Lactarius in Northern Thailand: 1. Lactarius subgenus Piperites

Abstract

This paper reports on Lactarius subgenus Piperites from northern Thailand and is the first in a series resulting from a complete revision of the genus for the area. Five taxa are described as new for science: Lactarius formosus, L. austrotorminosus, L. austrozonarius, L. alboscrobiculatus and L. alboscrobiculatus var. roseopurpureus. Three other new species are described and illustrated, but not formally described. Lactarius akahatsu and L. hatsudake, described from Japan, are recorded for Thailand, and L. purpureus, described from Thailand in 1966 is also listed here with new records. Species concepts and comparisons with species of other continents are based on morphological and molecular data (ITS-region).
