Boletus luridellus (Murr.) Murrill and Quercus fusiformis Small: pure culture, synthesis of mycorrhizas and sporocarp production in nursery

Abstract

This study documents the first register of Boletus luridellus (family Boletaceae) in the states of Nuevo León and Tamaulipas. Pure cultures were obtained in vitro; synthesis of mycorrhizae was achieved with Quercus fusiformis, and fruiting bodies were produced under greenhouse conditions for the first time. This species forms mycorrhizae with Quercus fusiformis, Q. polymorpha and Q. canbyi, in its natural environment. This species has a good potential for inoculation of oak seedlings in order to obtain better seedling growth under greenhouse conditions in northeastern Mexico, where oaks are currently planted in urban gardens, parks and new urban developments. This symbiosis is interesting because it occurs in a dry geographic zone where temperatures are high during the summer. Boletus luridellus is reported to be an edible species that grows well and produces sporocarps on a yearly basis (another experiment) in the gardens of the School of Forest Science in Linares, Nuevo León.
