Mycosis of the mushroom crop F. J. GEA ALEGRÍA and J. TELLO MARQUINA

An inventory of fungal diseases of mushroom cultivation, carried out during the years 1986 and 1991-2, is presented. In this inventory a total of 16 taxa are cited, among them, the main fungal pathogens of the crop, such as: Cladobotryum dendroides, Diehliomyces microsporus, Mycogone perniciosa, Trichoderma spp. and Verticilium fungicola. During this biennium, an assessment was made of the most important phytopathological problem: Mole seca disease, which was present in all the farms and crop cycles sampled. This assessment showed that 67.72% of the diseased carpophores collected showed symptoms of being parasitized by V. fungicola, a fact that was corroborated by isolating the pathogen from 74.33% of the diseased carpophores analyzed. The exponential growth of the mycosis throughout the harvesting period was also evident, so that during the first blossoms it can go practically unnoticed, while from the fourth blossom onwards the damage becomes more evident.
