This article is a contribution to Lentinus boryanus cultivation, an edible mushroom common in subtropical America, morphologically close to L. edodes (shiitake mushroom). Mycelial growth of two Mexican L. boryanus strains on Carpinus and Quercus sawdust, sugarcane bagasse, sugarcane leaves, and pineapple crown was evaluated. In parallel, monosporic mycelia isolated from these strains were crossed to obtain progeny dykarions. Carpinus sawdust and sugarcane bagasse were chosen for mushroom production essays of parental and progeny strains. A mixture of sorghum grains and Carpinus sawdust (ratio 9:1) was used as spawn. Incubation times fluctuated between 46 and 92 days in Carpinus sawdust and between 59 and 124 days in bagasse sugarcane. Primordia initiation was observed between 110 and 181 days in Carpinus sawdust and between 78 and 151 days in sugar cane bagasse. The average of biological efficiency reached from 2 to 3 harvests fluctuated between 7.1% and 24.9% in Carpinus and between 6.8% and 15% in sugarcane bagasse, parent strain (IE-193) being the most frequently yielded on both substrates, and correspondingly, the biggest basidiomes were developed for the progeny strain (C-15) in sugarcane bagasse.
