A new type of diffraction range finder is disclosed that places the primary grating at an angle of grazing incidence relative to the receiver. The new design offers improvements over earlier prototypes in reduced package size, reduced chirp depth and a highly anamorphic behavior that provides a high profile to depth ratio. Demonstrations with transmission and reflection types of diffraction gra...

The anamorphic pycnidial fungus Ascochyta pisi is one member of a species complex that causes Ascochyta blight of pea, a potentially devastating disease. The teleomorphic state of this fungus was induced under laboratory conditions. Using morphological and molecular characters, we placed the teleomorph within the genus Didymella as D. pisi and describe a heterothallic mating system using a PCR-...

During 2009–10, the presence of ascomycetous species in soil was studied in Fars province. Isolates were recovered from soil using modified Czapek (Raper et al. 1973), malt extract agar (MEA) and potato dextrose agar (PDA). Teleomorphic characteristics such as morphology of ascocarps, asci, ascospores and anamorphic characteristics such as conidiophores, phialides, conidia and chlamydospores we...

in this paper the taxonomy of some previously reported taxa as cercospora apii s.lat. in iran, is discussed and some new records are listed. cercospora species on abelia grandiflora (c. deutziae), erythrina crista-galli (c. erythrinicola), euphorbia heterophylla (c. pulcherrimae) and zanthedeschia aethiopica (c. richardiicola) are new for mycobiota of iran. cercospora iridis which was previousl...

Phylogenetic relationships among heterobasidiomycetous yeasts, including anamorphic and teleomorphic taxa, have been compared from the sequence similarity of small (18S) and large (25S) subunit ribosomal RNA. Species examined were Cystofilobasidium capitatum, Filobasidiella neoformans, Fi/obasidium floriforme, Leucosporidium scottii, Malassezia furfur, M. pachydermatis, Phaffia rhodozyma, Rhodo...

Changing climate is expected to alter precipitation patterns in the Arctic, with consequences for subsurface temperature and moisture conditions, community structure, and nutrient mobilization through microbial belowground processes. Here, we address the effect of increased snow depth on the variation in species richness and community structure of ectomycorrhizal (ECM) and saprotrophic fungi. S...
