The Ophiostomatales are an order of the sac fungi . Most species colonize wood and bark. Well-known representatives are the causes of Dutch elm disease ( Ophiostoma ulmi and Ophiostoma novo-ulmi ). Ophiostoma piliferum causes hardwood and softwood to turn blue. Most species, however, live as saprobionts , and their spores are often spread by beetles. The anamorphs are partly pathogens in humans ( Sporothrixschenckii ).
features
The order is characterized by individual, black perithecia . In most species they have a long neck from which the sticky ascospores emerge, from where they are spread by insects. This form of the fruiting body is similar to the genus Ceratocystis in the Micoascales . The asci are rounded and resolve early in development.
The anamorphs are hyphomycetes . They belong to the genera Leptographium , Pesotum and Sporothrix .
Systematics
The following families are included in the order (with selected genera and species):
