We conducted a species diversity study of the hypogeous Ascomycetes of Israel. The hypogeous Ascomycetes in Israel include members of the families Pyronemataceae, Pezizaceae, and Tuberaceae, which are represented by seven species: Hydnocystis piligera, Terfezia arenaria, T. claveryi, T. oligosperma, Tirmania africana, Tuber asa, and T. nitidum; only T. asa is new to Israeli mycobiota. Synonymy,...

Most marine pyrenomycetes are lignicolous, but some are epiphytic on marine phanerogims and algae. Meyers (1957) listed 30 species of algae known to be attacked by these fungi. A number of reports dealing with marine ascomycetes on algal hosts appeared before 1900, the most noteworthy being those of Winter (1887), and Jones (1898). Cotton (1908) described a pyrenomycete on Ascophyllum nodosum (...

To determine whether host species influence the composition of fungal communities, the ascomycetes and basidiomycetes present on three tree species (Prioria copaifera (Fabaceae), Quararibea asterolepis (Bombacaceae), and Trichilia tuberculata (Meliaceae)) were sampled on the 50-ha Forest Dynamics Project plot in lowland moist tropical forest on Barro Colorado Island, Panama. The most abundant f...

three species of the genus xylaria (xylariaceae) are presented based on collections from guilan province, iran. both morphological and molecular characteristics were used in order to identify these species. xylaria longissima sp. nov. is described and illustrated as a new xylaria species and x. cf. striata and x. xylarioides are reported as new records from iranian mycobiota. xylaria longissima...

this study is a review on the genus helvella (pezizales, helvellaceae) in iran. study on samples deposited in iran fungal herbarium along with the fresh materials collected by the author revealed that seven species of helvella, h. acetabulum, h. atra, h. crispa, h. elastica, h. ephippium, h. lacunosa and h. leucopus (as h. monachella) have already been reported from iran. three other species vi...

The two biotechnologically important Ascomycetes, Pichia membranifaciens and Debaryomyces hansenii, were tested (in active and inactive form), in the present study for efficient bioreduction of trivalent aurum to gold nanoparticles. Strong surface plasmon resonance was observed, between 530 and 540 nm, from the gold nanoparticles recovered from the test Ascomycetes. The characterization of the ...

Yeast-like endosymbionts (YLSs) of insects often are restricted to specific hosts and are essential to the host's survival. For example, in planthoppers (Homoptera: Delphacidae), endosymbionts function in sterol utilization and nitrogen recycling for the hosts. Our study, designed to investigate evolutionary changes in the YLS lineage involved in the planthopper association, strongly suggests a...
