Sclerotinia sclerotiorum is a typical necrotrophic plant pathogenic fungus that distributes worldwide and causes severe diseases on a broad-range of plant species. Studies on S. sclerotiorum have been mainly focused on biology and pathology. The development of high-throughput technologies enabled multi-omics approaches for systems biology. This review summarizes current researches on S. sclerotiorum and proposes systemic strategies for understanding its biology and pathology, to provide novel insights and references for further investigation on molecular biology and pathogenesis of the pathogenic fungi and the pathosystems.

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, locations, collection data, general distribution, distribution in Israel, descriptions, a key to identification, illustrations, and taxonomic remarks are provided.

Cladonia peziziformis (With.) J.R. Laundon was collected from Baega mountain, Jeonnam Province, Korea in 2008. It is characterized by short and slender podetia with verruculose surface, split along the sides. Apothecia large, pale brown, always growing on the top of the podetia. Primary squamules shell-like, thick, and convex. Fumarprotocetraric acid contained in thallus. This is the first record of this species in Korea.

Field studies were conducted over two seasons during the summers of 1997 and 1998 to investigate the effects of different spatial arrangements(random or highly aggregated) of sclerotia of Sclerotinia sclerotiorum and alginate pellet types(bran or polyethylene glycol) on colonization of sclerotia by Trichoderma spp. Treatment with alginate pellets increased the mean percentages of sclerotia colonized by Trichoderma spp. in both years. Distribution patterns of sclerotia affected the mean percentage of sclerotia colonized by Trichoderma spp. in both years, indicating that a highly aggregated distribution of sclerotia was more favorable to colonization by Trichoderma spp. The effects of the different pellet types(bran or PEG) were not siginificant in both years(P>0.05). The application of higher densities(200 pellets per 1 m2) of alginate pellets resulted in higher mean percentages of sclerotia colonized by Trichoderma spp. in 1998(p<0.05), but did not in 1997.

The lichenicolous fungi flora of South Korea is poorly known. During recent field trips to various parts of South Korea and after an extensive examination of herbarium lichen specimens, we encountered a lichenicolous fungi growing over a thallus of the lichen Ochrolechia yasudae Vain., characterized by small black apothecia with mostly three-septate brown ascospores. It was identified as Dactylospora glaucomarioides. This is the first report of this lichenicolous fungus from South Korea. A taxonomic description and comments are presented.

We performed a taxonomic study on two species of the genus Bryoria from the Sino-Himalayas, SW-China. B. nadvornikiana is new to China and B. furcellata is new to Yunnan and Sichuan provinces in the Sino-Himalayas. Morphology, habitat, distributions and chemistry of the two species are discussed.

Biochemical variability among 20 Indian isolates of Sclerotinia sclerotiorum collected from different hosts/soil samples from different localities in India is reported. High Performance Liquid Chromatographic (HPLC) analysis of ethyl acetate fraction of culture filtrate, mycelia, sclerotia and sclerotial exudate showed 15~23 peaks but only 11 could be identified. They were tannic, gallic, oxalic, caffeic, vanillic, ferulic, O-coumeric, chlorogenic, cinnamic, salicylic and gentisic acids. The amount of phenolic compounds varied among the culture filtrates, mycelia, sclerotia and sclerotial exudates of S. sclerotiorum.

Thirty-seven single spore isolates were obtained from specimens of ascomycetous fruiting bodies collected from Mt. Suri, Anyang in Korea. The fungal specimens and isolates were identified as Dumontinia tuberosa based on their morphological and cultural characteristics. This is the first record of this fungus occurring in Korea.

Lichen genus Sarcographa Fee, a stromatoid Graphidacean taxa, was newly found in Geomun Island, Jeonnam province. The lichen grew on the bark of Camellia japonica and Eurya emarginata along the coastal line of the island. It was identified as Sarcographa tricosa (Ach.) Mull. Arg. for the first time in Korea.

The capability of higher ascomyceteous fungi to cause typical soft-rot decay for wood under laboratory conditions is reviewed and discussed. Fungi tested were extremely active in the decomposition of timbers. Scanning electron micrographs illustrated typical soft-rot decay pattern of higher wood decay ascomycetes, with the exception of H. trugodes that caused white-rot decay. Most of the fungi tested could be grouped as soft-rot fungi that showed typical soft-rot type II. Hypha confined primarily to the resin canals in softwoods or vessel elements in hardwoods and spread tracheid to tracheid via pits of cell wall to cell wall with mechanical force.
