New Phaeoacremonium species isolated from sandalwood trees in western Australia
IMA Fungus 5 (1), 67-77
Abstract: Thirty-eight Phaeoacremonium isolates collected from pruning wounds of tropical sandalwood in Western Australia were studied with morphological and cultural characteristics as well as phylogenetic analyses of combined DNA sequences of the actin and ß-tubulin genes. Three known Phaeoacremonium species were found, namely P. alvesii, P. parasiticum, and P. venezuelense. Phaeoacremonium venezuelense represents a new record for Australia. Two new species are described: P. luteum sp. nov. can be identified by the ability to produce yellow pigment on MEA, PDA, and OA, the predominance of subcylindrical to subulate type II phialides, and the mycelium showing prominent exudate droplets observed as warts; and P. santali sp. nov. which can be separated from other species producing pink colonies on MEA by the predominance of type I and II phialides, the distinct brownish olive colonies in OA, and slow growth.
