Morphology and habitat properties of Tortula lingulata in Estonia

Tortula lingulata Lindb. is a moss that is rare in Europe and under protection in Estonia. It grows sparsely on sandstone outcrops. Eight localities are known in Estonia. Main morphological characters of the species and environmental parameters were measured at five sites. The moss shoots were longer at sites with higher sandstone moisture, and the nerve of the leaves was wider at sites with higher moisture and conductivity level under the moss patch.

Revised Red Data List of Estonian bryophytes

All Estonian bryophyte species (597) that had written records up to 2018 were evaluated against IUCN criteria. More than half of the species belong to the least concern category, but almost one fourth (158) is evaluated as threatened, and one tenth (65) as near threatened. Eleven species are data deficient and 15 species are considered to be regionally extinct from Estonia. To achieve adequate assessment results for a small country, some criteria were adjusted. Changes compared to the previous red list and threats to the species are discussed.  This version replaces the version of the same paper from 2018-08-14

Annotated checklist of Estonian bryophytes

The updated list of Estonian bryophytes includes 594 species from all three phyla. Only one species is reported for Estonia according to the literature data, all others have voucher speciemens in herbaria, two of them outside of Estonia. Altogether 242 species are frequent in Estonia, 173 species are rare, and 161 are sporadically distributed. We do not have any recent data for 20 species, and their presence in Estonia is doubtful. In 2008 a new Estonian Red list was compiled and 369 bryophyte species were evaluated against IUCN criteria. Approximately one fifth of the Estonian bryoflora (129 species) is designated to the three threat categories.  Electronic supplement at http://www.ut.ee/ial5/fce/fce52supplement/FCE52_Vellak_supplement.ht

New Estonian records: Mosses

The number of bryophyte species known from Estonia was 583 in 2011 (Vellak et al., 2011). Seven moss species and one subspecies have been identified and added as new to the Estonian bryoflora during last two years.

Additions and changes to the species list of Estonian bryophytes

Since the last additions (Vellak et al., 2021), four new species should be added to the list. Two of these (Calypogeia fissa and Timmia austriaca) are new finds, two (Hedwigia emodica and Syntrichia ruraliformis) were earlier known as varieties in Estonia. One species (Seligeria patula) should be excluded from the list since the voucher specimen was re-identified as S. calcarea and no other specimens were found among all collected specimens of genus Seligeria in Estonian herbaria and during inventories of genus Seligeria at all known localities in Estonia in 2020-2021. The number of species in Estonian bryoflora is now 615. The distribution and threats on the new species in Estonia are not known yet and need further inventories, thus all are evaluated here as data deficient (DD). Estonian names for all new species are presented in parenthesis and the distribution and ecology is briefly discussed

Additions to the Estonian Bryoflora 2019-2021: Liverworts and Mosses

Six species and one subspecies new for Estonia have been found during recent fieldworks. In addition, three varieties from our bryoflora are now accepted as species and so the number of species in Estonian bryoflora is currently 611. Voucher specimens are selected for all new species reported here. Most of the species are included preliminarily into category Data Deficient (DD) according to IUCN structure. Besides this, updated proposals for threat categories are given for four noteworthy bryophytes, which localities were inspected in 2019-2020. Estonian names are given to all new species

Updates to the species list of Estonian bryophytes

Six species are new to the flora of Estonian bryophytes since the last additions: Bryum ruderale, Entosthodon fascicularis and Plenogemma phyllantha have been found during recent fieldworks; Encalypta driva is a newly described species and Lewinskya fastigiata is a new taxonomical combination. Moerckia flotoviana replaces the species Moerckia hibernica since all herbaria specimens are re-identified. After additions and re-arrangements, the number of bryophyte species known from Estonia has risen to 618. For all new species, Estonian names are given, and they are evaluated against IUCN criteria. Two of the species were included in category DD, because of shortage of data; Lewinskya fastigiata was evaluated as LC, and Encalypta driva and Plenogemma phyllantha as VU. The IUCN category of Moerckia flotoviana remained as it was for Moerckia hibernica (LC)

New Estonian records: mosses

In 2016 four species new to Estonia have been identified, mainly by checking earlier collections in different herbaria. This addition raises the total number of bryophyte species registered in Estonia up to 598. One species, which was evaluated as extinct in Estonia, has been found in a new locality. Also a variety new for Estonia has been found.

Additions and amendments to the list of Estonian bryophytes

Five new moss species and one variety are incorporated to the Estonian bryoflora, one species should be eliminated due to recent taxonomical study. The number of bryophyte species has now risen to 602 for Estonia, thus the number of species has doubled since the first published list in 1860
