Language: Spanish
Species, varieties and forms belonging to the genus Leccinum are described. Some of them, namely:
- L. brunneogriseolum
- L. cyaneobasileucum
- L. umbrinoides
- L. nucatum
- L. scabrum var. melaneum
- and L. duriusculum fo. robustum
are included because they are rare or little known taxa, while others, even though much commoner, are added because they are generally misinterpreted or little studied. A key for the determination of the above taxa is also presented.
