Novel Phaeoacremonium species associated with Petri disease and esca of grapevine in Iran and Spain
Mycologia 101 (6), 920-929
Abstract: Eight Phaeoacremonium (Pm.) isolates from grapevines in Iran and Spain were studied with morphological and cultural characteristics as well as phylogenetic analyses of combined DNA sequences of the actin and ß-tubulin genes. Two new species are described. Pm. cinereum was isolated from a young vine in Spain and from older vines in Iran and can be identified by its distinct gray colonies on malt extract agar, an optimum growth temperature of 25 C and subulate type III phialides. Pm. hispanicum was isolated only once from a young vine in Spain and can be identified by the common occurrence of percurrently rejuvenating phialides, an optimum growth temperature of 20 C and predominant type II phialides.
