Squamarina scopulorum (Lecanoraceae), a new lichen species from Norway

The new species Squamarina scopulorum Haugan & Timdal (sect. Petroplaca ) is described from Norway. It differs from the sympatric and morphologically closely similar species S. magnussonii and S. pachylepidea mainly in the color of the apothecial disc and in the thallus chemistry. The delimitation of the genus Squamarina and the family Squamarinaceae are briefly discussed.     

Studies in species of the lichen genus Asahinea

Asahinia kurodakensis is shown to be conspecific with A. scholanderi. Cetraria saviczii var. Candida and A. culbersoniorum (nom. inval.), are only chemical strain of A. chrysantha , lacking usnic acid.     

Three new species in the lichen genus Ionaspis

Ionaspis fuegensis, I. granvina and I. ventosa are described. The genus is recorded for the first time with certainty from the cool-temperate Southern Hemisphere. I. granvina differs from all other species in its carbonaceous black exciple and I. ventosa in its ecology: windswept mountain summits.     

New data on the lichen genus Punctelia (Parmeliaceae)

Punctelia constantimontium Sérusiaux, a species present in South America and in southern Africa, is described as new. Punctelia riograndensis is reported for the first time for Africa.     

Chemosyndromes in the lichen genus Teloschistes (Teloschistaceae, Lecanorales)

The secondary metabolites of 150 specimens belonging to 29 species of Teloschistes were analysed with HPLC. Seven anthraquinones were detected of which parietin dominated with minor proportions of emodin, teloschistin, fallacinal and parietinic acid. The depsidones vicanicin, caloploicin, and isofulgidin occurred together with some compounds of unknown identity in varying proportions in T. flavicans, T. peruensis, T. stellatus, and one unnamed taxon. Nine chemosyndromes were found in the genus. Most species had only one chemosyndrome, but T. flavicans s. lat. had six syndromes. The geographical distribution patterns of these chemosyndromes in T. flavicans are discussed as well as the applicability of chemical characters for species delimitation in Teloschistes.     

Two new species in the lichen genus Szczawinskia A. Funk

Szczawinskia leucopoda Holien & Tønsberg and S. foliicola Holien & Tønsberg are described from coastal Central Norway and Newfoundland, and from Papua New Guinea, respectively.     

The lichen genus Heterodermia (Physciaceae) in South America – a contribution including five new species

Thirty‐three species of the lichen genus Heterodermia in South America, mainly from Ecuador and Peru, are defined. Morphology, anatomy, chemistry, habitat, distribution and interrelation between the species are discussed. A key to the treated species is presented. Five species are described as new; Heterodermia andina, H. arvidssonii, H. badia, H. fertilis and H. parva. One new combination is proposed; H. spinigera. Two species are reported as new to South America, H. spathulifera and H subcitrina, and H. palpebrata is reported as new to USA.     

Remarks on Aspicilia parasitica (Lecanoraceae, Lichenes)

Loppi, S. & Mariotti, M. G. 1995. — Remarks on Aspicilia parasitica (Lecanoraceae, Lichenes). — Nord. J. Bot. 15: 557–559. Copenhagen. ISSN 0107–055X.
Morphology and distribution of Aspicilia parasitica B. de Lesd., a much neglected species, are discussed. Since the holotype has been lost, a lectotype was selected. Examination of the latter and other specimens showed that the diagnostic characters are quite constant. All of known stations of A. parasitica are in the central-eastem Mediterranean area and include Italy, Algeria, Greece and Bulgaria.     

The lichen genus Erioderma (Pannariaceae) in Ecuador and neighbouring countries

The lichen genus Erioderma is shown to be particularly species-rich in Ecuador, especially in the upper cloud forest (3000–3400m). Altogether seventeen species are recorded of which the following are new: E. barbellatum, E. cyathophorum, E. divisum, E. gloriosum, E. papyraceum, E. pycnidiferum, E. sinuatum , most of which also occur in the neighbouring countries. Two further taxa from these are described as new: E. latilobatum from Bolivia and E. peruvianum from Peru and Bolivia.     

Two new species of the genus Coccoloba (Polygonaceae)

Coccoloba ecuadorensis sp. nov, a large-leaved species from the humid coastal forest of Northwestern Ecuador, and C. trollii sp. nov., a small-leaved species from an isolated patch of dry forest in central Bolivia are described.     

假球壳科Comoclathris属一新种（英文）

为了建立具砖格状子囊孢子的座囊菌进化关系并解决其多系群的问题,我们通过多基因系统发育分析的方法探讨了其自然的分类系统。本文描述了具有砖格状子囊孢子的一个新种Comoclathris lini。采用LSU、SSU和ITS序列进行的多基因联合分析表明,所有的Comoclathris属菌株聚在同一单系进化支上,其中包括了由C.lini新种菌株组成的单独分支。文中为新种提供了图示,并与Comoclathris属其他种及多孢子菌属各种进行了比较。     

Three new species of the genus Iriplaris (Polygonaceae)

Three species, Triplaris dugandii Brandbyge, T. moyobambensis Brandbyge, and T. physocalyx Brandbyge, all from lowland Amazonian South America are described as new to science.     

A new species of the genus Torilis Adanson (Apiaceae)

JURY, S. L., 1987. A new species of the genus Torilis Adanson (Apiaceae). The name Torilis nodosa (L.) Gaertner has been shown to have been used to include two very distinct variants. Torilis nodosa is therefore typified, and the other variant described as a new species.     

New species of the genus Trichodrilus (Oligochaeta, Lumbriculidae)

Five new species of the genus Trichodrilus are described: Trichodrilus longipenis. sp. n. T: rouchi sp. n. T. capilliformis sp. n. and T. angelieri sp. n. from hyporhcic waters of the Iberian Peninsula and France. and T. bonheurensis sp. n. from superticial waters of France. The new taxa contribute with some new features to an amended diagnosis of the genus: presence of modified penial setae, four pairs of spermathecae, hair-like dorsal setae and glandular pads in the epidermis.     

New species of the genus Epistephium (Orchidaceae, Vanilloideae)

The morphological study of the herbarium material representing Epistephium (Orchidaceae, Vanilloideae) led to the discovery of two groups of specimens that significantly differ from all known species of the genus. The results of literature data study and of comparative analysis of those and other specimens suggest that these collections represent new taxa that we describe as E. garayi and E. kubiyuense. The distinguishing features of the species are indicated. As both new species are reported from Colombia (E. garayi, also from Guyana), the key for the determination of all Colombian representatives of the genus is included. Information on the ecology and distribution of newly described taxa is presented.
