Abstract
Collections from freshwater habitats of undescribed pyrenomycetes with scolecosporous ascospores were characterized using morphological characters, restriction analysis of PCR amplified rDNAs, and 18S rDNA sequences. Five species of Ophioceras were resolved and one species was excluded from the genus. Based on phylogenetic analysis of partial 18S rDNA sequences, species of Pseudohalonectria form a sister clade to Ophioceras thereby supporting the integrity but close relationship of these two freshwater genera. Gaeumannomyces graminis falls within the Ophioceras/Pseudohalonectria clade and is a sister taxon to a species of Ophioceras. This calls to question the reliability of the morphological and biological characters currently used to separate Gaeumannomyces from Ophioceras. In parsimony analyses, Ophioceras and Pseudohalonectria are more closely related to two species in the Ophiostomatales than to species in the Sordariales or Diaporthales. However, such a relationship is not evident in analyses.
