Contribución al Estudio de los Aphyllophorales (Basidiomycotina) del Monteverde de las Islas Canarias [Contribution to the Study of Aphyllophorales (Basidiomycota) of Monteverde of the Canary Islands]

About this book

Language: Spanish with bilingual summary in English and Spanish

In all, 245 species of Aphyllophorales have been studied; most were collected over the last few years in the course of this investigation. The ecological impact of the lignicolous Aphyllophorales on the forest ecosystems is of prime importance given their leading role in the biodegradation of cellulose and lignin in wood remains. Analysis of the distribution of the Aphyllophorales by vegetable community yields the following findings: of the 268 species catalogued to date for the whole archipelago, 245 grow in the woods where this study was conducted – the monteverde (laurisilva and fayal-brezal) and mixed transition communities of fayal-brezal-pinewood; 231 develop in the monteverde and/or mixed communities with pinewood (L+FB+PM), 129 of them being exclusive to the monteverde; 14 occur in both pinewoods and mixed pinewoods. To date only 18 species have been assigned exclusively to the Canary pinewoods.

With regard to the substrates on which the forest Aphyllophorales evolved, 217 of the 245 species studied (88.57%) proved lignicolous, and 28 terricolous-humicolous (11.42%) These findings confirm the protagonism to be expected of the Aphyllophorales as lignicolous elements and, in consequence, their great importance in maintaining the balance of the forest ecosystems. Keys for the families, genera and species of the known taxa in the Canary Islands are given in the paper. They also include fungi previously ascribed to the Archipelago but which have not been encountered in the forests under investigation.
