Abstract | A new species of Annulatascus, A. aquaticus, is described from freshwater habitats in Hong Kong and is illustrated at the light microscope and scanning and transmission electron microscope levels. It differs from other species in the genus as its ascospores are aseptate, ellipsoidal with acute ends, thin-walled, and contain large lipid globules at maturity. Its asci have a bilamellate ascus wall and bipartite apical ring. The upper part of the apical ring differentiates from the inner ascus wall layer, and the lower part elongates downwards during maturation. Ascospore walls are bilamellate, with an electron-transparent mesosporium and an electron-dense episporium. |
