* Spatoglossum latum J. Tanaka, 1992

Japanese name: ヒロハコモングサ (hirohakomongusa)

Type locality: —Shimoda, Shizuoka, Japan

Description and remarks: —The thalli are upright, 9–15 cm tall, and attached to the rocky substrate using fine rhizoids. The when fresh, samples are light brown in color but turn darker when dried. The distal parts of the fronds are dichotomously branched, broad and appear to be round to obtuse but the ones found in the specimens examined here are torn or bear bite marks from herbivory. Figures 1 –5 in ( Tanaka 1992) shows a good representation of this species and their features. Sori can be seen as black spots scattered across the thallus. This species was common in Yokoura and in Aokata in late spring to early summer.

Materials examined: —18ECS1-19-1 and 18ECS1-32 (1 to 5)
