“…The pathology has been detected and reported in most edible mushroomgrowing countries, including: Australia (Fletcher et al, 2004), Belgium (Desrumeaux, 2005), China (Zuo et al, 2016), Canada (Howard et al, 1994), France (Largeteau & Savoie, 2010), Korea (Back et al, 2010), India (Bhatt & Singh, 2002), Ireland (McKay et al, 1999, Japan (Sawada et al, 2005), New Zealand (De Hoog, 1978), Poland (Ślusarski et al, 2012), Serbia (Potočnik et al, 2008), South Africa (Eicker, 1984), Spain (Gea et al, 2012), Taiwan (Kirschner et al, 2007), Turkey (Bora & Özaktan, 2000); UK (Adie et al, 2006) and the USA (Beyer & Kremser, 2004).…”

“…must be evaluated by two independent methods: (1) morphology: screening for aurofusarin and camphor odour producers, registering conidia and phialide size as well as taxonomic characters (Carrasco et al, 2016a); and (2) molecular and phylogenetic analysis. The best approach for complete molecular identification involves implementation of multigene phylogenetic analyses, including sequencing of the internal transcribed spacer (ITS) region of ribosomal DNA (rDNA), RNA polymerase subunit I (RPB1), DNA-dependent RNA polymerase subunit II (RPB2) and translation elongation factor (TEF) genes (Tamm & Põldmaa, 2013;Zuo et al, 2016). When plated on potato dextrose agar (PDA) these fungi develop a greyish-white mycelium with the reverse side of the plate turning yellow in few days.…”

“…Arnold, is currently the most cited causal agent of cobweb. It has recently been described as parasitizing different edible crops in Africa, Asia and Europe, including Agaricus bisporus, Pleurotus eryngii and Ganoderma lucidum (Back et al, 2010;Chakwiya et al, 2015;Carrasco et al, 2016a;Zuo et al, 2016;Gea et al, 2017). C. mycophilum is also a red pigment producer in vitro (Carrasco et al, 2016a).…”

“…As soon as a primary cobweb outbreak is located over the casing or carpophores, it must be treated before sporulation, covering the infected area with thick damp paper to avoid the release of conidia and disease dispersion (Pyck & Grogan, 2015). (Back et al, 2012;Kim et al, 2014;Chakwiya et al, 2015;Carrasco et al, 2016a;Zuo et al, 2016). However, several other species have been reported as causing this pathology in commercial mushroom crops.…”

Cobweb is a fungal disease of commercially cultivated mushrooms. Several members of the ascomycete genus Cladobotryum sp. have been reported as causal agents. White button mushroom is the most frequently cited host, but a wide range of cultivated edible mushrooms suffer cobweb. The pathology causes production losses and reduces the crop surface available. The parasite produces a great number of harmful conidia that can be released easily and distributed throughout the mushroom farm to generate secondary points of infection. To prevent initial outbreaks, hygiene is of primary importance within the facilities dedicated to mushroom cultivation, while additional measures must be implemented to control and reduce cobweb if there is an outbreak, including chemical and biological methods. This review summarizes and discusses the knowledge available on the historic occurrence of cobweb and its impact on commercial mushroom crops worldwide. Causal agents, disease ecology, including the primary source of infection and the dispersal of harmful conidia are also reviewed. Finally, control treatments to prevent the disease from breaking out are discussed.

Diversity of Cladobotryum mycophilum isolates associated with cobweb disease of Agaricus bisporus in the south African mushroom industry

et al. 2019

View full text Add to dashboard Cite

Cladobotryum species and strain diversity of isolates collected from cobweb symptomatic Agaricus bisporus or infected casing soil were investigated due to increased incidences of the disease in the South African mushroom industry. Samples were collected from mushroom farms located in Gauteng, the Western Cape and KwaZulu Natal Provinces of South Africa.Moreover, cobweb disease isolates from the USA and Ireland were included in the study as reference cultures. Isolates were characterised using culture and conidia morphology and were identified as Cladobotryum mycophilum. The isolates were characterised by rapid colony growth between 48 and 72 h on malt extract agar and potato dextrose agar, all but two isolates (GP-15 and KZN-2) produced the pink colour of aurofurasin. All isolates could infect A. bisporus fruiting bodies with varying degrees of aggressiveness. Isolates were sequenced for their ITS, and BLAST analysis showed highest similarity (99-100%) to several ITS sequences of Hypomyces odoratus/C. mycophilum for 35 of the isolates except for one from Ireland that was identified as H. rosellus/C. dendroides. Phylogenetic analysis of the isolates showed South African cobweb disease of mushrooms to be caused by a wide diversity of strains some of which may have originated from elsewhere in the world.

Ten decadal advances in fungal biology leading towards human well-being

et al. 2022

View full text Add to dashboard Cite

Fungi are an understudied resource possessing huge potential for developing products that can greatly improve human well-being. In the current paper, we highlight some important discoveries and developments in applied mycology and interdisciplinary Life Science research. These examples concern recently introduced drugs for the treatment of infections and neurological diseases; application of –OMICS techniques and genetic tools in medical mycology and the regulation of mycotoxin production; as well as some highlights of mushroom cultivaton in Asia. Examples for new diagnostic tools in medical mycology and the exploitation of new candidates for therapeutic drugs, are also given. In addition, two entries illustrating the latest developments in the use of fungi for biodegradation and fungal biomaterial production are provided. Some other areas where there have been and/or will be significant developments are also included. It is our hope that this paper will help realise the importance of fungi as a potential industrial resource and see the next two decades bring forward many new fungal and fungus-derived products.
