Orthotrichum anomalum

Series: Belgian bryophyta

Orthotrichum anomalum (NL: Gesteelde haarmuts / EN: Anomalous Bristle-moss / DE: Stein-Goldhaarmoos / FR: ? ) differs from most members of the genus in growing on rocks or masonry rather than trees. It is a more or less ubiquitous species, found on concrete, gravestones, wall tops and other man made structures. Also common on exposed limestone, but absent from chalk. It is not found on acidic rock. O. anomalum occasionally grows on trees and shrubs, which can be very muddling! The dark reddish-brown ripe capsules of O. anomalum are held well above low cushions of straight-leaved, green or brown shoots on a 2–4 mm long seta: a distinctive appearance not shared by other common mosses of the lowlands, except Ulota species that grow on trees and shrubs. Each capsule has 16 erect outer peristome teeth and strong ribs when it is dry. Mature capsules are reddish-brown, but light green when unripe. The calyptra is light brown and is sparsely hairy. Shoots are typically about 1.5 cm tall, with leaves 2.5–4 mm long, and capsules about 2 mm long.

Leuk, die twee in één druppeltje. Ik ben benieuwd of er ook achterlichtjes in je serie zitten.

@christine: Dat was ook het detail dat mij opviel en de foto net dat tikje extra gaf ten opzichte van andere van dezelfde soort. De achterlichtjes stonden er ook ... :-) ... Groetjes !
