Pleurotus ostreatus
In Canada, 8% of children attending allergy clinics were found to be allergic to Ganoderma, a basidiospore. Pleurotus ostreatus, cladosporium, and "Calvatia cyathiformis" are significant airborne spores. Other significant fungal allergens include aspergillus and alternaria-penicillin families. In India "Fomes pectinatus" is a predominant air-borne allergen affecting up to 22 percent of patients with respiratory allergies. Some fungal air-borne allergens such as "Coprinus comatus" are associated with worsening of eczematous skin lesions. Children who are born during autumn months (during fungal spore season) are more likely to develop asthmatic symptoms later in life.
