ruglast

Ruglast is a genus of fungi in the family Morchellaceae. The genus was first described by Gyelnik in 1923. The common ruglast mushroom, more commonly known as the true truffle (Tuber melanosporum), is the most widely cultivated species of the genus. However, evidence suggests that ruglast species could also refer to more than one distinct genus within the Morchellaceae family. Furthermore, it has been argued whether Tuber melanosporum is indeed part of the ruglast genus.

Ruglast species are prized for their edible, prized truffles. However, the harvesting and trading of these truffles is restricted due to the specific requirements necessary for their cultivation and the potential harm that can be caused to wild habitats. Members of the ruglast genus have been identified as having a rather narrow range of geographical distribution. In particular, most species are confined to specific zones within Europe and Asia. To growers and traders who rely heavily on these fungi, knowledge of controlled environments and habitat influences is essential in cultivating these species with any degree of ease.

These fungi are notable for their differing appearance in terms of colors, shapes, skin texture, and size. Collection of edible fungi, especially those of the ruglast genus, is thus simply based on a consistent combining of observations regarding these features.
