Abstract Riccardia is a large genus of thalloid liverworts and notoriously difficult in terms of species recognition. Thirty six species were recognized in the tropical Andes but many of these are not well-defined. In this paper fourteen species are accepted for Colombia and Ecuador; eighteen species and two varieties are reduced to synonymy. Descriptions and illustrations are provided for the accepted species together with a key and data on types, synonymy, geographical distribution, habitat and differentiating characters. Riccardia palmata and R. multifida are excluded from the flora of Colombia and Ecuador. The new combination Riccardia latifrons subsp. parasitans (Steph.) Gradst. & Reeb comb. nov. is proposed and eighteen new lectotypifications are made.

Abstract After the discovery of two Macromitrium species with aristate leaves, new to science, in New Caledonia, another aristate species, M. panduraefolium, is described and commented on herein. It is distinguished from the formerly known species by its smaller size, leaves spirally coiled around the branch axis and branch leaf shape narrower at the middle. Its ecology and its status are discussed. In addition, the author provides a key to the aristate species known from the region including Malesia, Australasia, Pacific Islands and Melanesia.

Abstract The fourth edition of the Red List of Liverworts and Hornworts of Poland was prepared using the rules presented in the 2nd edition of the International Union for Conservation of Nature Red List Categories and Criteria (version 3.1). Altogether, 240 liverwort and four hornwort species that are currently found in Poland are included. Seventy-two species (71 liverworts and one hornwort) are classified as threatened, which comprises 30% and 25% of the liverwort and hornwort flora, respectively. The critically endangered (CR) category is assigned to 11 liverworts and one hornwort, the endangered (EN) category is assigned to 21 liverworts, and the vulnerable (VU) category is assigned to 39 liverworts. Two liverwort species, Anastrophyllum donnianum and Biantheridion undulifolium, are considered regionally extinct. Data concerning the distribution, abundance and population state of 21 species (20 liverworts and one hornwort) fall within the data deficient (DD) category; in this category, the data are insufficient for the established criteria to be used to determine the endangerment category. One liverwort is included in the not applicable (NA) category.

Abstract Macromitrium fortunatii Thér. was included in the first Red List of Chinese endangered bryophytes, but later its inclusion was considered as uncertain because of taxonomic uncertainty and insufficient distribution data. Though the species was recently excluded from the latest threatened species list of China's higher plants, no detailed geographical records, voucher specimens or relevant references were included. From our morphological studies of type and other specimens, together with phylogenetic analyses based on ITS2, trnL and trnG sequences, we confirm its taxonomical identity and provide a detailed description and illustrations of the species. Macromitrium fortunatii var. nigrescens Tixier is reduced to synonymy with M. fortunatii. Since 2013 we have found 24 populations of M. fortunatii in Southwest and South China and North Vietnam. According to nine environmental variables and recent records of the species, we predict its potential distribution range with an aid of the maximum entropy algorithm modeling program (Maxent) and ArcGis 10.2. We find a high environmental suitability of the species in a wide region covering South and Southwest China, North Vietnam, North Myanmar, Nepal, and Northeast India. The predicted climate suitability for M. fortunatii is highest in areas where the annual precipitation is 1200 mm, the driest quarter receives 50 mm, and the wettest month 250 mm, the mean temperature of the coldest quarter is 10°C, and the altitude is about 1200 m. The exclusion of M. fortunatii from the threatened species list of China's higher plants is supported.

ABSTRACT A new population of the Argentinian endemic Riella choconensis Hässel (Riellaceae, Marchantiophyta) was discovered from a culture of sediments from the Laguna de los Juncos (Río Negro province, Argentina). This species was known previously from two nearby collections, made in 1984, in the type locality at the Ramos Mexía reservoir (Neuquén province) and was not recorded since. Fresh material from the new population enabled detailed morphological analyses, which are extensively described here, illustrated and compared to type material of the species. Based on the smooth female involucre, the species belongs to subgenus Riella Mont. However, cross-sections of this structure showed that R. choconensis has bistratose involucre walls, contrasting with the unistratose female involucres of all other species in the genus. The updated morphological data are integrated into a new key to the identification of the American species of Riella.
在阿根廷内negro省Laguna de los Juncos沉积物培养物中发现了阿根廷特有的Riella choconensis Hässel (Riellaceae, Marchantiophyta)新种群。该物种以前是在1984年在Ramos Mexía水库(neuqusamn省)的类型地点附近的两个标本中发现的，此后没有记录。来自新种群的新材料可以进行详细的形态分析，这里对其进行了广泛的描述，说明并与物种的模式材料进行了比较。从光滑的雌总苞来看，该种属于蕊花亚属。然而，这种结构的横切面显示，与所有属其他物种的单苞总苞壁形成对比的是，长叶小檗具有双苞总苞壁。更新的形态学数据被整合到一个新的关键，以鉴定Riella美洲种。

Abstract We describe Pycnolejeunea chocoensis M.E.Reiner & Gradst. sp. nov. from wet lowland rainforest along the Pacific coast of Colombia (Chocó). The new species is distinguished by small decurved lobules, absence of ocelli and small, distant underleaves. Pycnolejeunea chocoensis is a further addition to the unusually rich flora of the Chocó region.

Abstract The study of the type specimen of Bartramia minuta Taylor, a species described based on Ecuadorian samples that predates the recently resurrected Chilean Philonotis brevifolia Herzog shows that both names displayed the same set of diagnostic characters. In this contribution, P. minuta is proposed as the correct name of this taxon, a lectotype is selected, and its distribution is extended to North America, based on samples collected in California.
