Preliminary Study of Aquatic Hyphomycetes from Venezuelan streams

Fifty species of aquatic hyphomycetes from seven streams, six of which are located in Venezuelan National Parks are reported. Community similarity of hyphomycetes was low since only four species were common to all sites: Campylospora chaetocladia Ranzoni, Clavatospora tentacula Sv.Nilsson, Triscelop...

Description
Summary:Fifty species of aquatic hyphomycetes from seven streams, six of which are located in Venezuelan National Parks are reported. Community similarity of hyphomycetes was low since only four species were common to all sites: Campylospora chaetocladia Ranzoni, Clavatospora tentacula Sv.Nilsson, Triscelophorus acuminatus Nawawi and Triscelophorus monosporus Ingold. The streams had unique species whose number varies between one and three. In Río Los Castillos the species were: Anguillospora longissima (Sacc. & P.Syd.) Ingold, Angulospora aquatica Sv.Nilsson and Phalangispora nawawi Kuthub.; for Quebrada Guatopo the species were Clavariopsis azlanii Nawawi, Condylospora flexuosa Nawawi & Kuthub. and Hydrometrospora symmetrica J.Gönczöl & Révay; for Río Cabriales the species were Camposporium antennatum Harkn., Phalangispora constrica Nawawi & J.Webster, Scorpiosporium chaetocladium (Ingold) Dyko. Quebrada Martinera and Río To-come had one species unique Isthmotricladia gombakiensis Nawawi and Flabellospora verticillataAlas., respectively. Río Cúpira and Quebrada Ingenio do not have species exclusively to any of them. Thirty species are reported for the first time for the country.
