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.
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.
