Thiers B.M. (2024): Strengthening partnerships to safeguard the future of herbaria - Diversity, 16(1): 36 [10 p.]

Herbaria remain the primary means of documenting plant life on earth, and the number of herbaria worldwide and the number of specimens they hold continues to grow. Digitization of herbarium specimens, though far from complete, has increased the discoverability of herbarium holdings and has increased the range of studies from which data from herbarium specimens can be used. The rather large number of herbaria about which no current information is available is a source of concern, as is herbarium consolidation … Read more...

Hawksworth D.L. (1979): Studies in the genus Endococcus (Ascomycotina, Dothideales) - Bot. Notiser, 132: 283-290

The generic name Tichothecium Flotow, widely used for lichenicolous fungi, is found to be typified by Verrucaria nigrescens Pers. and so must be placed as a synonym of the lichen genus Verrucaria Schrader nom. cons. A preliminary survey of the fungi formerly referred to Tichothecium shows that they fall into two groups on the basis of the structure of the asci. Those with 4- or 8-spored, bitunicate asci are placed in Endococcus Nyl. (syn. Discothecium Zopf), while ones with multispored asci discharging … Read more...

Jørgensen P. M. & Sipman H.J.M. (2007): The lichen Fuscopannaria leucosticta (Tuck.) P. M. Jørg. found in the tropics - Lichenologist, 39(3): 305-307

In a recent treatment of the Pannariceae of Ecuador, Jørgensen & Arvidsson (2004: 131) pointed out the surprising absence of the genus Fuscopannaria in Ecuador, a genus which is rather common, with many species, in the Pacific Northwest of North America (Jørgensen 2001). The authors claim that, on the western side of the Americas, the genus appears to stop north of Mexico, only to reappear in southern Chile and Argentina. While going through his material, the second author discovered two specimens … Read more...

Suija A., Degtjarenko P., Jüriado I., Martin L., Oja E. & Randlane T. (2024): Updates to the list of Estonian lichenized, lichenicolous and allied fungi - Folia Cryptogamica Estonica, 61: 91–97

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. Read more...

Demková L., Bobuľská L., Harangozo Ľ. & Árvay J. (2023): Using bio-monitors to determine the mercury air pollution in a former mining area - Engineering Proceedings, 57(1): 28 [7 p.]

Total mercury air pollution was evaluated in the former mining area of Gelnica (Slovakia) using tree bark, mosses (Climacium sp., Pleurosium sp.), and lichen (Pseudevernia sp.). Samples were collected (tree bark) and exposed (moss and lichen bags) on the heaps and near the mines. Additionally, the internal parts of the mines were evaluated. The mercury content in the bio-monitors was evaluated using an AMA-254 analyzer. The results showed significant differences in tree bark mercury content between … Read more...
