Abstract Three hepatic failure poisoning incidents caused by Lepiota brunneoincarnata and Lepiota venenata mushrooms have been occurred in China in 2017, L. venenata has been described as a new species. However, the cyclopeptide toxins of these lethal mushrooms remain poorly understood. In this study, the composition and content of amatoxins in L. brunneoincarnata and L. venenata are analyzed and compared

Identification, Characterization, and Pathogenicity of Colletotrichum Species Causing Anthracnose of Peach in Korea Mycobiology (IF 1.416) Pub Date : 2020-05-19 Dae Min Lee; Oliul Hassan; Taehyun Chang
Abstract Peach (Prunus persica L.) is one of the major fruit crops in South Korea, along with apple, persimmon, and Asian pears. Peach anthracnose is a continuing threat to growers and is accountable for enormous economic loss. In July 2018, anthracnose of peach appeared at different peach orchards in Gyeongsangbuk-do region, Korea. The typical anthracnose symptoms (brown, circular, and necrotic lesions)

First Report of Green Mold Disease Caused by Trichoderma hengshanicum on Ganoderma lingzhi Mycobiology (IF 1.416) Pub Date : 2020-07-24 Mingzhu Cai; Muhmmad Idrees; Yi Zhou; Chunlan Zhang; Jize Xu
Abstract Ganoderma lingzhi is a well-known source of natural fungal medicines which has been given for the treatment of several diseases. China is one of the major commercial producers of Ganoderma mushroom worldwide. However, with the expansion of the commercial cultivation, the occurrence of the fungal diseases on G. lingzhi has also been increased. The green mold disease symptoms were observed in

First Report of Gray Mold Disease on Endangered Species Cypripedium japonicum Mycobiology (IF 1.416) Pub Date : 2020-07-20 Chang-Wook Jeon; Da-Ran Kim; Geun Hye Gang; Byung-Bu Kim; Nam Ho Kim; Seong-Yeol Nam; Youn-Sig Kwak
Abstract Cypripedium japonicum is known to be the indigenous plant to Korea, Japan, and China. However, C. japonicum represents the most critically endangered plant species in South Korea. The plant is esthetically pleasing due to its flower, which is larger than any other orchidaceous species. Disease symptoms relating to gray mold were observed on C. japonicum in May 2019. The suspected pathogen

Occurrence of Cercospora Leaf Spot Caused by Cercospora cf. flagellaris on Melon in Korea Mycobiology (IF 1.416) Pub Date : 2020-07-20 Mi-Jeong Park; Chang-Gi Back; Jong-Han Park
Abstract In 2016, a cercosporoid fungus was found from leaf spot symptoms on melon in Korea. The fungus isolated from the plant was identified based on morphological characteristics and sequence analyses of five genes (ITS rDNA, translation elongation factor 1-α, actin, calmodulin, and histone H3). The fungal isolate was found to be pathogenic to melon. The results confirm that the fungus associated

Experimental Analysis of Interactions Among Saprotrophic Fungi from A Phosphorous-Poor Desert Oasis in the Chihuahuan Desert Mycobiology (IF 1.416) Pub Date : 2020-07-13 Constanza Marini-Macouzet; Luis Muñoz; Aldo Gonzalez-Rubio; Luis E. Eguiarte; Valeria Souza; Patricia Velez
Abstract Fungal ecological interactions play a key role in structuring community assemblages. These associations may involve both antagonistic and synergistic relationships, which are commonly influenced by abiotic factors such as nutrient conditions. However, information for extreme, oligotrophic systems remain poor. Herein, interactions among key members of the aquatic transient fungal community

Note of Five Unrecorded Mushrooms Including Three Rare Species on Mount Juwang in Korea Mycobiology (IF 1.416) Pub Date : 2020-05-13 Sun Lul Kwon; Seokyoon Jang; Changmu Kim; Young Woon Lim; Jae-Jin Kim
Abstract The Mount Juwang was designated as a national park in 1976 because of its unique bedrock geology. Although Juwang National Park has maintained its natural ecosystem well, few macrofungal surveys have been carried out. As a part of a project supported by the National Institute of Biological Resources (NIBR) for the discovery of indigenous fungal species, we surveyed the mushrooms in Juwang

Draft Genome Sequence of Alternaria alternata JS-1623, a Fungal Endophyte of Abies koreana Mycobiology (IF 1.416) Pub Date : 2020-05-07 Sook-Young Park; Jongbum Jeon; Jung A. Kim; Mi Jin Jeon; Min-Hye Jeong; Youngmin Kim; Yerim Lee; Hyunjung Chung; Yong-Hwan Lee; Soonok Kim
Abstract Alternaria alternata JS-1623 is an endophytic fungus isolated from a stem tissue of Korean fir, Abies koreana. Ethyl acetate extracts of culture filtrates exhibited anti-inflammatory activity in LPS induced microglia BV-2 cell without cytotoxicity. Here we report a 33.67 Mb sized genome assembly of JS-1623 comprised of 13 scaffolds with N50 of 4.96 Mb, and 92.41% of BUSCO completeness. GC

Abstract Androgen-independent prostate cancer accounts for mortality in the world. In this study, various extracts of a medical fungus dubbed Ganoderma formosanum were screened for inhibition of DU145 cells, an androgen-independent prostate cancer cell line. Results demonstrated that both hexane (GF-EH) and butanol (GF-EB) fraction of G. formosanum ethanol extract inhibited DU145 cell viability in

Morphology and Molecular Characterization of a Fungus from the Alternaria alternata Species Complex Causing Black Spots on Pyrus sinkiangensis (Koerle pear) Mycobiology (IF 1.416) Pub Date : 2020-04-14 Sein Lai Lai Aung; Hai Feng Liu; Dong Fang Pei; Bing Bin Lu; May Moe Oo; Jian Xin Deng
Abstract A small-spored Alternaria was found from black spots of storaged Koerle pear (Pyrus sinkiangensis), one of the economically important fruit in Xinjiang province, China. The morphology is similar to A. limoniasperae but obviously different in secondary conidiophores and conidial septa. A phylogenetic analysis using sequence datasets of ITS, GAPDH, TEF1, RPB2, Alt a1, OPA10–2, and EndoPG genes
