Follmann G., Schulz M. & Werner B. (1998): On the identity and position of Pentagenella fragillima, Roccellodea nigerrima, and some related species (Roccellaceae, Opegraphales), Journal of the Hattori Botanical Laboratory, 85: 245-265

Pentagenella fragillima was described from Chile by Darbishire (1897) and Roccellodea nigerrima from the Galapagos Islands by the same author (1932). Because of apparently missing type material, both Roccellaceae were excluded from a cladistical treatment of the family as critical taxa of uncertain position by Tehler (1990), and Weber (1986) listed the second one under “Rejected reports, synonyms, and misapplied names” in his catalogue of Galapagos lichens. On the other side, lichen samples corresponding … Read more...

Czeczuga B. & Christensen S.N. (1998): Carotenoids in thalli of Cladonia portentosa from the Danish Wadden Sea Island of Fano, Journal of the Hattori Botanical Laboratory, 84: 297-308

Column and thin-layer chromatography revealed the presence of the following carotenoids in the thalli of 72 specimens of Cladonia portentosa from various dune habitats on the Danish Wadden Sea island of Fane: ∝-carotene, ß-carotene, ß-cryptoxanthin, zeaxanthin, lutein, lycopene-5,6-epoxide, antheraxanthin, lutein epoxide, violaxanthin, neoxanthin, hydroxyechinenone, adonixanthin, canthaxanthin, astaxanthin. capsochrome and apo-6'- lycopenal. The total content of carotenoids ranged from 12.05 … Read more...

Csintalan Z., Takács Z., Proctor M.C.F., Lichtenthaler H.K. & Tuba Z. (1998): Desiccation and rehydration responses of desiccation tolerant moss and lichen species from a temperate semidesert grassland, Journal of the Hattori Botanical Laboratory, 84: 71-80

C02 exchange (C02 assimilation, dark respiration), potential photochemical activity and blue and red fluorescence ratios (F450/F690, F690/F735) of the desiccation-tolerant (DT) ectohydric moss (Tortula ruralis) and two DT lichens (Cladonia convoluta and C. furcata) from a temperate semidesert grassland during desiccation and rehydration are reported. Optimal water content for car bon fixation (RWC = 100%) was less than 50% of the saturation water content in all investigated species. The water-content … Read more...

Hammer S. (1996): Cladonia biogeography in Pacific areas of the United States, Journal of the Hattori Botanical Laboratory, 80: 307-322

The biogeography of 58 taxa in the lichen genus Cladonia reflects two major distributional trends in Pacific areas of the western United States. One trend includes species that are oceanic. Many of these species are found primarily or exclusively west of the Cascade Mountains, and are endemic to the western United States. This species assemblage, particularly south of the California-Oregon border, is isolated from more northerly populations. Like the vascular plant flora, it has experienced increased … Read more...

Bychek I.A., Bychek E.A. & Baybulatova N.E. (1996): Polar and neutral lipids in some lichens from Issyk-kul and Baikal Regions, Journal of the Hattori Botanical Laboratory, 79: 99-106

Ten liehen species from the foothills of Kungey-Alatau mountain range, Issyk-Kul region (August 1992), and nine lichen species from Baikal region, Bolshiye Kotye biostation (July 1992), were analyzed for total lipid contents and correlation of the general lipid classes: neutral lipid (NL), glycolipids (GL) and phospholipids (PL). Individual constituents of NL, GL and PL were also investigated. Examination of NLs by method of thin-layer chromato graphy showed the domination of triacylglycerols, free … Read more...

Blanchon D.J., Braggins J.E. & Stewart A. (1996): The lichen genus Ramalina in New Zealand, Journal of the Hattori Botanical Laboratory, 79: 43-98

The New Zealand members of the lichen genus Ramalina Ach. have been revised on the basis of morphological characters, internal anatomy and chemical information from thallus colour tests and thin-layer chromatography. More than 1900 herbarium specimens from New Zealand herbaria and personal collections have been studied and relabelled where necessary. Eighteen taxa are recognised for New Zealand, including the ten species listed by Galloway (1992), three new species (Ramalina erumpens, R. inflexa … Read more...

Moberg R. (1994): Is the Pacific an area of speciation for some foliose genera of the lichen family Physciaceae?, Journal of the Hattori Botanical Laboratory, 76: 173-181

Speciation in lichens is poorly known, as the nature of the sexual reproduction is equivocal and there is no support from fossil lichens. Using examples from the Physciaceae, criteria for speciation in lichens are discussed. Some of the genera are well-developed in the Pacific, and for Phaeophyscia the taxonomy and world distribution is presented and correlated with presumed speciation processes. The genus Physconia, which is represented by a larger number of species in the northern Pacific than … Read more...

Mattsson J.-E. (1994): Lichen proteins, secondary products and morphology: a review of protein studies in lichens with special emphasis on taxonomy, Journal of the Hattori Botanical Laboratory, 76: 235-248

Almost 30 protein studies with different objectives for c. 50 lichens species are compared and the taxonomic relevance, in particular, and other aspects of the use of elec trophoretic techniques discussed. The results indicate large enzymatic variation both in vegetat- ively and sexually propagating lichens, differences in enzyme patterns between lichenized and non-lichenized bionts but also, correlation between protein banding patterns and secondary product chemistry or spatial separation.

Kärnefelt E.I. & Thell A. (1994): Sexual reproductive characters vs. morphological characters in lichen genera, Journal of the Hattori Botanical Laboratory, 76: 207-219

The generic concept and its early historical development until today’s more natural multi-character based concept is discussed. The modern generic concept for lichenized ascomy- cetes has traditionally been slightly different concerning crustose groups on the one hand and foliose and fruticose groups on the other. More studies of sexual reproductive structures in the large groups of lichens should presumably be carried out since it has been demonstrated recently that a considerable variation actually … Read more...

Jørgensen P.M. (1994): Studies in the lichen family Pannariaceae VI: the taxonomy and phytogeography of Pannaria Del. s. lat, Journal of the Hattori Botanical Laboratory, 76: 197-206

The genus Pannaria as presently understood is shown to be not homogeneous. It is divided in two genera: (1) Pannaria s. str., a tropical to warm-temperate, mostly foliose genus with no amyloid, apical structures in the asci, containing pannarin and related substances; it is further divided into three subgenera, of which subgenus Chryopannaria is newly described. (2) Fuscopannaria gen. nov., a temperate to arctic-alpine, mostly small-squamulose genus with amyloid apical structures in the asci, containing … Read more...
