Hasselquist's Hyssop
Entosthodon fascicularis
Hasselquist's Hyssop (Entosthodon fascicularis) is a small, cushion-forming moss species characterized by its densely clustered shoots and distinctive fasciculate (bundled) leaf arrangement. This bryophyte produces small, erect capsules on short setae and plays an important ecological role in soil stabilization and microhabitat creation for invertebrates in arid environments.

Species Profile
Hasselquist's Hyssop (Entosthodon fascicularis) is a small, cushion-forming moss species characterized by its densely clustered shoots and distinctive fasciculate (bundled) leaf arrangement. This bryophyte produces small, erect capsules on short setae and plays an important ecological role in soil stabilization and microhabitat creation for invertebrates in arid environments.
Hasselquist's Hyssop (Entosthodon fascicularis) is critically endangered due to its extremely limited distribution and habitat degradation. This moss species faces severe threats from urban development, agricultural expansion, and climate change affecting its specialized Mediterranean habitat requirements.
Key Facts
Habitat & Distribution
Entosthodon fascicularis inhabits exposed calcareous soils, limestone outcrops, and disturbed ground in Mediterranean and semi-arid regions. It typically colonizes thin soil layers over rock substrates and can be found on walls, path edges, and other anthropogenic surfaces with suitable alkaline conditions.
