Introduction: Since time immemorial, mushrooms have been used as a part of human diet, some of them are very well known for their nutritive and medicinal properties and some are known to cause poisoning to the human body. A number of post ingestion fatalities due to poisonous mushrooms has been reported worldwide. These poisonous mushrooms are often misidentified as edible ones, which accounts for accidental poisoning.Objective: The main objective of this report was to describe the clinical manifestations of mushroom poisoning cases presented at the Emergency Department (ED), Taiping Hospital.Case Presentation: There were two cases presented, who suffered from moderate dehydration due to acute gastroenteritis after taking 'delicious mushrooms', also known as Chlorophyllum Molybdites. This study found that both cases had complaints of abdominal cramping, diarrhoea and vomiting more than twenty times a day. There was no history of numbness or weakness noted, and no chest pain or shortness of breath. On arrival, both cases presented signs of moderate dehydration with coated tongue and normal blood pressure, with slightly increased in temperature (37.30C). Abdomen was soft but discomfort upon palpation and described as bloated. Both cases were resuscitated with 20ml/kg normal saline. Charcoal, antiemetic, proton pump inhibitor and ceftriaxone antibiotic were given at the ED. Both survived and were treated as infectious acute gastroenteritis. Nausea and vomiting were the most common early symptoms of intoxication and should be considered as a medical emergency. Alpha Amanitin levels should be checked where possible if amanita poisoning is suspected. An early diagnosis and immediate treatment are required for a successful outcome.Conclusion: All patients with the history of mushroom ingestion should be admitted. If laboratory detection of toxin is not available, history of mushroom ingestion, clinical manifestation and their trends could define mushroom poisoning.International Journal of Human and Health Sciences Supplementary Issue: 2021 Page: S17

This research aims to develop a classification model for edible and poisonous mushrooms by applying the feature selection approach together with the decision tree technique. Two feature selection methods were applied, including 1) Chi-square and 2) Information Gain, while the effectiveness of the model was compared by three decision tree methods such as Iterative Dichotomiser3, C4.5 and Random Forest. The data used for classifying the edible and poisonous mushrooms derived from the Encyclopedia of Thai mushrooms and the book entitled “Diversity of Mushrooms and Macrofungi in Thailand”. The results of the model’s effectiveness evaluation revealed that the model using the Information Gain technique alongside with the Random Forest technique provided the most accurate classification outcomes at 94.19%; therefore, this model could be further applied in the future studies.

Among 276 species of class Agaricomycetes isolated from the Ngoc Linh mountain, Quang Nam Province, we identified and recorded eight new species of macrofungi in Vietnam, namely Cymatoderma caperatum, Amanita xanthogala, Chlorophllum brunneum, Chlorophyllum hortense, Hymenopellis megalospora, Psathyrella longipes, Russula cystidiosa, and Serpula lacrymans. The morphologies, anatomical characteristics as well as applications of these species were demonstrated. Among these 8 newly recorded species in Vietnam, 2 species are edible mushrooms and 3 another species may be poisonous mushrooms.

We identified and documented 8 spicies as new to macrofungi of Vietnam, of 7 genus, 7 family, 4 ordo, belonging to classes of Agaricomycetes, of which 2 species of edible mushrooms, 3 species poisonous mushrooms and 3 species of wood destruction, quickly formed humus for the soil environment.. New species recorded for the large fungal colonies of Vietnam have been studied for morphological and microscopic characteristics.

The consequences of mushroom poisoning range from mild, mostly gastrointestinal, disturbances to organ failure or even death. This retrospective study describes presentations related to mushroom poisoning at an emergency department in Bern (Switzerland) from January 2001 to October 2017. Gastrointestinal disturbances were reported in 86% of the 51 cases. The National Poisons Information Centre and mycologists were involved in 69% and 61% of the cases, respectively. Identification of the mushroom type/family was possible in 43% of the cases. The most common mushroom family was Boletaceae (n = 21) and the most common mushrooms Xerocomus chrysenteron (n = 7; four being part of a cluster), Clitocybe nebularis, Lepista nuda and Lactarius semisanguifluus (n = 5 each, four being part of a cluster). Poisonous mushrooms included Amanita phalloides (n = 3, all analytically confirmed), Boletus satanas (n = 3), Amanita muscaria (n = 2) and Amanita pantherina (n = 2). There were no fatalities and 80% of the patients were discharged within 24 h. Mushroom poisoning does not appear to be a common reason for emergency consultation and most presentations were of minor severity and related to edible species (e.g., due to incorrect processing). Nevertheless, poisonous mushrooms and severe complications were also recorded. Collaboration with a poison centre and/or mycologists is of great importance, especially in high risk cases.

The indigenous people in Chakrata have an immense knowledge of edible and poisonous mushrooms.  In the present study the use of mushroom in culinary practices was surveyed among three communities, viz., the natives: Brahmins, Kshatriyas and Scheduled Caste; and Nepali immigrants.  The Brahmins & Kshatriyas showed a narrow range of consumption of mushrooms while the Nepalis showed the widest range of consumption.  Medicinal and religious uses were reported by the scheduled caste.  A total of 63 mushrooms were recorded from the study area.  The knowledge of edible as well as medicinal uses of fungi is at risk in this region as the younger generation is not willing to learn this traditional knowledge.  In the present study most of the youths were excluded at the end as they did not gave much information.
