Bryoria hengduanensis is a species of lichen of the genus Bryoria. It was described as new to science in 2003 by lichenologists Li-Song Wang and Hiroshi Harada. It is found in the Hengduan Mountains of southern China, where it grows on twigs and branches in coniferous forests at elevations of 3,000–4,000 metres (9,800–13,100 ft). The Hengduan Mountains is a region of high Bryoria biodiversity, as 24 species are known from this area. The lichen is fruticose, hair-like, hanging (pendent) from its substratum, and typically reaches lengths of 3–5 cm (1.2–2.0 in) long, although specimens up to 15

Verrucaria yoshimurae is a species of saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae. Found in Japan, it was formally described as a new species in 2011 by lichenologist Hiroshi Harada. This freshwater lichen has a relatively pale thallus. The species epithet honours Japanese botanist and lichenologist Isao Yoshimura.

Verrucaria takagoensis is a species of saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae. Found in semi-freshwater habitats in Chiba Prefecture, central Japan, it was formally described as a new species in 2001 by lichenologist Hiroshi Harada. The lichen has almost spherical, exposed black perithecia measuring 0.1–0.2 mm in diameter, with brownish-black perithecial walls, and lacking a distinct involucrellum. The periphyses are 5–10 μm long with pointed apices, while its ascospores measure 6–8 by 4–5 μm. Verrucaria takagoensis has a translucent or almost transparent
