KOUT J., HAJŠMANOVÁ P. (2015): Kavinia alboviridis in the Czech Republic. [Basidiomycetes, Gomphales, corticioid species, Bohemia] Czech Mycology 67(1): 59-67 (published: 29th May, 2015)
abstract
The distribution of the rare lignicolous species Kavinia alboviridis in the Czech Republic is summarised. Recently the species has been found at three localities in West Bohemia and at one locality in NW Bohemia. It is considered a boreal species rare in Europe and listed as extinct from the Czech Republic. The species is well distinguishable microscopically by the spores which clearly differ from other species with a resupinate, hydnoid basidioma. Remarks on its world distribution are added.
PETERSEN R.H. (1971): A new genus segregated from Kavinia Pilát. Česká Mykologie 25(3): 129-134 (published: 9th July, 1971)
abstract
When Pilát (1938) described Kavinia, the genus was typified by its only species, K. sajanensis Pil. Later, Pilát (see Christiansen, 1953), and Eriksson (1954) agreed that K. sajanensis was identical to Clavaria bourdotii Bresadola (1908), which had been misinterpreted as clavarioid instead of hydnoid. Donk (1956) reported that C. bourdotii was a synonym of Hydnum alboviride Morgan (1887). Gilbertson (1970) finally proposed the combination Kavinia alboviridis (Morgan) Gilbertson, which is assumed to be correct. A second species of resupinate hydnoid fungi was transferred into Kavinia by Eriksson (1958) as K. himantia, based on Hydnum himantia Schweinitz, and variously placed in several resupinate-hydnoid genera. The two species are not congeneric, as suggested by Corner (1970). No long and involved species descriptions are needed, for these have been supplied by the literature. Certain discordant structures might well be pointed out, however, to supply evidence for the separation of the taxa. First, the spores of K. alboviridis are roughened, thick-walled, ovoid to ellipsoid, and with the ornamentation of cyanophilous low warts or crests. The spores of K. himantia are smooth, thin-walled, cylindrical and without cyanophilous reaction to speak of (although the wall itself is weakly so). In short, the spores of K. alboviridis differ from those of K. himantia precisely as the spores of most species of Ramaria differ from those of Lentaria. Second, the hyphae of K. himantia (especially the hyphae of the basal tomentum) bear ampulliform or onion-shaped swellings, especially at the clamped septa. The hyphae of K. alboviridis are without such swellings. Third, the hyphae of K. himantia often are covered with small, cyanophilous, densely distributed spines, while the hyphae of K. alboviridis are smooth.

(2016): Fungi and lichens recorded during the Cryptogam Symposium on Natural Beech Forests, Slovakia 2011. [old-growth beech forests, diversity, conservation, indicator, red-list, Europe] Czech Mycology 68(1): 1-40 (published: 1st February, 2016)
abstract
In September 2011, an international team of cryptogam experts visited seven national nature reserves in five mountain areas of Slovakia: Havešová and Stužica in the Poloniny Mts., Vihorlat in the Vihorlatské vrchy Mts., Oblík in the Slanské vrchy Mts., Dobročský prales and Klenovský Vepor in the Veporské vrchy Mts. and Badínsky prales in the Kremnické vrchy Mts. The reserves were selected to represent examples of the best protected old-growth beech forests in the country. The aim was to study the diversity of wood-inhabiting fungi on fallen beech logs and epiphytic lichens on standing beech trees. In total, 215 fungal species and 128 lichens were recorded on beech wood and bark, and 27 fungi and 26 lichens on additional substrates. The site of the highest conservation value is Stužica with 126 fungi and 79 lichens recorded on beech, of which 12 fungi and 19 lichens are indicators of high nature conservation value. Combined with historical records, a total of 19 non-lichenised fungal indicators are now reported from the site, making it the highest ranked natural beech forest in Europe. The second most important reserve for fungal diversity is Havešová with 121 species, including 14 indicator species recorded on beech wood. For lichens, the second most important reserve is Klenovský Vepor with 69 species including 18 lichen indicators recorded on beech. Nine fungus species are here reported as new to Slovakia: Asterostroma medium, Entoloma hispidulum, E. pseudoparasiticum, Gloeohypochnicium analogum, Hohenbuehelia valesiaca, Hymenochaete ulmicola, Hypocrea parmastoi, Melanomma spiniferum and Scutellinia colensoi. Lichen species Alyxoria ochrocheila is reported as new to Slovakia and Lecanographa amylacea, which was considered extinct in the Slovak Red list, was also recorded. This is the first list of wood-inhabiting fungi and epiphytic lichens of old-growth beech forests in Slovakia, and hence an important contribution to the exploration of biodiversity in Slovakia.
