Taxonomy of Pseudolagarobasidium (Polyporales, Basidiomycota)

  • Karen K. Nakasone
  • Daniel L. Lindner


Pseudolagarobasidium (Polyporales, Basidiomycota) is a small, monophyletic genus of crustose, wood-inhabiting fungi with spines and a saprobic, endophytic, or parasitic habit. Seven species are accepted in the genus including two new species, P. belizense from Belize and P. pusillum from Australia. Sequence analysis of the internal transcribed spacer of the ribosomal RNA gene places P. belizense in a monophyletic clade with P. acaciicola and an undescribed foliar endophyte. New combinations proposed include P. modestum for Irpex modestus Berk., P. pronum for Hydnum pronum Berk. & Broome which is an earlier name for P. calcareum, and P. venustum for Radulodon venustus Hjortstam & Ryvarden. Irpex colliculosum Berk. & Broome from Sri Lanka is conspecific with P. subvinosum. Two species, Sistotrema ochroleucum and Radulum concentricum are not accepted in Pseudolagarobasidium. Pseudolagarobasidium is compared with Radulodon and similar genera. A key to the species of Pseudolagarobasidium is provided.

We thank the curators of BPI, H, K, NY, O, PERTH, PREM, S, and TFM for their assistance in arranging specimen loans. Kyah Norton assisted in obtaining DNA sequences of P. belizense. Fieldwork in Belize was made possible by a grant from the National Science Foundation, Biodiversity Surveys and Inventories Program to Dr. T.J. Baroni, the State University of New York, College at Cortland (DEB-0103621), in collaboration with Dr. D.J. Lodge and the Center for Forest Mycology Research, Northern Research Station, U.S. Forest Service. Dr. Lodge helped coordinate logistical support for the field work in Belize, and the British Forces of Belize provided airlift transportation to Doyle’s Delight Peak in the Maya Mountains. Alan Whitelaw, the commanding officer of the Belize Forces, and Sharon Matola, Director of the Belize Zoo, were responsible for making the expeditions possible. Several other individuals with government and nongovernmental agencies in Belize are kindly acknowledged for their help and guidance: Hector Mai, John Pinelo, and Natalie Rosado of The Conservation Division, Belize Forestry Department, Belmopan; and Celso Poot, Station Manager of the Tropical Education Center in Belize. Drs. S.P. Gorjón and J. Stalpers reviewed an earlier draft of the manuscript.
