The worldwide-distributed aquatic fungus Articulospora tetracladia Ingold is a dominant sporulating species in streams of the Northwest Iberian Peninsula. To elucidate the genetic diversity of A. tetracladia, we analyzed isolates collected from various types of plant litter or foam in streams from North and Central Portugal and North Spain, between 2000 and 2010. Genetic diversity of these fungal populations was assessed by denaturing gradient gel electrophoresis (DGGE) fingerprints and by using ITS1-5.8S-ITS2 barcodes. Moreover, ITS1-5.8S-ITS2 barcodes of A. tetracladia reported in other parts of the world (Central Europe, United Kingdom, Canada, Japan and Malaysia) were retrieved from the National Center for Biotechnology (NCBI) and the National Institute of Technology and Evaluation Biological Resource Center (NBRC) to probe into genetic diversity of A. tetracladia. PCR-DGGE of ITS2 region of 50 Iberian fungal isolates distinguished eight operational taxonomic units (OTUs), which were similar to those obtained from neighboring trees based on ITS2 gene sequences. On the other hand, ITS1-5.8S-ITS2 barcodes of 68 fungal isolates yielded nine OTUs, but five fungal isolates were not assigned to any of these OTUs. Molecular diversity was highest for OTU-8, which included only European isolates. Two haplotypes were observed within OTU-8 and OTU-9, while only one haplotype was found within each of the remaining OTUs. Malaysia did not share haplotypes with other countries. Overall results indicate that, apart from the Malaysian genotypes, A. tetracladia genotypes were geographically widespread irrespective of sampling time, sites or substrates. Furthermore, PCR-DGGE appeared to be a rapid tool for assessing intraspecific diversity of aquatic hyphomycetes.

“…A few species, found only on the plain, are considered tropical (L. curvula Ingold and C. chaetocladia Ranzoni); most, whether from the plain or from mountain streams, are typically of temperate climates; a few are isolated only in mountain streams. Quantitative data, obtained by means of membrane filtration (8 μm pore size), are reported in some other papers (Del Frate &Caretta 1983 Del Frate, G andCaretta, G. 1983. Aquatic hyphomycetes of a mountain stream in Valsesia (Piemonte).…”

“…The first Italian records were published by Ciferri (1959Ciferri, R. 1959 who isolated 11 species from the Po and Ticino basins and irrigation canals in Pavia and its environs. No further data were published in Italy until 1983, when a study on aquatic hyphomycetes from some streams located on the plain (Ticino Park) and in mountains of northern Italy was reported (Del Frate 1983 Del Frate, G andCaretta, G. 1983.

The fungal biodiversity in its overall is mostly still unknown and the ecological role of these organisms, particularly in some border ecosystems, is often underestimated. This study aims to give both an overview of the state of the art and to present new data on the mycodiversity in some peculiar environments as rocks, beach sand, and water in Italy. Particularly, rock fungi are here reported from high mountain peaks, sea cliffs, and monuments; sand associated fungi from beach ecosystems in Puglia and Ligurian coasts; marine fungi associated with the endemic seagrass of the Mediterranean Posidonia oceanica L.; aquatic hyphomycetes (Ingoldian fungi) from both streams in the Ticino Natural Park and lentic water in Lago Maggiore; fungi from the water distribution system in Turin. Ecological and evolutive considerations are put forward.

Summary:The seasonal variat'ion in the occurrence of water-borne hyphomycetes in the two &reams, viz. Kempu Hole and Kumaradhara, was investigated during 1983 and 1984. The fungi were isolated by using the four methods, viz. leaf litter analysis, water filtration and analysis of natural and induced foam. Thirty-six species of hyphomycetes in Kempu Hole and twenty species in Kumaradhara were recorded. Lunulospora curvula and Triscelophorus naonosporus were observed in high frequency in all seasons in both the streams. The organisms like Dactylella aquatica, Camposporium pellucidurn, Clavatospara, filiformis, Dactylella oviparasitica, Plabellospora crassa, Tetraciadiurn marchalianum, Tetroploa sp., Tetraploa aristata, Alatospora acuminata, Condylospora spumigena, Helicosporium sp. 1, Helicospovium sp. 2 , Diplocladiella sealaroides, Phnlnngispora co?~:;tricta and Isthrnotricladia laeensis were found to occur wit8h a very low frequency. I n both the &reams a maximum number of organisms were colloctcd following the periods of heavy rains. The temperature and pH of stream water do not seem to affect the occurrence of hyphomycetes in st,reams of this region. On the other hand, the availability of subst,rates and the oxygen concentration of stream water seem to influence the occurrence of these fungi.

Aquatic Hyphomycetes of a mountain stream in Valsesia (Piemonte)

Abstract: The conidia of aquatic Hyphomycetes in a mountain stream in Italy were studied. Thirteen species previously unknown from Italy were recorded. The concentration of conidia in the waters of the stream reached a maximum from October to December, and a minimum in August.
