Porosty cynkowo-ołowiowych terenów pogórniczych w Jaworznie

The paper presents the occurrence of 69 lichen species in calamine areas in Jaworzno town, including 47 taxa in the Ciężkowice area, 32 in Długoszyn and 38 in Sadowa Góra. Six lichen species are red-listed in Poland. Rare species characteristic of zinc- and lead-enriched substrates were found: Agonimia vouauxii, Diploschistes muscorum, Sarcosagium campestre, Vezdaea aestivalis and V. leprosa.

The unusual lichens and allied fungi of Sandbanks Provincial Park, Ontario

Sandbanks Provincial Park contains one of the world’s largest freshwater bay mouth sandbar and dune systems. To better understand the lichen biota of this provincially rare ecosystem, we inventoried the species at Sandbanks and its surrounding area. We found 128 species of lichens and allied fungi in 58 genera. Two species are new to Canada, Hyperphyscia syncolla (Tuck. ex Nyl.) Kalb and Minutoexcipula mariana V. Atienza. One additional species is new to Ontario, Physcia biziana (A. Massal.) Zahlbr. Sixteen species are provincially ranked as S1 (critically imperiled), S2 (imperiled), or S3 (vulnerable) by the Natural Heritage Information Centre: Acrocordia cavata (Ach.) R.C. Harris, Anaptychia crinalis (Schaer.) Vězda, Arthrosporum populorum A. Massal., Bacidia rubella (Hoffm.) A. Massal., Cresponea chloroconia (Tuck.) Egea & Torrente, Diploschistes muscorum (Scop.) R. Sant. ssp. muscorum, Flavopunctelia soredica (Nyl.) Hale, Heterodermia obscurata (Nyl.) Trevis., Lecanora carlottiana Lewis & Śliwa, Leptogium tenuissimum (Dicks.) Körb., Phaeophyscia hirsuta (Mereschk.) Essl., Physconia enteroxantha (Nyl.) Poelt, Ramalina pollinaria (Westr.) Ach., Staurothele drummondii (Tuck.) Tuck., Teloschistes chrysophthalmus (L.) Th. Fr., and Trypethelium virens Tuck. ex Michener. Unranked species collected for the second time in Ontario are Arthonia diffusa Nyl., Cladonia norvegica Tønsberg & Holien, and Lecanora juniperina Śliwa. Other provincially rare and unranked species are Caloplaca pollinii (A. Massal.) Jatta and Xanthomendoza weberi (S. Kondr. & Kärnefelt) L. Lindblom. Of these rare and unranked species, the following are reported (published) for the first time in the province: A. diffusa, C. pollinii, and L. juniperina. Some lichens require specific ecological conditions for colonization, and the rare ecosystem at Sandbanks appears to be the reason for the large number of rare species. We recommend a lichen education program for park visitors to make them more aware of these unusually rare and sensitive lichens in the park.

Lichens of abandoned zinc-lead mines

A list of lichens from areas of zinc-lead ores in Southern Poland and a review of the characteristic lichen biota of these sites is provided. In spite of the devastated and heavy metal contaminated environment, a highly diverse epigeic and epilithic lichen biota was found, including species characteristic of various anthropogenic habitats, particularly zinc and lead enriched substrates (<em>Diploschistes muscorum, Steinia geophana, Sarcosagium campestre, Vezdaea aestivalis</em> and <em>V. leprosa</em>). Also, the high-mountain species <em>Leucocarpia biatorella</em>, as well as very rare in Europe <em>Thelocarpon imperceptum</em>, and several species categorized as very rare, endangered and protected in Poland were recorded. Crustose lichens are the most abundant; among fruticose forms <em>Cladonia</em> spp. predominate and <em>Stereocaulon incrustatum</em> is common.

Thallus Development and Phycobionts of the Parasitic Lichen Diploschistes Muscorum

The lichen Diploschistes muscorum (Scop.)R.Sant. starts its thallus development as a parasite of the squamules of different Cladonia species, but fully developed Diploschistes thalli live independently. D. muscorum develops apothecia in the Cladonia squamules and is associated at that stage with the phycobiont of Cladonia, Trebouxia irregularis. Augmentation of the Cladonia phycobiont and growth of the D. muscorum hyphae result in a development of young Diploschistes thalli from the Cladonia squamules. As the Cladonia increasingly disintegrates, D. muscorum becomes independent. In fully developed thalli the Cladonia phycobiont can be exchanged for T. showmanii, an alga different in morphology and reproduction from T. irregularis. In one case, a fully developed D. muscorum thallus with both phycobionts was demonstrated. A fully established thallus can also be formed by the growth of small thallus swellings, which cover Cladonia squamules.

NOWE STANOWISKO DIPLOSCHISTES MUSCORUM (Scop.) R. Sant. na NIZINIE WIELKOPOLSKO-KUJAWSKIEJ

Diploschistes muscorum (Scop.) R. Sant. has been found in the southern part of the Wielkopolsko-Kujawska Lowland. So far, in western and central Poland the species has been reported in few localities.
