Spore of Helminthostachys zeylanica from Yunnan and Hannan of China and Japan was examined by SEM and TEM. Their spore morphology is same. The spores are globose, trilete, with crassus exospore and thin perispore. The surface ornamentation of spore is coarse, prominent, more or less fused baculate with delicate projections.
