TL;DR: There are more than 600 species of freshwater fungi with more known from temperate, as compared to tropical regions, and these are categorized into four groups depending on their form and life style: the ingoldian hyphomycetes; the aero-aquatic hyphcycete; the terrestrial-aquatics; and the submerged-aquatically-submerged hyphology.
Abstract: There are more than 600 species of freshwater fungi with more known from temperate, as compared to tropical regions. These includeca 340 ascomycetes, 300 deuteromycetes, and a number of lower fungi which are not discussed here.Aniptodera, Annulatascus, Massarina, Ophioceras andPseudohalonectria are common freshwater ascomycetes, which appear to be well adapted for this lifestyle either in their ascospore types or their competitive-degradative characters. The most common genera of wood-inhabiting deuteromycetes includeCancellidium, Dactylaria, Dictyosporium andHelicomyces. They are categorized into four groups depending on their form and life style: the ingoldian hyphomycetes; the aero-aquatic hyphomycetes; the terrestrial-aquatic hyphomycetes; and the submerged-aquatic hyphomycetes. The adaptations of aquatic fungi for their dispersal and subsequent attachment to new substrates are discussed.

TL;DR: Phylogenetic analysis of rDNA of trapping fungi in this study indicated that trapping organs may reflect evolutionary relationship, and appear more significant than conidiogenous cells and conidia for genus and species delimitation.
Abstract: Ribosomal DNA of 29 nematode-trapping fungi in the genera Arthrobotrys, Dactylella, Dudding- tonia, Geniculifera, Monacrosporium, Nematoctonus, and 5 nonpredacious, allied fungi in the genera Or- bilia, Trichothecium, Dactylaria, and Arthrobotrys was amplified by polymerase chain reaction and se- quenced using universal primers. Phylogenetic anal- ysis of 5.8S rDNA using parsimony indicated that 28 clampless nematode-trapping fungi were monophy- letic and have evolved from a common ancestor. Clamped Nematoctonus robustus, having a Hohenbue- helia basidiomycetous teleomorph, was phylogeneti- cally distant and the predacious habit was gained through convergent evolution. Nonpredacious Ar- throbotrys, Dactylaria, and Trichothecium species, de- spite having morphologically similar conidiogenous cells and conidia, actually were grouped in a geneti- cally distant region of the tree. Analysis of the more variable internal transcribed spacer, ITS1 and ITS2, revealed that the 28 nematode-trapping fungi were separated into 4 clades, each with a unique trapping device. Phylogenetic analysis of rDNA of trapping fungi in this study indicated that trapping organs may reflect evolutionary relationship, and appear more significant than conidiogenous cells and conidia for genus and species delimitation. We suggest that the circumscription of the Arthrobotrys-Dactylella-Mona- crosporium complex be revised to provide a natural

TL;DR: The combination of morphological and molecular characters, such as spore morphology and ITS ribosomal DNA sequences data, suggested that conidial shape could be a primary character to distinguish Pyricularia from related genera.
Abstract: The phylogenetic relationships of Pyricularia species and species from related genera were established from sequences of the internal transcribed spacer ribosomal RNA gene. Phylogenetic analysis disclosed a consistent correlation with spore morphology. Most Pyricularia species studied, and two species of Dactylaria that have obpyriform conidia, fell within the Magnaporthaceae cluster with high bootstrap support. Pyricularia variabilis was more related to Dactylaria, Tumularia or Ochroconis species than to the Magnaporthaceae. Dactylaria and species of Nakataea, Ochroconis, Pyriculariopsis and Tumularia were distinct from the Magnaporthaceae, and the genus Dactylaria is polyphyletic. The combination of morphological and molecular characters, such as spore morphology and ITS ribosomal DNA sequences data, suggested that conidial shape could be a primary character to distinguish Pyricularia from related genera.
