Abstract
In Stereocaulon nesaeum Nyl. ascogonia are first found in young apothecial primordia that do not differ macroscopically from other terminal phyllocladia. Numerous ascogonia develop as the primordia expand and deep-staining connecting hyphae uniting adjacent ascogonia have been observed. Each ascogonium develops a trichogyne which may project a considerable distance into the air. Spermogonia containing free spermatia are formed near apothecial initials bearing trichogynes. These observations suggest that spermatia have a sexual function in this species.This publication has 4 references indexed in Scilit:
