First Cuban record of Pleurotus cystidiosus (Agaricales: Pleurotaceae) and its asexual morph
Journal Title: Revista del Jardín Botánico Nacional - Year 2018, Vol 39, Issue 1
Abstract
The genus Pleurotus (Fr.) P. Kumm. belongs to Pleurotaceae, Agaricales, Agaricomycetes, Basidiomycota. It is a lignicolous genus with a worldwide distribution and causes white rot of wood (Kirk & al. 2008). Its species are edible and has great economic importance for its nutritional and medicinal value (Guzmán 2000), which includes some species that produce synnemata (asexual state) (Stalpers & al. 1991; Seifert & al. 2011). Hawksworth & al. (1995) recognized 50 species for the genus; however, Kong (2004) reported the existence of more than 70 species. This number has dropped to 20 in recent years (Kirk & al. 2008). The authors of “Fungi of the Caribbean” (Minter & al. 2001) recorded 23 species of Pleurotus for insular Caribbean, 12 of them in Cuba. These authors made nomenclatural changes, in which some species were reassignment to other different genera, and just fve are recognized as present in Cuba, with the following current name according Index Fungorum (2017) and MycoBank (2017): Pleurotus albidus (Berk.) Pegler [cited as P. calvescens (Berk.) Singer], P. catephes (Berk. & M.A. Curtis) Sacc., P. djamor (Rumph. ex Fr.) Boedijn, P. ostreatus (Jacq.) P. Kumm., and P. smithii Guzmán. However, the synonymy between Pleurotus cystidiosus and P. smithii has been the subject of discussion due to their similarity in morphology, although some authors separated them by microscopic structures (Guzmán & al. 1991) or by rDNA sequences of the ITS region (Zervakis & al. 2004).
