Validation of the typifications of Pertusaria atropallida and P. uralensis

Magdalena Oset — 2022-04-01

The issue of valid publication and typification of Pertusaria atropallida and P. uralensis is discussed. According to Art. F.5.4 ICN the names were published in 2021 invalidly because the author did not provide a registration number in MycoBank.

Some new lichen records from Pakistan

Iram Fayyaz — 2022-06-30

During a survey of the lichens in the state of Azad Jammu and Kashmir, many specimens were collected from the Jhelum and Neelum valley and characterized using morpho-anatomical, molecular and chemical test methods. Two taxa new for Pakistan, i.e., Physciella chloanta and Xanthoparmelia protomatrae s. l., were found in the collection while Physconia enteroxantha represent range extensions within Pakistan. Morpho-anatomical descriptions, ecology and distribution are provided.

In addition, the protected species Lobaria scrobiculata was rediscovered in the Leningrad Region. The lichenicolous fungus Arthonia parietinaria is new to Russia, and two species, Didymocyrtis melanelixiae and Tremella everniae, are new for European Russia.

Additions and changes to the species list of Estonian bryophytes

Nele Ingerpuu — 2022-07-07

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.

Pleochaeta indica, a new record of powdery mildew from Pakistan

Najam-ul-Sehar Afshan — 2022-07-07

A comprehensive study of a powdery mildew observed on leaves of Celtis tetrandra Roxb. was carried out by the authors. The symptoms appeared as white mycelium on leaves with embedded small black to brown spherical ascomata. Infected plants were collected from Thandiani (District Abbottabad, Division Hazara) of Khyber Pakhtunkhwa province, Pakistan, during a phytopathogenic survey in 2019. The causal agent was observed and identified on the basis of morphological and molecular analyses, which reveals that this fungus belongs to genus Pleochaeta. Further investigation identified it as Pleochaeta indica. This is the first report of a powdery mildew infection caused by this pathogen in Pakistan. A complete description and illustrations of the fungus are presented.

Hornfels rocks as a habitat for saxicolous lichen biota. A case study from the Sudety Mountains (SW Poland)

Maria Kossowska — 2022-07-07

The results of lichenological studies on hornfels outcrops in the Izerskie Mountains (Sudetes, SW Poland) are presented. This substrate is connected with the igneous intrusion into the country rocks and is characterized by a richer chemical and mineral composition than the surrounding rock bodies. In the six analyzed sites, a total of 48 saxicolous lichen species were found. Hornfels as a substrate for lichen vegetation is distinguished by the presence of lichens typical for rocks rich in metal compounds, in the study area represented by Rhizocarpon oederi, Lecidea silacea and Porpidia melinodes, and lichens that prefer mineral-enriched rocks, like Lecanora campestris, L. rupicola, Lecidea fuscoatra, Porpidia cinereoatra and Rimularia gibbosa. The three mentioned metallophilous species are some of the rarest components of the lichen biota in Poland, known from single localities. Other rare and locally endangered lichens recorded on hornfels include Lambiella furvella, Stereocaulon dactylophyllum and Umbilicaria pustulata.

The rare fungicolous fungus Pseudotrichia mutabilis (Pers.) Wehm.: new data and a historical perspective

Olexander Akulov — 2022-10-26

The paper reports two new records of a rare fungicolous fungus Pseudotrichia mutabilis (Melanommataceae, Pleosporales) from Ukraine. Both specimens were collected within protected areas in association with two xylariaceous species, Hypoxylon crocopeplum and Rosellinia corticium. The paper provides descriptions, nomenclatural data, and original illustrations of the reported species. Information on substrate specialization and nutritional strategies of Pseudotrichia mutabilis, as well as general distribution of the species and known localities in Ukraine are specified and summarized.

A recent update in red-listing of Estonian lichens: threat status of 168 species was assessed for the first time

Inga Jüriado — 2022-11-05

The threat status of 168 lichenized species growing mostly on rocks or ground were assessed in 2022 for the first time in Estonia. The IUCN Red List system (categories and criteria) were used for that purpose. Most of the assessed taxa were microlichens (163), while five macrolichen species were also evaluated. Among the assessed species, 91 were assigned to the threat categories (Critically Endangered – CR, Endangered – EN and Vulnerable – VU), 17 species were assigned to the category Near Threatened (NT), and 41 species were assigned to the category Least Concerned (LC). Category Data Deficient (DD) was assigned for 17 species and the category Regionally Extinct (RE) for two species. Among the threat categories, 35 species were assigned to the category EN, 34 species to VU, and 22 species to CR. In general, most of the evaluated species (81%, 137 species) were growing on different types of rock, 16% (28 species) of species were growing on soil, mosses or plant debris, and three taxa were growing on other substrata. Most of the threatened epigeic and epilithic microlichens were recorded on alvar grasslands growing on ground, limestone pebbles and flatrock or erratic boulders. Er- ratic boulders in various forest types and calcareous cliffs in clint forest were also important habitats for threatened species. Moreover, different rock substrates of anthropogenic origin (walls, buildings and abandoned limestone quarries) performed as significant habitat type for epilithic species. Bush encroachment of open habitats, especially in semi-natural grasslands, serves as the main threat for epigeic and epilithic lichens.
