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.

RAMSHAJ Q., RUSEVSKA K., TOFILOVSKA S., KARADELEV M. (2021): Checklist of macrofungi from oak forests in the Republic of Kosovo.   [fungi, taxa, Balkan Peninsula, diversity, ecology, rare species.]  Czech Mycology 73(1): 21-42   (published: 12th February, 2021)   Electronic supplement
  abstract   In the period from 2017 to 2019 a survey of the diversity of fungi in oak forests in the Republic of Kosovo was conducted. The survey included 31 localities, mainly in Quercetum frainetto-cerris and Querco-Carpinetum orientalis communities. As a result of the fieldwork performed in various seasons, a first checklist of fungi from oak forests in the country is provided. A total of 220 taxa (219 species and one forma) were identified. The majority of the identified taxa belong to Basidiomycota (206) and only 14 species to Ascomycota. The paper provides a list of all recorded species with data on locality, altitude, time of collection, forest association and type of substrate. Distribution and ecology of selected rare or threatened species are briefly discussed.

HOLEC J., BĚŤÁK J., DVOŘÁK D., KŘÍŽ M., KUCHAŘÍKOVÁ M., KRZYŚCIAK-KOSIŃSKA R., KUČERA T. (2019): Macrofungi on fallen oak trunks in the Białowieża Virgin Forest – ecological role of trunk parameters and surrounding vegetation.   [lignicolous fungi, Quercus robur, Europe, fungal diversity, ecology, wood decay, trunk orientation, forest canopy gaps, heat load.]  Czech Mycology 71(1): 65-89   (published: 18th June, 2019)   Electronic supplement
  abstract   All groups of macrofungi were recorded on 32 large fallen trunks of pedunculate oak (Quercus robur) in various decay stages in the strictly protected zone of Białowieża National Park, Poland. The total number of species was 187 with 4–38 species per trunk. The mycobiota of individual trunks was unique, consisting of a variable set of several frequent species, a high number of infrequent to rare ones, and a considerable proportion of mycorrhizal fungi and species preferring conifer wood. Relations between trunk parameters, surrounding vegetation and fungal occurrences were analysed using multivariate statistical methods. The number of fungal species per trunk was significantly correlated with trunk orientation, which reflects the heat load via forest canopy gap, trunk size parameters, percentage of bark cover and contact with the soil. The species-richest trunks were those covered by bark, of larger volume (thick, long), not exposed to heat from afternoon sun, but, simultaneously, with lower canopy cover. Orientation (azimuth) of the fallen trunks proved to be significant also for the fungal species composition of a particular trunk, which also reflected trunk size characteristics, its moss/bark cover and contact with the soil. Presence of some dominants (Ganoderma applanatum, Mycena inclinata, Kretzschmaria deusta, Xylobolus frustulatus) had a significant effect on fungal community composition. Some herbs requiring nutrient-rich soils occurred in the vicinity of trunks with a larger contact area with the soil and in later stages of decay. The process of oak trunk decay in relation to fungi and surrounding vegetation is outlined.

KUBIČKA J. (1972): Beitrag zur Kenntnis der mykoflora des Tales Zadielská dolina in dem Südslovakischen Karstgebeit. I. Lamprospora lutziana Boud.  Česká Mykologie 26(1): 37-42   (published: 1972)
  abstract   Report on the first record of the operculate discomycete Lamprospora lutziana Boud. in the Zadielská dolina in the South Slovak Karst. This is the first record in Czechoslovakia and perhaps the second in the world. The fungus was found growing in thousands of fruit bodies on moss-covered calcareous stones in the stream of the valley. A discussion of the genus Lamprospora and the erection of a new section: sect. Ovalisporae Kubička. Lamprospora lutziana appears to be muscicolous, calciphilous and hygrophilous.

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.

PILÁT A. (1968): Diversity and phylogenetic position of the Thelephoraceae sensu amplissimo.  Česká Mykologie 22(4): 247-258   (published: 1968)
  abstract   The family of fungi Thelephoraceae in the system of Fries and other older authors is seemingly well-organized, and if it were not for the large number of species, it would be easy to navigate, as earlier mycologists believed. In the early 20th century, however, it became clear that this is a highly heterogeneous group, and that neither the content of the family nor the delimitations of the genera are sustainable, since they combine unrelated elements on the basis of superficial morphological similarities that are evolutionarily insignificant. The study of Thelephoraceae sensu amplissimo and its phylogeny-based classification was advanced by many mycologists including P.A. Karsten, V. Fayod, N. Patouillard, V. Litschauer, E.M. Wakefield, E.A. Burt, S. Lundell, H. Bourdot, G.H. Cunningham, M.A. Donk, P.D. Rogers, H.S. Jackson, R. Singer, J. Boidin, G.W. Martin, L.S. Olive, P.H. Talbot, P.L. Lentz, J. Eriksson, M. Svrček, D.A. Reid, E. Parmasto, A.E. Liberta, among others. There is no doubt that the group includes the origins of nearly all eubasidiomycetes and also various branches of Auriculariales and Tremellales. This complicates classification to such a degree that no two systematic works use the same system, and this state of taxonomic chaos is expected to persist.
