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.

Five lichen species new to Poland

Maria Kossowska — 2022-06-30

Athallia cerinelloides, Caloplaca ulcerosa, Flavoplaca arcis, Lecanora sinuosa and Sclerophora amabilis are reported for the first time from Poland. Descriptions, notes on similar species, habitat preferences and general distribution are provided for each species.

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.

New records of lichens and allied fungi from the Leningrad Region, Russia. XII

Dmitry E. Himelbrant — 2022-06-30

Three lichen species and eight lichenicolous fungi were recorded for the first time for St. Petersburg or Eastern Leningrad Region. 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.
