Dactylaria constricta var. gallopava (Cooke) Salkin et Dixon was found to cause fatal encephalitis in a 28-day-old, captivity-bred snowy owl chick (Nyctea scandiaca). The previously healthy bird suddenly developed ataxia, severe torticollis, and extensor rigidity of the legs. Since the animal did not improve with antibiotic or vitamin-mineral supplement therapy, the chick was euthanized 5 days after the onset of neurologic signs. At necropsy, all tissues except the brain were grossly normal. Cultures inoculated with blood from the brain and heart yielded a dematiaceous mould that subsequently proved to be D. constricta var. gallopava. This is the first report of natural central nervous system infection caused by D. constricta var. gallopava in a snowy owl.
发现缢缩指状孢变种gallopava（库克）索尔金和迪克森在一只28日龄人工饲养的雪鸮雏鸟（白鸮）中引起致命性脑炎。这只此前健康的鸟突然出现共济失调、严重斜颈和腿部伸肌强直。由于该动物对抗生素或维生素 - 矿物质补充剂治疗无改善，在出现神经症状5天后对这只雏鸟实施了安乐死。尸检时，除大脑外所有组织大体正常。接种来自大脑和心脏血液的培养物产生了一种暗色霉菌，随后证实为缢缩指状孢变种gallopava。这是缢缩指状孢变种gallopava在雪鸮中引起自然中枢神经系统感染的首例报告。
