Dicranoloma menziesii is a common and widespread epiphytic moss found in Tasmania, Australia. It grows as loose turfs on rocks, logs and trees in wet forest and rainforest.

D. menziesii belongs to the Dicranoloma genus of mosses, and is mainly distributed in the Southern Hemisphere, with 13 species found in Australia and 7 species in Tasmania. Previously, D.menziesii was under the genus Dicranum (Hedw.), however, it was changed to Dicranoloma due to the difference in its leaf border when compared to the Dicranum mosses in the Northern Hemisphere.

Description
The Australasia Dicranoloma mosses are dioecious; bearing male and female reproductive organs on separate gametophytes, and exhibit sexual dimorphism. The male plants are mostly dwarfed and grow in clusters among the stem tomentum of females or occasionally at the leaf base. They grow up to 0.5- 3.0 mm tall, while the female plants can grow up to 13 cm tall.

 * 334x334px]]Dicranoloma menziesii has erect shoots that are 2.5 to 10.0 cm tall. The stem is reddish brown in color, and is surrounded by densely tomentose leaves.The leaves are smooth, falcate-secund, erect, thin and long with colours ranging from yellowish green to dark green. Each leaf is roughly 9.0 to 14.0 mm long, and 0.9 to 1.2 mm wide. Costa is 106-139 μm wide and 46-57 μm thick. It also has a straight to slightly concave adaxial surface and a convex abaxial side. Teeth at leaf margin is 3-8μm. At the shoot apex, short urn-like modified leaf structures known as perichaetium are formed when mature.

Sporophyte
The seta, which is a thin, smooth and long stalk supporting the capsule of D.menziesii, is 4.5 to 8.0 mm long. It has a red base that darkens as it approaches the cylindrical and slightly curved capsule. The calyptra is 2.5-2.8 mm long, yellowish to transparent in color, and brown at the apex. The peristome teeth is 620-660 μm long and 86-109 μm wide at base. It is orange at the basal half of the peristome teeth, and yellow at the tip. The annulus is two cell thick, and the operculum 1.6 - 1.8 mm. Mature spores are spherical and 16-19 μm in diameter.

Dicranoloma menziesii is most often confused with Holomitrium trichopodum from the family Dicranaceae, because they both have vegetative similarities; but the former species is distinguished by having larger leaves (over 0.9 cm) and having teeth on the leaf margins throughout the upper part of the leaf. When sporognium is absent, D.menziseii may be confused with D. trichopodum.

Habitat and Distribution
Dicranoloma menziesii can be found in Australia ranging from North-eastern Queensland to Southern Victoria, as well as the cool temperate regions in Tasmania.

The moss commonly grows in wet, humid forests at altitudes 1550 m above sea level. It is usually found on rocks, logs, tree stumps, tree bases and lower tree stems of rainforest species such as Nothofagus cunninghammii, where it is least prone to desiccation. When plant species such as Nothofagus cunnighamii, Atherosperma moschatum, Eucalyptus regnans and Anodopetalum biglandulosum are present at the same site, the vegetation type can be classified as a cool temperate rainforest.

Reproduction
Antheridia, the male reproductive organ, first develops in winter (June). By Spring, it develops into an Immature stage and remains as such for 4 months (September - January) until it matures. A mature antheridia requires a total of 7 months to develop. During Spring, the development of the immature antheridia also initiates the growth of the archegonia, which is the female reproductive organ. The growth of the archaegonia is more rapid than its male counterpart and only takes approximately 2 months to reach maturity.

Fertilisation occurs within the perichaetum from January to March (Late Summer). After fertilization, sporophyte formation takes place. Firstly, the setae starts to grow and the capsule starts to expand from August to November. As it reaches maturity, the capsule is dehiscent. At maturity, the capsule breaks and the spores are dispersed. Sporophyte development and maturation of Dicranoloma menziesii takes 10-12 months.
