Tylopilus dunensis (Boletaceae, Basidiomycota): notes on morphological, phylogenetical and distributional aspects

2024-01-02T13:34:56+00:00

Tylopilus is a worldwide distributed genus of boletes with about 100 known taxa, of which at least 16 are from Brazil and Guyana. Tylopilus dunensis, a species originally described from sand dune habitats in the state of Rio Grande do Norte in northeastern Brazil, has now been recovered in a ‘tabuleiro’ (i.e., tableland forest) from Paraíba. The main phenetic features of this still poorly known species are the orange to orange-ochraceous pileus with yellowish brown margins, unchanging pileus context, the pale cream hymenophore with wide pores, the yellowish stipe, the small and narrow basidiospores, and the long and frequent dextrinoid pseudocystidioid pleurocystidia. After the discovery of the phylloporoid tube trama in our specimens, we emended tube trama type of T. dunensis.

The genera Hypotrachyna and Remototrachyna (Parmeliaceae, Ascomycota) in northeastern Argentina

2024-01-02T13:47:43+00:00

Morphological, chemical and phylogenetic examination of the lichen genera Hypotrachyna and Remototrachyna (Parmeliaceae, Ascomycota) revealed the presence of 12 species in northeastern Argentina. Three of them, H. osseoalba, H. subformosana, and R. costaricensis, are recorded for the first time for the country. The known distribution range of other eight species in the region is also extended. Distribution and comments are presented for all species, and descriptions and illustrations for most relevant records. The phylogenetic relationships of the species of Hypotrachyna and Remototrachyna reported from northeastern Argentina are analyzed.

Syntrichia ruralis as a suitable bioindicator for urban areas – the case study of Tallinn city

2024-01-02T14:06:28+00:00

Environmental pollution is one of the most important problems in urban environment. Mosses are good indicators of air pollution. In Estonia, heavy metals have been measured from Pleurozium schreberi and Hylocomium splendens, which do not grow in areas of Tallinn with a higher pollution load. In the present study, Cu, Fe and Cd were measured from five moss species growing in contaminated as well less polluted areas of Tallinn. Based on stationary and street pollution source inventory and air pollution dispersion modelling, the long-term average concentrations of fine particles (PM10) and nitrogen oxides (NOx) in air were estimated. The work revealed that it is possible to find a moss species that is common in Tallinn and grows in both polluted and less polluted areas – Syntrichia ruralis, which is the most suitable species for bioindication based on this work. Moss species Ceratodon purpureus accumulated the most Cd, Cu, and Fe, then Brachythecium rutabulum/Sciuro-hypnum curtum, and Rhytidiadelphus squarrosus the least. Statistically significant higher Fe concentrations were in the Syntrichia ruralis, compared to the Sciuro-hypnum curtum and Rhytidiadelphus squarrosus. The Syntrichia ruralis also had significantly higher Cd content compared to the Brachythecium rutabulum/Sciuro-hypnum curtum. The results of the GLM analysis showed that the content of various heavy metals depends on the moss species and the degree of fine particles in the environment, and it didn't depend on whether the moss grows on the soil or a hard substrate such as concrete, stone or asphalt.

Updates to the species list of Estonian bryophytes

2024-01-02T14:24:59+00:00

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 records of pyrenocarpous lichens from the Philippines

2024-04-19T09:15:29+00:00

Pyrenocarpous lichens are an important component of the forest ecosystem, yet remain understudied. Following the recent field surveys of the lichen biota in Mt. Musuan, four pyrenolichen species previously unreported from the Philippines were collected, namely: Porina exocha, Pyrenula pyrenuloides, P. subsoluta, and Nigrovothelium inspersotropicum. Each species is briefly described with morphology and chemistry, distribution, ecology, notes, and illustrations. These collections underscore the need for expanded research attention to fully catalogue the lichen diversity in the Philippines.

The lichen genus Sarcogyne (Acarosporaceae) in Belarus

2024-07-02T17:09:23+00:00

The lichen genus Sarcogyne in Belarus is revised. Three species are accepted as occurring in the country, namely Sarcogyne belarusensis, S. hypophaea, and S. pruinosa. Of these, Sarcogyne belarusensis is the most widely distributed and commonest species. Sarcogyne pruinosa and S. hypophaea are rare taxa known from two and one localities, respectively. Morphological characters of these species are provided in comparison with similar taxa.

Updates to the list of Estonian lichenized, lichenicolous and allied fungi

2024-08-02T09:37:58+00:00

Herewith, we continue to upgrade the Estonian checklist of lichenized, lichenicolous and allied fungi, and report thirteen fungal species and one variety as new for Estonia, of them nine are lichenized and five are lichenicolous. Two species – Acarospora oligospora and Lathagrium auriforme – considered to be extinct in Estonia were rediscovered. One species, Usnea articulata, is excluded from the checklist of Estonian lichens.
