Calatayud V. & Barreno E. (1995): Lichenicolous fungi from the Iberian peninsula and the Canary Islands II, Flechten Follmann. Contributions Lich., 397-402

Abrothallus parmotrematis and A. welwitschii are reported from the Canary Islands for the first time, and so are Didymetlopsispulposi, Lichenosticta microsticticum, Pronectria leptaleae, and Zwackhiomyces physciicola for the Iberian Peninsula. New host lichens are also dealt with, and taxonomical as well as chorological notes are appended. Read more...

Ohmura Y. (2002): Phylogenetic evaluation of infrageneric groups of the genus Usnea based on ITS regions in rDNA, Journal of the Hattori Botanical Laboratory, 92: 231-243

A phylogenetic tree, inferred from the sequences of ITS regions (including ITS1, 5.8S rDNA and ITS2) of rDNA, has been constructed in order to confirm the infrageneric ranks of the genus Usnea in Japan. Twenty-one species of Usnea mainly collected from Japan were analyzed using the neighbor-joining (NJ) method. Samples were selected from various infrageneric groups of the genus. The data supports the segregation of the subgenera Dolichousnea and Eumitria from sub genus Usnea, and the treatment of … Read more...

Jørgensen P.M. (2002): Further notes on Asian species of the lichen genus Fuscopannaria, Journal of the Hattori Botanical Laboratory, 92: 225-229

Several of the recently described species in the genus Fuscopannaria have proved to have a wider distribution than anticipated: F. coerulescens (Borneo and India), F. dissecta (Borneo, The Philippines), F. saltuensis (India) and F. siamensis (India, Korea). F. dissecta has for the first time been found with ripe spores which are subglobose, in contrast to the ellipsoid ones of F leucosticta. Leioderma sorediatum is reported as new to India and Thailand Read more...

Blanco Y., Blanch M., Fontaniella B., Legaz M.-E., Millanes A.M., Pereira E.C. & Vicente C. (2002): Bioproduction of lichen phenolics by immobilized lichen cells with emphasis on the role of epiphytic bacteria, Journal of the Hattori Botanical Laboratory, 92: 245-260

Since 1966, immobilization of lichen cells or enzymes in inert, hydrophilic matrices by adsorption or entrapment is the usual method to improve the production of lichen metabolites without biomass destruction. Alginate and polyacrylamide are used for cell entrapment, whereas bioskin, clays or polyhydroxyurethane have been largely preferred as matrices for immobilization by adsorp tion. Entrapped or adsorbed cells can be used to induce a particular metabolic transformation, i.e., lecanoric acid into … Read more...

Yamamoto Y., Takahagi T., Sato F., Kinoshita Y., Nakashima H. & Yoshimura I. (2001): Screening of halophilic or salt tolerant lichen mycobionts cultured on sodium chloride enriched media, Journal of the Hattori Botanical Laboratory, 90: 307-314

Halophilic or salt tolerant lichen mycobionts were screened for 77 species on an NaCl enriched medium. Only the Niebla homalea mycobiont collected from the North American Pacific seashore showed evident halophilic growth: 145% growth on malt-yeast extract agar-medium supple mented with 0.9 m NaCl and 129% growth at 1.2 m NaCl in comparison with that of the zero NaCl medium. In addition, mycobionts ofArthonia cinnabarina, Chaenotheca brunneola, Caloplaca scop- ularis, Ramalina subbreviuscula and Vermilacinia … Read more...

Ohmura Y. & Kashiwadani H. (2001): Taxonomic study of the genus Usnea (lichenized Ascomycetes) in Japan and Taiwan, Journal of the Hattori Botanical Laboratory, 90: 35065

The genus Usnea is taxonomically revised, resulting in 43 species for Japan and Taiwan. It consists of three subgenera, Usnea, Eumitria (Stirt.) Zahlbr. and Dolichousnea Y. Ohmura, and two sections in the subgenus Usnea, Usnea and Ceratinae (Motyka) Y. Ohmura. Among the species listed in the present study, U. dendritica Stirt., U. hesperina Motyka, U. nidifica Taylor, U. sinensis Motyka and U. trichodeoides Vain, are reported as new to Japan and Taiwan. Usnea pygmoidea, formerly placed under the … Read more...

Follmann G. & Peine J. (2001): An integrated key to, and a critical survey of the South American representatives of the lichen family Roccellaceae (Arthoniales), Journal of the Hattori Botanical Laboratory, 90: 251-267

South America with half of all the known species represents most probably the primary diversity centre of the ascolocular lichen family Roccellaceae (Arthoniales). Nevertheless, neither a modem identification key nor a topical survey are available for the biologically, ecologically and phy- logenetically interesting taxa occurring on the mainland and (or) the adjacent islands. A computer- aided, dichotomous key has therefore been prepared, based as far as possible on easily detectable characters. … Read more...

Czeczuga B. & Krukowska K. (2001): Effect of habitat conditions on phycobionts and the content of photosynthesising pigments in five lichen species, Journal of the Hattori Botanical Laboratory, 90: 293-305

The effect of habitat conditions on the size and number of phycobiont cells, on the con tent of chlorophylls and carotenoids in the thalli of Cetraria islandica, Cladina arbuscula, Hypogym- nia physodes, Parmelia sulcata and Peltigera rufescens were investigated. Seasonal differences were found in the size of phycobiont cells. The mean size of algal cells increases from February to Octo ber, the smallest were observed in the winter. Lichen species collected from the sites distant from town were characterised … Read more...

Aptroot A. & Sipman H.J.M. (2001): New Hong Kong lichens, ascomycetes and lichenicolous fungi, Journal of the Hattori Botanical Laboratory, 91: 317-343

Numerous collections representing 183 species of lichens, ascomycetes and licheni- colous fungi are reported from gatherings made in Hong Kong in July 2000, mainly on Lantau Island. These include 9 species which are described here as new to science: the lichenized ascomycetes Ani- someridium tetrasporum, Biatorella saxicola, Ocellularia palaeoamplior, Ramalina seawardii, Ra- malina throwerae, the non-lichenized corticolous ascomycete Granulopyrenis seawardii, the licheni- colous ascomycete Obryzam … Read more...
