Species of Leucadendron, Leucospermum and Protea (Proteaceae) are in high demand for the international floriculture market due to their brightly coloured and textured flowers or bracts. Fungal pathogens, however, create a serious problem in cultivating flawless blooms. The aim of the present study was to characterise several of these pathogens using morphology, culture characteristics, and DNA ...

Ecological stoichiometry generally assumes that heterotrophs have a higher degree of elemental homeostasis than autotrophs. Differences between fixed consumer nutrient requirements and nutrients available in resources allow prediction of the intensity of nutrient recycling ensured by heterotrophs. Despite their fundamental role in detritus decomposition, extremely fewdata are currently availabl...

With a profound knowledge of how physico-chemical parameters affect these communities, microbial communities could be used as indicators for environmental changes and for risk assessment studies. We studied aquatic hyphomycete communities in ponds from sites shaped by intense human activities (namely the “Mansfeld region”) and Urmil river, there are no sources of man made effluents in Chhatarpu...

The paper reports two new records of a rare fungicolous fungus Pseudotrichia mutabilis (Melanommataceae, Pleosporales) from Ukraine. Both specimens were collected within protected areas in association with xylariaceous species, Hypoxylon crocopeplum and Rosellinia corticium. provides descriptions, nomenclatural data, original illustrations the reported species. Information on substrate speciali...

Gypsy moth, Lymantria dispar, populations were sampled in four eastern North American states during 1991 and 1992 to evaluate levels of hyphomycete infection in association with releases of the Asian gypsy moth pathogen Entomophaga maimaiga. Paecilomyces farinosus was the most abundant hyphomycete species, occurring at the majority of sites, although levels of infection averaged only 4.6% (1991...

The genus Hypomyces contains fungi that grow on mushrooms, including agarics, boletes, and Aphyllophorales. While 53 Hypomyces species have been reported worldwide, only one was in Korea. In this study, two new Korean species were identified as H. luteovirens and H. tubariicola based on morphology and internal transcribed spacer sequencing.

Attachment of conidia on leaves is a critical first step in the life cycle of aquatic hyphomycetes in streams. In a first series of microcosm experiments, attachment success of three common aquatic hyphomycete species differing in conidial shape (compact, filiform and tetraradiate) was determined on two leaf species, black alder and downy oak. Fungal species identity and leaf surface structure ...

ABSTRACT Leaf samples of forage bermudagrass with symptoms of infection by species of Bipolaris, Curvularia, and Exserohilum (dematiaceous hyphomycetes) were collected from three swine waste application sites in Mississippi at eight sampling times during each of 3 years. Samples were assayed for pathogens by observing sporulation on plated leaf tissue. Among 3,600 leaves assayed, eight species ...

The killer effect of 36 Hansenula, Pichia, Saccharomyces, and Candida species on 26 hyphomycetes isolates, 1 isolate of the achlorophyllous microorganism Prototheca, 4 isolates of the lipophilic yeast Malassezia, 1 isolate of the aerobic actinomycete Nocardia, and 19 isolates of bacteria was studied. The killer phenomenon, which was previously considered to be restricted to yeasts, was found to...
