Various best-choice problems related to the planar homogeneous Poisson process in finite or semi-infinite rectangle are studied. The analysis is largely based on properties of the onedimensional box-area process associated with the sequence of records. We prove a series of distributional identities involving exponential and uniform random variables, and resolve the Petruccelli-Porosinski-Samuel...

Based on morphology, fungal species have been considered widespread and as a result names of species from Europe or eastern North America were applied to species in western North America. However, DNA sequences have shown that many western taxa are different from their European counterparts; one such case is presented here. Comparisons of ITS and LSU rDNA sequences from ectomycorrhizal root tip...

Three Hypomyces and one Cladobotryum species are studied and reported as new records and also new anamorph/teleomorph connections of fungicolous fungi for Iran. Anamorphs of two species H. aurantius and H. rosellus (Cladobotryum varium and C. dendroides, respectively) have already been reported from Iran. The anamorph/teleomorph association of H. polyporinus/C. clavisporum was also found and wa...

During 2003-05 Iranian provinces in the Southern Caspian coast (Gilan, Mazandaran and GolestanProvinces, N. Iran) were investigated in order to collect and identify fungicolous species on various fungal hosts. Fifty-seven isolates were obtained and these were classified into seven genera, Acremonium, Cladobotryum, Fusarium, Sepedonium, Hypomyces, Lecanicillium, Simplicillium and Trichoderma. Am...
