Spiral Extinguisher-moss - Encalypta streptocarpa


    This moss forms relatively large, dull, pale green patches. Shoots are typically 1to 2 cm tall, with leaves 4 to7 mm long. The broad, more or less parallel-sided, opaque, very matt leaves narrow abruptly to a blunt, rounded tip, with the nerve ending in, or just below, the tip. Clusters of brown, thread-like propagules often occur in the leaf axils. Capsules are rarely present. They are spirally ribbed, have a peristome, and until maturity are entirely covered by the very large calyptra. This is the commonest species of Encalypta, but the only one in which capsules are rare.
