Abstract

Austrobasidium pehueldeni gen. & sp. nov. is described on Hydrangea serratifolia (H. et A.) F. Phil. from Chile. This study adds to the very few reports of Exobasidiales causing formation of stem galls and presents the first species known to parasitise a woody epiphyte and member of Hydrangeaceae (Cornales). A. pehueldeni is compared to the morphologically very similar Laurobasidium lauri (Geyler) Jülich and the systematic position of both species is discussed.


Acknowledgments

The author thanks the Forestry Department of the La Frontera University, Temuco for the permission to perform fungal surveys in the Rucamanque forest reserve, Luciano Figueroa, keeper of the Rucamanque forest reserve for his valuable help during the search for fresh specimens, Dr Roberto Godoy, Valdivia, Gonzalo Tortella, Temuco, and Cesar Donoso, Concepción for the collection of additional material, Dr Angélica Casanova-Katny, Concepción, for the skillful preparation of hand sections, and the team of the laboratory for electron microscopy at the University of Concepción, especially Raúl Alarcón, Hugo Pacheco and Julio Pugin, for their professional technical assistance. The first version of the manuscript was substantially improved thanks to the valuable critical comments of two anonymous referees.
