Nine new records of boletes (Boletales, Hymenomycetes) From Nam Nao and Phu Rua National Parks, Thailand

Abstract

Bolete fungi from Nam Nao and Phu Rua National Parks, Thailand were collected during the wet seasons of 2005 and 2006 in order to investigate their species diversity. There were fifty-two specimens, 40 from Nam Nao and 12 from Phu Rua, which were collected, photographed and examined morphologically at both macroscopic and microscopic levels. The collected specimens, belonged to nine genera as follows: Boletellus, Boletus, Heimiella, Leccinum, Phylloporus, Pulveroboletus, Strobilomyces, Tylopilus and Xerocomus. Nine species reported here are new records to Thailand. They are Boletus laetissimus Hongo, Boletus obscureumbrinus Hongo, Boletus subvelutipes Peck., Heimiella japonica Hongo, Leccinum extremiorientale (L. Vass) Sing., Phylloporus cf. rhodoxanthus (Schw.) Bres., Strobilomycesconfusus Sing., Tylopilus eximius (Peck) Sing. and Xerocomus subtomentosus (L.:Fr.) Quel. P. cf. rhodoxanthus is the only species that needs more detailed study.
