Distribution
Endemic. South Island, Castlehill Area
Features
Autoicous, extremely small, tufted, saxicolous, whitish-green moss. Stems less than 1 mm tall, fastigiate. Leaves suberect to spreading; lamina linear-lanceolate, acute or shortly acuminate, concave; margin entire. Nerve failing below leaf apex. Upper cells punctiform. Perichaetial bracts erect, triangular, acute, almost 1/2 length of upper leaves, concave, with margin entire and nerve percurrent. Seta strongly falcate or cygneous. Capsule ovate or subglobose; mouth wide. peristome teeth 16.
Fruiting
Although fruit has been seen insufficient information exists to provide any details on the timing of fruiting
Threats
Very vulnerable to competition from weeds, trampling by rock climbers and mining/quarrying for lime and limestone rock. There is some evidence that this species has declined markedly since rock climbing became more popular in the Castlehill basin.
