Examination of isolates of Hymenoscyphus albidus from France revealed that this fungus does not form an anamorphic stage in culture. The lack of an asexual stage in this fungus is a conspicuous morphological difference to the ash dieback pathogen Hymenoscyphus pseudoalbidus, which is associated with its Chalara fraxinea anamorphic state. In growth studies on malt extract agar (MEA) and MEA amended with ash leaflets (ash leaf malt extract agar, AMEA) at 20°C, isolates of H. albidus grew slower than those of H. pseudoalbidus. On AMEA, the growth of cultures of both species was greatly enhanced.
