Age of forest did not seem to have affected the timing and sequence of development for archegonia and antheridia so, as was done for sporophytes, data were pooled for each species to better demonstrate any pattern in phenological development.
The data for antheridia did not allow interpretation of a phenological sequence.
The juvenile, immature and mature phenostages of both archegonia and antheridia of Rhynchostegium tenuifolium peaked in summer but dehisced stages peaked in autumn.
Antheridia were noted only in spring but all were at the immature stage.
Thus the evidence is very strong that sexual reproduction occurs in each of the four species examined and does so regularly, although the data for both W extenuata and Rosulabryum billarderii were insufficient to determine the phenological development of antheridia.
Rhaphidorrhynchium amoenum had a greater number of antheridia than archegonia, which offset the greater number of perichaetia than perigonia.
dioicous Having the antheridia and archegonia on different plants.
capsici by producing globose oogonia with paragynous antheridia, chlamydospore, torulose hyphae and lemon shape of sporangia with long pedicels.
Based on morphological characterization, the foot rot pathogen exhibited of globose oogonia with paragynous antheridia, chlamydospore, torulose hyphae and lemon shape of sporangia with long pedicel.
The meristematic region, placed in the midrib of the gametophyte, and the antheridia are regularly free of infection.
muenchii is cordiforme, no archegonia are produced, only antheridia were reported; nevertheless, the sporophyte talus has an apogamic origin (Perez-Garcia et al.
