Lichenes Delicati Exsiccati Editae of little, fine, special lichens is edited in honour of Antonín Vězda (1920–2008). The lichen-forming fungus Santessonia namibensis is included on the occasion of the 95th anniversary of Rolf Santesson, the outstanding Swedish lichenologist’s birth. Bibliographic data of the most important publications concerning to his lichenological carrier is compiled. The second fascicle of the exsiccate is consisted of 15 species and distributed to 12 lichen herbaria of the world.
A new exsiccate, Lichenes Delicati Exsiccati Editae — of little, fine, special lichens and lichenicolous fungi — dedicated to the famous lichenologist Antonín Vězda (1920–2008), is compiled and issued. The lichenicolous fungus
is described from Bolivia and named after him on the occasion of the 90th anniversary of his birth. The first fascicle is consisted of 15 species and distributed to 12 lichen herbaria worldwide (BM, BP, F, hb. Flakus, hb. Kalb, HO, KRAM, PRA-V, SAV, STU, UPS, VBI).
Lichenes Delicati Exsiccati Editae of little, fine, special lichens is edited in honour of Antonín Vězda (1920–2008). The foliicolous lichen Coenogonium usambarense was collected by Tamás Pócs, who contributed also often to Vězda’s exsiccates and celebrated his 80th birthday in 2013. Herpothallon hypoprotocetraricum was also collected in Africa during a field trip organised by him. It represents isotype material. The third fascicle of the exsiccate is consisted of 15 species and distributed to 12 lichen herbaria of the world.
The bibliography of foliicolous lichenised fungi is compiled, listing publications of the last 60 years following Santesson’s world monograph on the foliicolous lichens. It consists of 708 scientific papers, journal publications, books, posters, exsiccates, dissertation manuscripts.
Lichenes Delicati Exsiccati Editae of little, fine, special lichens is edited in honour of Antonín Vězda (1920–2008). The foliicolous lichens Coenogonium seychellense sp. n. and C. subdilucidum sp. n. were collected by Tamás Pócs, Fellhanera stanhopeae by Attila Borhidi, Lyromma dolicobelum of ascosporic state was found by Adam Flakus, Porina applanata by Paulina Bawingan. Other collections originate from the participants of the 20th NLF meeting 2013, Vadstena and surroundings — where Erik Acharius, the “father of lichenology” lived for decades. Several species collected by László Lőkős from Albania, Bulgaria and Montenegro. The fourth fascicle of the exsiccate is consisted of 15 species (including 3 lichenicolous fungi), distributed to 12 lichen herbaria of the world and dedicated to Robert Lücking’s 50th birthday.
Soil biological properties and CO
emission were compared in undisturbed grass and regularly disked rows of a peach plantation. Higher nutrient content and biological activity were found in the undisturbed, grass-covered rows. Significantly higher CO
fluxes were measured in this treatment at almost all the measurement times, in all the soil water content ranges, except the one in which the volumetric soil water content was higher than 45%. The obtained results indicated that in addition to the favourable effect of soil tillage on soil aeration, regular soil disturbance reduces soil microbial activity and soil CO
now represents three almost equally frequent species in Hungary.
Toninia opuntioides, T. physaroides
were investigated in the same locality for comparison of various parameters of their microhabitats. Analysis of variance (ANOVA) was used to test the niche preferences of these species. More than two hundred soil samples were analysed in the respect of six soil parameters. Aspect and slope degree of the microsites, and the abundance of associated bryophyte and lichen species were also studied. ANOVA revealed that there are significant differences between the species in acidity, carbonate content, soil depth, aspect and slope degree.
Sarcopyrenia gibba was discovered as new to Hungary recently. Specimens were collected throughout the country at 11 localities mainly on anthropogenic substrates (concrete, asbestos roof, stone walls, etc.) from 1982. The floristically new species seems to be spreading in Hungary probably due to the effect of urbanisation.
