瓜笄黴學名Choanephora cucurbitarum)是一種植物病原真菌,屬於毛黴目英语Mucorales,可引起各種葫蘆的果實和花朵腐爛。它也可能會影響秋葵敏豆豇豆,且可能導致睡茄腐敗。2017年,Das等人在對印度的茄子凹萼木鱉扁豆豌豆進行研究後,增加了更多關於瓜笄黴的病理指標。瓜笄黴好發於高溫高濕的環境,並且會在土壤中盤據。瓜笄黴主要的病徵是會感染果實及葉子,其中包含水浸狀的病徵或壞疽型病斑,且發展快速。當真菌開始產生孢子時,受影響的植株組織會因孢子囊遍佈而呈灰褐色及毛茸狀。

性狀描述[编辑]

瓜笄黴帶有小孢子囊(sporangiola)的孢子囊柄直立、透明且無分枝,頂端膨大長出棒狀囊泡,從囊泡中產生二分枝狀,亦呈棍棒狀的二級囊泡。小型孢子囊為不開裂的,呈橢球狀,顏色為棕色至深棕色,具有明顯的縱向條紋,尺寸為12-20μm x 6-12μm。孢子囊呈球狀,含有多枚孢子,最初的顏色為白色至黃色,成熟時呈淺棕色至深棕色,尺寸為40-160μm。來自孢子囊的孢子囊柄呈橢圓形至寬橢圓形,顏色為棕色至深棕色,具有細小透明極性附屬物的不透明條紋,尺寸為16-20 µm x 8-12 µm。[1]
