15Tropical Bryology 10: 15-20,   1995Mosses New to Hong Kong  (III)M.L.So1 and K.L.Yip21  Biology Department, Hong Kong Baptist University, 224 Waterloo Road, Kowloon, Hong Kong.2  Department of Biological Sciences, University of Cincinnati, Cincinnati, OH 45221-0006, USA.Abstract.    Ten moss species - Philonotis turneriana  (Schwaegr.) Mitt.,  Fissidens javanicus Dozy& Molk.,   Lopidium nazeense  (Ther.) Broth.,  Himatocladium cyclophyllum (C. Muell.) Fleisch.,Homaliodendron exigiuum (Bosch & Lac.) Fleisch.,  Homaliodendron microdendron (Mont.) Fleisch.,Homaliodendron scapellifolium (Mitt.) Fleisch.,  Pinnatella anacamptolepis (C.Muell.) Broth.,Calyptothecium wrightii (Mitt.) Fleisch.  and  Haplocladium angustifolium (Hampe & C. Muell.) Broth.are reported new to Hong Kong.  Among them, four are new to Guangdong Province of China.  Anupdated checklist of Hong Kong mosses is provided.A locality near the summit of Tai Mo Shan, at analtitude of 700m, appears to be rich in rare mossspecies.  It is a shaded area near a stream filled withrocks of varying sizes.  Most of the mosses areepilithic, some are epiphytic.  All species werecollected during the summer of 1994.The new records are listed below.  Since HongKong is now part of the Guangdong Province ofChina, those new to Guangdong are marked withan asterisk.An updated checklist of Hong Kong Mosses isalso included.Bartramiaceae* Philonotis turneriana  (Schwaegr.) Mitt.This species was found in a large patch attachedto a moist rock crevice.  The terminal part has acluster of closely arranged leaves, yellowish greenin colour.  The proximal part is dark brown producingclusters of rhizoids.  The stem is 20-30 mm long,with lanceolate leaves which are slightly appressed.No capsule was observed.(So 94808A Verified by P.C.Wu)FissidentaceaeFissidens javanicus Dozy & Molk.This species is fairly common on moist rocks nearstreams at an elevation of 300 m or above.  The stemis 6-10 mm long, bearing yellowish green leaves16which have a characteristic rugose appearance onthe dorsal surface.  Capsules have not beenobserved.(So 93824F, Verified by Z.H.Li)Hypopterygiaceae* Lopidium nazeense (Ther.) Broth.This is an extremely rare species, found on thesurface of only one rock.  Superficially, it resem-bles Hypopterygium tenellum which grew in thesame spot, but the leaves are brighter green incolour.  It is characterized by having a creepingrhizome producing stout stipes and erect pinnatebranches.  The leaves are complanately arranged,and the costa is distinct and stout, shortly excur-rent and slightly curved to one side of the leaf.(So 94617A, Verified by P.C.Wu)NeckeraceaeHimatocladium cyclophyllum (C. Muell.)  Fleisch.This is again a moss of high altitude and is foundcreeping along rock surfaces.   It usually occurstogether with Thanobryum plicatum and Homa-liodendron scapellifolium in a large patch.  It hasa distinctive, tree-like appearance and the leavesare almost rectangular in shape with a truncatedtip.  The plant is robust, green, not at all glossy.The leaves (to 5 mm long) are densely and spirallyarranged along the branches.  No capsules wereobserved.(So and Yip 94830, Verified by L. Zhang)Homaliodendron exiguum (Bosch & Lac.)Fleisch.This is a common epilithic species which is foundin almost all streams with rocks.  Erect branches areproduced from the rhizome which creeps overmoist rock surfaces.  The plant is fairly small,slightly glossy and the stems seldom grow to morethan 30 mm long and 2 mm wide with leaves.  Thestems are sparsely branched, and branches arevery short.  Capsules have not been observed.(So 93824, Verified by D.K.Li.)Homaliodendron microdendron (Mont.)Fleisch.This is a rather common moss species foundattached to base of trees or moist rock surfaces.Superficially, it bears some resemblance toHomalia trichomanoides but it is larger and glos-sier than the latter, which is a species of moist rocksurfaces.  The secondary stems are bi-to tripinnatelybranched and may grow to 60 mm long and 5 mmwide with leaves; branching is pinnate.  Capsuleshave not been observed.(So & Yip 94830H, Verified by Z. Iwatsuki)Homaliodendron scapellifolium (Mitt.) Fleisch.This is one of the largest moss species found inHong Kong and a very common one, on rock nearstreams, at an altitude of 400 m and above.  It isfairly easily recognized, with a distinct stipe, erectstem and complanate leaves.  The erect stems maygrow to 110 mm and are bi- to tripinnately branched,producing a large fan-like frond.  The leaves on thesecondary stems are broadly acute, to 5 mm long.One feature of the leaves is the sharply dentate tipwhich distinguishes it from the otherHomaliodendron species in Hong Kong.  Nocapsules were seen.(So 94617C, Verified by L. Zhang)* Pinnatella anacamptolepis (C. Muell.) Broth.This is a rare species which was found on one rocksurface in deep shade at an altitude of 700 m.  It isa robust moss with a tree-like appearance and aleafless rhizome which creeps over the substrate.The stems with a distinct stipe are semi-erect,complanately and pinnately branched.  No capsu-les were found.(So 94617C, Verified by L.Zhang)Pterobryaceae* Calyptothecium wrightii (Mitt.) Fleisch.This is a rare species which was found creeping onthe surface of a rock at an altitude of 700 m.  Theplant is robust, dull green in colour and slightly17glossy.  The long rhizome produces distinctlyspaced erect secondary stems which are pinnatelybranched.  No capsule was observed.(So 94520A, Verified by L. Zhang.)ThuidaceaeHaplocladium angustifolium (Hampe & C.Muell.)  Broth.This is a common species which can be found onsoil bank or rock surfaces at an altitude of 300 m orabove.  The plant is delicate, bi-pinnately branched,green above but brownish green below.  Theleaves are erect spreading when moist, but closelypressed together when dry.  Capsules arenumerous, with a seta of 7 mm.(So 93914B, Verified by S.H.Lin)An alphabetical list of Hong Kong mossesThe first checklist of mosses was compiled byDixon more than 50 years ago (Dixon, 1933).  Thefollowing is an updated checklist of mosses whichincludes all the new records reported since.The published records are cited by the abbrevia-tions given below.  The generic and species nameswhich have been updated, follow that of Redfearn(1992).  Synonyms are not included.Literature abbreviations:BG = But & Gao 1991D = Dixon 1993GB = Gao & But 1992H = Henry 1929M1 = Mitten 1865M2 = Mitten 1891R = Reimers 1931S = Salmon 1900SL = Sullivant & Lesquereux 1859SS = So & So 1994SY1 = So & Yip 1994SY2 = So & Yip present reportW = Wilson 1848Aerobryidium wallichii (Brid.)
