New Estonian records: Lichenicolous fungi

Lichenodiplis lichenicola Dyko & D. Hawksw, the third Lichenodiplis (Chaetothyriales, Eurotiomycetes) species found from Estonia besides L. lecanorae and L. pertusariicola (syn. Laeviomyces pertusariicola)

The species of the former Toninia coeruleonigricans group in Estonia

The Estonian specimens originally named Toninia coeruleonigricans auct. (= Toninia caeruleonigricans), formally revised as Toninia sedifolia were checked again recently. Two species, T. physaroides (Opiz) Zahlbr. and T. sedifolia (Scop.) Timdal were recognized. A key for determination of sterile specimens of the closely related taxa T. opuntioides (Vill.) Timdal, T. physaroides and T. sedifolia is provided.

Excluded species of lichenized and lichenicolous fungi

Since the publishing of the Second checklist of Estonian lichenized and allied fungi (Randlane & Saag, 1999), and its updates, fifteen species have been excluded as misidentifications (Randlane et al., 2008).

Estonian Mycological Society: 60 years!

Sixty years ago, on December 23, 1963, 15 members of the Estonian Naturalists’ Society decided to establish a separate unit within the society – a section of mycology. The initiative came from Erast Parmasto (1928–2012), whose idea was to establish an organization that would consolidate and coordinate activities of professional mycologists from various institutions and fungal enthusiasts in Estonia in order to promote exploration of local mycobiota

The mycological collection of G. C. Girgensohn from the middle of the 19th century

Since 1844, vouchers of mycological specimens collected from the territory of the historic Baltic provinces of the Russian Empire have been preserved in Estonian natural history collections. A pedagogue and an amateur bryologist, Gustav Carl Girgensohn (1786–1872) compiled a collection of 109 specimens of fungi and myxomycetes sampled from the Livonian Governorate, mostly from the vicinity of Tartu, in years 1844–1859. Girgensohn’s collection, which is kept in the fungarium of the Estonian University of Life Sciences, is introduced here for the first time. Among his specimens there are two notable ascomycetes—coprophilous Poronia punctata (Xylariaceae, Sordariomycetes), recently evaluated in Estonia as Critically Endangered according to IUCN criteria, and Microstoma protractum (Sarcoscyphaceae, Pezizomycetes), recently evaluated as Endangered. The collection’s eleven quite well-preserved specimens of myxomycetes represent six species, the least common of which is Diderma radiatum. In addition, the article introduces nine lichen specimens and one fungal specimen from Girgensohn’s bryophyte collection at the Natural History Museum of the University of Tartu. The most remarkable species among this collection is Lobaria pulmonaria (Lobariaceae, Lecanoromycetes), red-listed and protected in many countries

New Estonian records: Lichenized and lichenicolous fungi

Two species of lichenized fungi, Bacidina sulphurella and Xanthomendoza oregana, and three species of lichenicolous fungi are reported as new for Estonia. Cited specimens are kept in the lichenological herbarium of University of Tartu Natural History Museum and Botanic Garden (TU)

New Estonian records and amendments: Lichenized and lichenicolous fungi

Two species of lichenized fungi, Rhizocarpon ferax and Umbilicaria hirsuta, and one species of lichenicolous fungi, Opegrapha physciaria, are reported as new for Estonia. Another very rare species, Parmelia submontana, is additionally recorded. Cited specimens are kept in the lichenological herbarium of the Natural History Museum, University of Tartu (TU) or in the lichen herbarium of the Euroacademy (ICEB).

Lichenicolous fungi of southern Scandinavia with particular reference to those associated with Xanthoria calcicola s. lat.

Lichenicolous fungi associated with Xanthoria calcicola s. lat. are studied in southernmost Scandinavia, i.e., Skåne, the southernmost province in Sweden and southern Denmark. Two species, Didymocyrtis slaptoensis and Pyrenochaeta xantho­ riae, are reported as new for the Nordic countries, whereas three species, Didymocyrtis cf. consimilis, Erythricium aurantiacum, and Illosporiopsis christiansenii are recorded for the first time from Skåne. New localities for rare lichenicolous fungi from southern Scandinavia and southernmost Denmark are also listed. Notes on the taxonomy and ecology of Telogalla olivieri and Pyrenochaeta xanthoriae are provided

New Estonian records and amendments: Lichenized fungi; Lichenicolous fungi

Three species of lichenized fungi, Caloplaca dischroa, Rhizocarpon submodestum, and Rimularia intercedens, are reported as new for Estonia; one taxon, Diplotomma lutosum, which was previously considered to be extinct from the local lichen biota, was re-discovered. Two further rare species, Collema crispum and Leptogium plicatile, are additionally recorded. Five species of lichenicolous fungi are reported as new for Estonia.

New Estonian records and amendments: Lichenized and lichenicolous fungi

15 species are reported as new for Estonia, of them 8 are lichenized and 7 are lichenicolous fungi. The presence of Epiphloea byssina, previously known by old literature data only, is confirmed. Collema occultatum and Peltigera elisabethae, previously considered to be extinct from the local lichen biota, were re-discovered. Record of Psorotichia schaereri is the second finding of this taxon in Estonia.
