The allergenic significance of certain fungi rarely reported as allergens

The allergenic significance of seven different species of fungi was investigated. Included were Chlorophyllum molybdites, Podaxis pistillaris, Stemonitis ferruginea, Lycogala epidendrum, Fuligo septica, Ustilago maydis and Puccinia cynodontis. All of these fungi have wide distribution patterns and aerially disseminated spores but, because of their unique growth characteristics, are usually not reported in atmospheric fungal surveys. Seventy-eight patients were treated for dermal sensitivity to extracts of the organisms after the spores were extracted in 50% glycerinated Coca's solution. The results represent a six-month test period. Forty-four patients, representing 56% of the total number tested, demonstrated dermal reactivity toward one or more of the extracts.
