Hull-less seed squash (Cucurbita pepo subsp. pepo var. styriaca Greb.) has an increasing importance as a plant material to obtain valuable oil and seeds for direct consumption. Its seeds are an important source of organic and inorganic compounds. They have pro-health properties and they are used in treating a number of illnesses. The aim of studies conducted in 2014 was to estimate the species community of fungi occurring on the plants of three cultivars of hull-less seed squash grown in an ecological farm: ‘Junona’, ‘Miranda’ and ‘Gleisdorfer Ölkürbis’. The mycological analysis was made of the roots, stems and leaves (leaf blades together with petioles). The studies showed that fungi Alternaria alternata and Fusarium equiseti most abundantly colonized the leaves and stems of squash in the conditions of ecological cultivation. Species Fusarium oxysporum was most abundantly isolated from the squash roots. In the conditions facilitating their development, these fungi can become pathogenic factors to squash plants. Among the studied cultivars, the Polish cultivar ‘Miranda’ was most abundantly colonized by fungi from genus Fusarium, while species Alternaria alternata was most frequently isolated from the leaves of the German cultivar ‘Gleisdorfer Ölkürbis’.
