1. Large-scale fungal identification, culture, and production.
A major technical barrier hampering the study of fungal sensitization is the lack of stable, well-defined fungal material in sufficient amounts. A further issue is the high diversity of fungal spore morphology and subsequent difficulties in identification, which is more complex when compared with pollen. Involving highly specialized laboratories and networks with expertise in the discovery, identification, and optimal culture of environmental fungal genera and fungal allergy investigation is needed.
