SPORE MORPHOLOGY OF SOME GRIMMIACEAE ARN. SPECIES BELONGING TO MOSS FLORA OF TURKEY
Abstract:
This study includes spore morphology of seven Grimmiaceae taxa from
Turkey. The spores of Schistidium trichodon (Brid.) Poelt, S. confertum
(Funck) Bruch & Schimp., Grimmia ovalis (Hedw.) Lindb., G. pulvinata
(Hedw.) Sm., G. trichophylla Grev., G. dissimulata E.Maier and G.
decipiens (Schultz) Lindb. were examined by light and scanning electron
microscopy. The apertural region forms from a leptoma in all spores. The
spore morphology of the examined taxa of the family is verrucate type.
The spore shape of all studied species is prolate-spheroid. Spore size
ranges from 6 μm to 17 μm in the family of Grimmiaceae. The spore wall
of the family Grimmiaceae includes sclerine and intine. The examined
species of mosses are belonged to saxicolous habitat type. The
taxonomical and ecological implications of the family Grimmiaceae are
discussed on the basis of their spore morphology.
Key words: Bryophyta, Grimmiaceae, spore morphology, light microscope
(LM), scanning electron microscope (SEM), Turkey.
