The equine phycomycotic agent known commonly as Hyphomyces destruens or occasionally as Pythium gracile, is described as a new species Pythium destruens. Separation is on the basis of morphological features, temperature growth profiles, esterase/lipase activity, and carbohydrate utilization ability. P. diclinum (synonymous with P. gracile sensu Middleton) showed minor differences in vesicle, oospore and oogonium size from P. destruens. P. destruens grew at 40 degrees C on corn meal agar and hydrolysed esters of lauric and oleic acids. These abilities were not displayed by P. diclinum, but this species grew more vigorously on cellobiose, fructose, gentibiose, inulin, raffinose, maltose, mannose, salicin, starch and sucrose than P. destruens. The latter species showed no substantial ability for growth on inulin, raffinose, and salicin. Equine isolates from Australia, Japan and New Guinea were similar.
通常被称为毁灭丝霉菌或偶尔被称为纤细腐霉的马藻状菌病原体，被描述为一个新物种——毁灭腐霉。分类是基于形态特征、温度生长曲线、酯酶/脂肪酶活性以及碳水化合物利用能力。双性腐霉（与米德尔顿所定义的纤细腐霉同义）在泡囊、卵孢子和藏卵器大小方面与毁灭腐霉存在细微差异。毁灭腐霉能在玉米粉琼脂上于40摄氏度生长，并能水解月桂酸和油酸的酯。双性腐霉不具备这些能力，但该物种在纤维二糖、果糖、龙胆二糖、菊粉、棉子糖、麦芽糖、甘露糖、水杨苷、淀粉和蔗糖上比毁灭腐霉生长得更旺盛。后者在菊粉、棉子糖和水杨苷上基本没有生长能力。来自澳大利亚、日本和新几内亚的马分离株相似。
