Flabellidium spinosum is an extinct species of the moss class. It was endemic to Bolivia and is considered the only species in the genus Flabellidium .
features
Flabellidium spinosum was a pleurocarpes, epiphytic moss growing on tree roots with dirty-green to yellowish-green leaves. The erect stems were about 1 cm high, semi-pinnate and more or less leafy. The egg-shaped leaflets measured 0.7 × 0.35 mm. They were flaky and slightly arched when dry. The abaxially serrated central rib (costa), emerging as a thorn, reached about three quarters of the leaf length. Flabellidium spinosum was presumably diocese . No sporophytes have become known. The bald, light yellow spore capsule hood was 1.8 mm long. The reddish capsule stem was smooth. The capsules were underdeveloped.
status
Flabellidium spinosum is only known of the type material that the German botanist and bryologist Theodor Herzog discovered in 1911 in the Cordillera Quimsa Cruz ( Tres Cruces ) near Santa Cruz de la Sierra in Bolivia in a mountain forest at an altitude of about 1400 m. The forest in the type locality and in the vicinity was cleared and the region was converted into agricultural land. The species could not be rediscovered in subsequent expeditions and is now considered to be most likely extinct.
