-microtome obtained sections were stained with Toluidine blue.

Therefore, a detailed study of the sporogenesis process and spore development in E. Sporoderm includes three layers external to the cytoplasmic membrane of the spore cell, and they are pseudoendospore, exospore and perispore. Specimens were collected from to m in Cauca, Colombia.
