Larger foraminifera and associated fauna from the Maastrichtian of the southern valencian Prebaetic sector (E Iberian Peninsula) The benthic foraminiferal assemblage and the associated fauna found in the Upper Cretaceous deposits of the Serra de la Solana, Valencia (Spain) have been revised. The study has allowed us to confirm the presence of the foraminiferal species Hellenocyclina beotica Reichel, Siderolites aff. calcitrapoides Lamarck, Orbitoides apiculata Schlumberger, Orbitoides gensacicus (Leymerie) and Omphalocyclus macroporus (Lamarck), as stated by previous authors. In addition, the revision has permitted to identify some other species, never cited before in Serra de la Solana and neighbour regions in Iberian Peninsula, such as Fissoelphidium operculiferum Smout and Selimina cf. spinalis Inan and two different morphotypes of rotaliids that we have left in open nomenclature, namely, Rotaliidae indet. sp. 1 and Rotaliidae indet. sp. 2. The rudists and echinoid found associated to these benthic foraminifera have been also revised. The rudist species found are Hippurites radiosus Des Moulins, Hippurites cornucopiae Defrance, Hippurites cf. lamarcki Douvillé, and Apricardia sp., the two latter cited in Serra de la Solana for the first time. The echinoid assemblage is composed of the species Pygopyrina darderi (Lambert), Linthia payeni (Coquand) and Hemipneustes striatoradiatus (Leske). The whole assemblage, typical of shallow-water platform environments, is Upper Maastrichtian in age and shows some differences in respect other contemporaneous asseblages from other paleogeographical areas.

The scientific outcome of the 2nd Meeting of the Iberian Mycological Society, held in Cerler (Huesca, Spain), is presented here. After conducting fieldwork in 8 localities 949 georeferenced records of fungi belonging to at least 545 species were generated. One hundred and four species are reported for the first time for Aragon, whereas two, Agaricus moelleroides and Hygrophorus hedrychii are reported for the first time in Spain, and 15 taxa represent novelties for the Iberian Peninsula. Furthermore, during the meeting material belonging to 11 new to science species was collected, which are at different stages of investigation. Two of these, Entoloma “stenocystis” and Mycetinis “gramineus” are proposed provisionally here as new, albeit further material of them needs to be found for a formal description. The amount and interest of the results presented here, obtained after conducting fieldwork during only three days substantiates the idea that this kind of events contribute significantly to the knowledge of the mycological flora of different areas of our territory.

Español.  Se da a conocer el número cromosómico de 10 taxones del género Centaurea pertenecientes a la sección Seridia (Juss.) DC. presentes en la Península Ibérica. En el caso de Centaurea lusitanica var. crassifolia P. Silva, C. aspera subsp. stenophylla (Dufour) Nyman y C. barrasii Pau se trata, al parecer, del primer recuento. El número diploide 2n = 22 es el más frecuente en el grupo estudiado, mientras que el nivel tetraploide 2n = 44 sólo se ha detectado en C. seridis L. y C. sphaerocephala L.English. A karyological study of taxa of genus Centaurea L. sect. Seridia (Juss.) DC. in the Iberian Peninsula is reported. We have studied 10 taxa and the reports for 3 of them are given for the first time: Centaurea lusitanica var. crassifolia P. Silva, C. aspera subsp. stenophylla (Dufour) Nyman and C. barrasii Pau. Diploid number 2n = 22 is the most frequent whereas tetraploid level 2n = 44 has been found only in C. seridis L. and C. sphaerocephala L.

Se cita por primera vez en la provincia de Alicante (península ibérica) la especie de planaria terrestre exótica Bipalium cf. kewense Moseley, 1878. Con esta presencia aumenta el área de distribución de la especie en la Comunidad Valenciana, siendo la más meridional. Dado que la especie está considerada en esta comunidad autónoma como especie exótica invasora, se valora el riesgo potencial de colonización de ambientes naturales limítrofes a la zona de observación (jardín privado en zona urbanizada). The non-indigenous terrestrial flatworm Bipalium cf. kewense Moseley, 1878 is reported in Alicante province (Iberian Peninsula) for the first time. This occurrence is the most meridional from the Comunidad Valenciana, enlarging its distribution in this area. As the species is considered an invasive alien species in this region, the potential risk of colonizing natural environments closer to the observation area is evaluated.

Sedimentological studies of the Cretaceous limestones in the central Ionian basin (Amfilochia, Arta as well as Kerasonas areas) indicate that these deposits are composed of calciturbidites interbedded with breccia-microbreccia deposits. In the Amfilochia new cross-section, with a NNW-SSE direction, the lower Cretaceous Vigla limestones and Vigla shales were outcropped for the first time. This section is directed parallel to the paleo Ionian basin axis and the fact of the lateral discontinuity of Vigla limestones and Vigla shales indicate that during the sedimentation of these two Formations there was a restriction along the paleo basin axis, probably due to synsedimentary transfer fault activity. Forty-two (42) samples from Vigla shales were analyzed for their content in CaCO3 and TOC, showed that these sediments present poor to fair hydrocarbon potential. In the Arta new cross-section, with a NE-SW direction, the Upper Cretaceous Senonian deposits showed strong deformation that took place during the compressional regime that affected the Ionian basin after sedimentation. This deformation appears stronger in the western part being close to a major thrust, and thus it is possible that this deformation could be responsible for the high secondary porosity of Upper Cretaceous deposits. Microfacies analysis of these deposits showed in general that deep-sea depositional environments prevailed, nevertheless in a few cases indications for the presence of environments with a shallow character imply the existence of isolated carbonate platforms close to the studied sections. In the studied sections with an E-W direction, no lateral changes were observed in the depositional conditions within the same Formation introducing standard depositional conditions across the paleo basin.

Español.  Se dan a conocer nuevas localizaciones y datos corológicos para 98 especies (61 Rhodophyta, 22 Ochrophyta, 15 Chlorophyta) de algas bentónicas marinas recolectadas en el intermareal y submareal de más de 80 localidades de las costas atlánticas y cantábricas de la Península Ibérica. Polysiphonia devoniensis, P. fibrata y Zonaria tournefortii son novedad para Portugal y 5 especies (Bonnemaisonia hamifera, Calosiphonia vermicularis, P. devoniensis, Hincksia intermedia y Derbesia marina stadium Halicystis ovalis) son nuevas citas para Galicia. Paralelamente, se aportan 101 primeras citas provinciales (2 Guipúzcoa, 1 Vizcaya, 8 Cantabria, 5 Asturias, 7 Lugo, 1 A Coruña, 8 Pontevedra, 1 Beira litoral, 15 Estremadura, 20 Alentejo, 25 Algarve y 8 Cádiz) y, además, se dan a conocer 108 segundas citas provinciales. Aunque la flora bentónica marina del Atlántico Peninsular ha sido objeto de numerosos estudios, estos nuevos hallazgos corológicos ponen en evidencia que todavía son necesarios más estudios florísticos en estas costas.English.  In this work, we provide new records and geographical distribution data for 98 seaweeds (61 Rhodophyta, 22 Ochrophyta, 15 Chlorophyta) inhabiting more than 80 sites (intertidal and subtidal) of the Atlantic Iberian Peninsula. Polysiphonia devoniensis, P. fibrata y Zonaria tournefortii are new records for Portugal and 5 species (Bonnemaisonia hamifera, Calosiphonia vermicularis, P. devoniensis, Hincksia intermedia and Derbesia marina stadium Halicystis ovalis) are new records for Galicia. Moreover, 101 new records are reported for the first time in the studied provinces (2 Guipúzcoa, 1 Vizcaya, 8 Cantabria, 5 Asturias, 7 Lugo, 1 A Coruña, 8 Pontevedra, 1 Beira litoral, 15 Estremadura, 20 Alentejo, 25 Algarve y 8 Cádiz) and 108 for the second time. Although the Atlantic marine algae of the Iberian Peninsula are well studied, these new findings show that further floristic studies are necessary to complete our knowledge of the natural heritage of this region.
