New synonyms, morphological characterizations and national records for three neotropical Lejeunea species, including comments on distribution and ecology, are presented. Lejeunea cristulata (Steph.) M.E.Reiner & Goda (= L. resupinata [Steph.] Steph., syn. nov.) is newly recorded for Venezuela, Peru and Bolivia. Lejeunea diversicuspis Spruce (= L. megalantha Spruce, syn. nov.; = L. erostrata M.E.Reiner & Goda, syn. nov.) is until now only known from type materials collected by Richard Spruce at the Rio Negro and is new to Venezuela. Lejeunea laeta (Lehm. & Lindenb.) Lehm. & Lindenb. (= Lejeunea diversistipa Lindenb. & Gottsche, syn. nov.) is newly recorded for Venezuela, Peru and Bolivia, and is newly lectotypified. A list of new names in Lejeunea published since the appearance of the World Checklist of Hornworts and Liverworts is presented.

This is the first record of the intentional consumption of moss spores by an arthropod. A moss mite Kunstidamaeus lengersdorfi (Oribatida: Damaeidae) was observed in Moscow Province, Russia, as regularly visiting mature capsules of the moss Schistostega pennata (Schistostegaceae) and eating spores from the opened capsules. The spores of Schistostega are thin-walled, sticky, not dispersed by wind, and exposed at the capsule mouth for easy consumption, being very similar in this respect to the spores of the entomochorous mosses of the Splachnaceae family. Walking through Schistostega population, these mites carry a lot of its spores of their bodies. According to published data, Kunstidamaeus is mostly feeding on saprotrophic fungi and green algae. Behavioral observations as well as the gut content study show that Kunstidamaeus lengersdorfi can also feed on spores of Schistostega pennata . This is the first record of Kunstidamaeus len g ersdorfi in Russia. Previously it was known in Central Europe at cave entrances. In a parallel way, Schistostega grows in Central Europe mostly in caves, while it recently explosively spread in boreal, especially spruce-dominated forests in the Central European Russia. The available data indicate that the mite range expansion had followed the expansion of its forage plant.

Bryophytes occurring in riparian systems where they are seasonally submerged or inundated are poorly documented in many parts of the world. The actual number of rheophytic bryophytes remains speculative but we believe the number could easily exceed 500 taxa. Rheophytic bryophytes generally display highly disjunct populations and adjacent rivers and streams can have considerably different species composition. Water management in the form of flood control, dams, and hydroelectric development can adversely impact many rheophytic bryophyte species and communities due to changes in river ecology, timing of water flow, and water temperature. Specimens of rheophytic bryophytes are underrepresented in herbaria and labels rarely indicate the actual micro-habitat and ecological attributes for bryophytes collected within riparian systems. Many rheophytes are morphological anomalies compared to their terrestrial relatives and the evolution of the rheophytic condition has occurred repeatedly in many bryophyte lineages.

Cyclolejeunea is a small neotropical genus of six species and a common epiphyllous hepatic in lowland and montane rainforests. We describe the new species Cyclolejeunea glimeana M.E.Reiner & Gradst. from wet lowland rainforest along the Pacific coast of Colombia (Choco). The new species is characterized by the absence of innovations, entire leaf margins, leaf lobules without any indication of a tooth, and ligulate, thalloid gemmae without rhizoids. The combination of morphological characters seen in C. glimeana sets this species well apart from the remaining members of the genus and warrants its placement in a separate subgenus, C. subg. Chocolejeunea M.E.Reiner & Gradst. subg. nov. Ecologically, the new species stands out by its preference for palm trunks. The new species is a further addition to the unusually rich flora of the Choco region.

A comparative study of epiphytic bryophytes on tree trunks was undertaken in three principal vegetation types along an elevational gradient on the windward wet side of the largest island in Fiji, Viti Levu. This ecological study is the first of its kind for Fiji and the islands of the South Pacific and it serves as groundwork for any future ecological research in the region for bryophytes. This study set out to test if elevational range of study sites and height along host tree stem influenced bryophyte species diversity and distribution in Fiji. This was done by assessing bryophyte species presence/absence on the lower stems of the Calophyllum spp. trees and tree fern species at three elevations (~160 m, 590 m, and 1260 m). There were two main findings that emerged from this preliminary assessment. Firstly, there was a hump-shaped distribution of bryophyte diversity with a peak of species richness observed at mid-elevation or in the upland forest; with a dominance of liverworts at each of the three elevations. Secondly, the bryophyte communities showed good separation at both host tree level and at the site level, reflecting the ecological differences between the different host trees and between the three sites along the elevational gradient. The results from this survey alone suggest the need for priority to be given to upland forest protection and conservation. It also demonstrates the usefulness of bryophyte communities in discerning vegetation of different environmental and microclimatic conditions along an elevational gradient.
在斐济最大的岛屿维提岛的迎风湿侧沿海拔梯度对树干上的三种主要植被类型的附生苔藓进行了比较研究。这项生态研究是斐济和南太平洋岛屿的首次此类研究，它为该地区未来任何苔藓植物生态研究奠定了基础。本研究旨在测试研究地点的海拔范围和沿寄主树茎的高度是否影响斐济苔藓植物的物种多样性和分布。通过对三种海拔高度(~160 m, 590 m和1260 m)的Calophyllum树种和tree fern树种的下茎上苔藓物种的存在/缺失进行评估，得出了两个主要结论。首先，苔藓植物多样性呈驼峰状分布，物种丰富度在中高海拔或山地林中达到高峰;在三个海拔高度均以苔类植物为主。其次，苔藓植物群落在寄主树水平和立地水平上均表现出良好的分离性，反映了不同寄主树和3个立地在海拔梯度上的生态差异。仅这项调查的结果就表明，需要优先考虑高地森林的保护和养护。这也证明了苔藓植物群落在海拔梯度上识别不同环境和小气候条件下植被的有效性。

A recent collection of Platydictya minutissima from Kentucky, U.S.A., prompted a re-examination of the species. Based on rhizoid placement and pseudoparaphyllium form, the taxon is transferred to Serpoleskea as S. minutissima (Sull. & Lesq.) W.R.Buck & B.H.Allen. The species is restricted to eastern North America. Ecologically the taxon grows on moist rocks in or along streams, becoming submerged at times of high water.

Orthotrichum fenestratum Card. & Ther , described from St. Paul Island and reported only from a few small islands in the Bering Sea and Aleutian Chain, was considered unique because of perforations in the exostome. Comparisons with the uncommon, but widespread, arctic-montane species, O. pylaisii Brid . , indicates that like O. fenestratum , O. pylaisii also has exostomial perforations and these species are conspecific. The distribution of O. pylaisii is mapped for northwestern North America. Orthotrichum sordidum Sull. & Lesq. was described from eastern North America and then reported from East Asia and from scattered locations in Alaska and Greenland. All of the Alaskan specimens are O. pylaisii and also all of the Greenland specimens examined belong to this latter species; consequently O. sordidum should be removed from the floras of these northern regions. Similar to O. pylaisii, O. sordidum also has perforate (and fenestrate) exostome teeth, but differs in a number of features, including 8 vs.16 exostome teeth; deeply ribbed, emergent capsules vs. lightly ribbed, exserted capsules; and 8, well-developed endostome segments vs. rudimentary segments of O. pylaisii . Orthotrichum sordidum occurs almost exclusively on tree trunks, while O. pylaisii occurs on rock.
