    Notes: Abstract The recently discovered La Pacana caldera, 60 × 35 km, is the largest caldera yet described in South America. This resurgent caldera of Pliocene age developed in a continental platemargin environment in a major province of ignimbrite volcanism in the Central Andes of northern Chile at about 23° S latitude. Collapse of La Pacana caldera was initiated by the eruption of about 900 km3 of the rhyodacitic Atana Ignimbrite. The Atana Ignimbrite was erupted from a composite ring fracture system and formed at least four major ash-flow tuff units that are separated locally by thin air-fall and surge deposits; all four sheets were emplaced in rapid succession about 4.1 ± 0.4 Ma ago. Caldera collapse was followed closely by resurgent doming of the caldera floor, accompanied by early postcaldera eruptions of dacitic to rhyolitic lava domes along the ring fractures. The resurgent dome is an elongated, asymmetrical uplift, 48.5 × 12 km, which is broken by a complex system of normal faults locally forming a narrow discontinuous apical graben. Later, postcaldera eruptions produced large andesitic and dacitic stratocones along the caldera margins and dacitic domes on the resurgent dome beginning about 3.5 Ma ago and persisting into the Quaternary. Hydrothermally altered rocks occur in the eroded cores of precaldera and postcaldera stratovolcanoes and along fractures in the resurgent dome, but no ore deposits are known. A few warm springs located in salars within the caldera moat appear to be vestiges of the caldera geothermal system.

    Notes: Abstract A new species of Penicillium Link ex Fries is described and illustrated. A single strain was recovered from forest soil in northern Thailand. It clearly differs from all species of the genus described so far and is, therefore, described and proposed as a new taxon: Penicillium siamense sp. nov.

    Notes: Abstract After a thourough revision carried out by the author on yeasts isolated from decayed wood in the evergreen rainy Valdivian forest of southern Chile, that were described previously as new species [1–10], very important errors were found that had slipped into them, due to an unfortunate and unexpected technical failure. Thence, the necessity of a full emendation. Ten of them were found to by synonymous with others. And ten have been maintained as new species and are presented here with amended Latin diagnoses.

    Notes: Abstract A complete inhibition of germination and conidiation was observed inNeurospora sitophila when maintained under a pure carbon dioxide atmosphere. Experiments were performed to explain the relatively poor conidiation of this species of mold under standard laboratory experimental conditions.

    Notes: Abstract The transport characteristics of immunoisolation membranes can have a critical effect on the design of hybrid artificial organs and cell therapies. However, it has been difficult to quantitatively evaluate the desired transport properties of different hollow fiber membranes due to bulk mass transfer limitations in the fiber lumen and annular space. An attractive alternative to existing methodologies is to use the rate of solute removal or “washout” from the annular space during constant flow perfusion through the fiber lumen. Experimental washout curves were obtained for glucose and a 10 kD dextran in two different hollow fiber devices. Data were analyzed using a theoretical model which accounts for convective and diffusive transport in the lumen, membrane, and annular space. The model was in good agreement with the experimental results and provided an accurate measure of the effective membrane diffusion coefficient for both small and large solutes. This approach should prove useful in theoretical analyses of solute transport and performance of hollow fiber artificial organs. © 1998 Biomedical Engineering Society. PAC98: 8722Fy, 8790+y

    Notes: Abstract Two strains of an undescribedCandida species were isolated from samples of a rotting trunk ofDrimys winteri collected on the isle of Chiloé in South Chile. A description of the new speciesCandida lignophila is given and its relationship to other species is discussed with particular emphasis on its typical basidiomycetous properties as well as on its ecological habitat.

    Description / Table of Contents: Zusammenfassung Die Wirkung der Inhibition eines vomB. subtilis isolierten Antibiotiks wurde untersucht anC. albicans, C. clausenii, C. langeronii, C. stellatoides, undC. viswanathii als ein mögliches Mittel für die schnelle Bestimmung vonC. albicans. Wachstumsinhibition vonC. albicans durch das Antibiotik war beobachtet, wenn die Hefe an Maltose-Schrägagar vorher inokuliert, bei 30° C für 24 Std., und nachher für Antibiosis an Sabouraud Agarplatten untersucht worden ist. Keine Inhibitionswirkung konnte mitC. clausenii, C. langeronii, C. stellatoides undC. viswanathii unter den selben experimentellen Bedingungen beobachtet werden. Die Ergebnisse sind durch diejenigen vonPérez-Silva &Gil-Alvarez (1960) unterstützt, in denen 33 Stämme vonC. albicans gegen das Antibiotik getested und gezeigt worden sind, daß nurC. albicans die einzige empfindliche Hefe unter 68 Stämmen von Hefen verschiedener Arten war.
    Notes: Abstract The inhibitory action of an antibiotic isolated fromB. subtilis is studied onC. albicans, C. clausenii, C. langeronii, C. stellatoidea, andC. visvanathii, as a possible means forC. albicans rapid identification. Growth inhibition ofC. albicans by the antibiotic was observed when the yeast was preincubated on malt-agar slants, at 30° C, during 24 hours, and tested afterwards for antibiosis on Sabouraud-agar plates. No growth inhibition could be detected withC. clausenii, C. langeronii, C. stellatoidea, andC. viswanathii, under the same experimental conditions. In support of our results are the data reported byPérez-Silva &Gil-Alvarez (1960), where 33 strains ofC. albicans tested against that antibiotic, were shown to be the only sensitive yeast amongst 68 strains of yeast from several species.

    Notes: Abstract An undescribed species of Penicillium was isolated in August 1982 from sand dunes located at the Arches National Monument, Utah, USA. It clearly differs from all species of the genus described so far and is, therefore, described and proposed as a new taxon: Penicillium flavido-stipitatum sp. nov.

    Notes: Abstract Trichosporonoides australiense sp. nov.: a basidiomycetous yeast-like fungus is described and illustrated with information on some physiological characteristics based on a single strain isolated from sweetened orange/mango in Australia. The differences between it and already described members of the genus are discussed. The new species may be distinguished principally by its inability to ferment sucrose and maltose. A dichotomous key to all described members of the genus is provided.

    Notes: Abstract A new species of Penicillium Link ex Fries is described and illustrated. It is represented by twenty six isolates recovered from soil at twenty six different locations at the southern part of the Paul Kruger National Park in South Africa. It clearly differs from all species of the genus described so far among the Biverticillata-Symmetrica Section, and it is therefore described and proposed as a new taxon: Penicillium krugerii sp. nov.
