The inhibitory effects of fungi (Acremonium, Alternaria, Cladosporium, Cylindrocarpon, Fusarium, Gliocladium, Gymnoascus, Penicillium, Pestalotiopsis, Phoma, Phytophthora, Pythium, Rhizoctonia, Sordaria, Trichoderma and Verticillium spp.) isolated from the rhizosphere of 2-year-old plants of S. pseudocamellia on the growth of F. oxysporum and R. solani were studied using the biotic series method. The rhizosphere fungi did not inhibit the growth of both pathogens..

The molecular mechanisms by which terrestrial fungi grow into the air in order to reproduce and for spore dispersal are discussed. Fungal hydrophobins and proteinaceous repellents are included. It is concluded that filamentous fungi have >1 type ofmorphogenetic protein that is capable of responding to external environmental conditions and generating surface hydrophobicity. It is suggested that environmental factors may induce the activity of specific morphogenetic proteins.

Recent suggestions that oomycetes should not be considered to be fungi are critically evaluated. It is suggested that although oomycetes are phylogenetically distant from other fungi, it is impractical to restrict the use of the term fungus to microorganisms that are members of the Phylum Fungi. Characteristics of fungi which oomycetes confirm to are listed as: (1) absorptive mode of nutrition; (2) growth by polarized hyphal extension; and (3) reproduction involving spore formation. It is suggestedthat 2 distinct meanings of the word fungus should be maintained. These are (a) the strict taxonomic epithet covering members of the Kingdom Fungi; and (b) a practical reference to microorganisms studied my mycologists and sharing the characteristics offungi listed above.

The distribution of phytotrophic fungi in 3 main types of plant communities in the Nature Reserve Medobory (Ternopil region, Ukraine) is described. It was established that 206 species of herbophyllous and 93 species of xylotrophic fungi were distributed in different phytocoenoses of the Reserve. Oomycetes included 29, Ascomycetes 106, Basidiomycetes 129, Hyphomycetes 9 and Coelomycetes 28 species. Rust fungi were collected from 145 host plant species, powdery mildews from 114 species and Peronosporales from 33 species. A combination of species from different taxonomical groups on the same plant organ was detected.

A total of 126 fungal species from 40 genera and 4 classes was found in soils of the Kolyma region, Russia, showing features typical for the northern soil mycobiota, i.e. the predominance of penicilia, rare occurrence of Aspergillus and ascomycete species and a high quantity of different forms of sterile mycelium. The tundra component in the studied mycobiota was low in species number, although, one representative of tundra micromycetes, Geomyces pannorum, quantitatively predominated among oligotrophic and cellulolytic fungi. Similarly, typical micromycete complexes from the soils of the studied communities reflect similarity of these soils in leaf litter composition, acidity and hydrothermal conditions.

摘要 :
Historically, the abbreviation 'Tul.' was used indiscriminately to indicate authorship by L.-R. Tulasne as sole author and by L.-R. & C. Tulasne as joint authors. This ambiguity continues to result in misattribution of many names for which the author has previously been designated as 'Tul.', for example the genus Hypomyces. Linguistic analysis of numerous papers published by the Tulasne brothers confirms that they were joint authors of the protologue of the genus Hypomyces and its original 18 species. Therefore, using modern standard botanical author abbreviations, these names should be attributed to 'Tul. & C. Tul.', and not to 'Tul.'....

Nine fungal species, namely, Alternaria alternata, Aspergillus flavus, Aspergillus niger, Curvularia lunata [Cochliobolus lunatus], Fusarium moniliforme [Gibberella moniliformis], Helminthosporium sativum [Cochliobolus sativum], Mucor sp., Penicillium notatum and Rhizopus nigricans [R. stolonifer], were observed on seven seed samples of chickpea. All fungi developed on agar and blotter paper, except for P. notatum which developed on agar plate only. Genotype Plant G 186 was found to harbour the maximum number of fungal species (all the nine species), followed by Udai, Radhey, Pragati, Pusa 286, K-850 and Awarodhi. Alternaria alternata, Mucor sp. and R. nigricans were observed on the seeds of all the genotypes. Aspergillus flavus was the next dominant fungal species observed on six genotypes. Aspergillus niger and F. moniliforme were observed on five, H. sativum on four, C. lunata on three and P. notatum on two genotypes.

Five known and 3 new dihydroisocoumarins were isolated from different fungi. The new isocoumarins were 5-chloro-6-hydroxymellein, 5-chloro-4,6-dihydroxymellein and 5,6-dihydroxymellein. The absolute configuration of these secondary metabolites was confirmed by CD measurements and in 2 cases by X-ray structure analysis.
