Larvae of Aedes aegypti, Ae. vexans and Culiseta inornata were used to study the pathogenicity of the hyphomycete fungus Tolypocladium cylindrosporum. Experiments consisted of continuous exposure of second-instar larvae to 5 concentrations of conidia at 10, 15, 20 and 25 degrees C. The 3 test species were susceptible at all temperatures tested. There was generally a direct relationship between ...

Aquatic hyphomycetes strongly contribute to organic matter dynamics in streams, but their abilities to colonize leaf litter buried in streambed sediments remain unexplored. Here, we conducted field and laboratory experiments (slow-filtration columns and stream-simulating microcosms) to test the following hypotheses: (i) that the hyporheic habitat acting as a physical sieve for spores filters ou...

This supplement to the taxonomic monograph The Genera of Hyphomycetes summarises information on 23 accepted new genera and c. 160 species described in 2011. These include three dematiaceous genera (Funbolia, Noosia, Pyrigemmula, all related to Dothideomycetes), a bulbil-producing genus, Spiroplana (Pleosporales), and two endophytic genera, the sterile Periglandula (Clavicipitaceae), and the hya...

Cercosporoid fungi (former Cercospora s. lat.) represent one of the largest groups of hyphomycetes belonging to the Mycosphaerellaceae (Ascomycota). They include asexual morphs, asexual holomorphs or species with mycosphaerella-like sexual morphs. Most of them are leaf-spotting plant pathogens with special phytopathological relevance. The only monograph of Cercospora s. lat., published by Chupp...

Nine species of saprophytic hyphomycetes (anamorphic fungi), collected on plant debris from two different localities of southeast Florida, are recorded for the first time from the United States. They are: Anungitea fragilis, Beltraniella havanensis, Canalisporium caribense, Circinotrichum papakurae, Dictyosporium micronesicum, D. subramanianii, Dischloridium laeense, Gyrothrix verticillata and ...

The phylogenetic placement of the monotypic dematiaceous hyphomycete genus Xanthoriicola was investigated. Sequences of the nLSU region were obtained from 11 specimens of X. physciae, which formed a single clade supported both by parsimony (91 %), and maximum likelihood (100 %) bootstraps, and Bayesian Posterior Probabilities (1.0). The closest relatives in the parsimony analysis were species o...

The Eocene (~ 48.7 Ma, Ypresian-Lutetian) Princeton Chert of British Columbia, Canada, has long been recognized as a significant paleobotanical locality, and a diverse assemblage of anatomically preserved fossil plants has been extensively documented. Co-occurring fossil fungi also have been observed, but the full scope of their diversity has yet to be comprehensively assessed. Here, we present...
