粉红粘帚霉 (英语：Gliocladium roseum) 是一种真菌,无性型为: 粉红螺旋聚孢霉 (英语：Clonostachys rosea)。 它作为内生真菌定植在活的植物内，作为腐生生物消化在土壤中的材料，也在被称为线虫的其他真菌的寄生生物。

被发现于南美的巴塔哥尼亚（阿根廷和智利）雨林树上的一种粉红粘帚霉能释放一种成分与柴油相似的挥发物，有望成为生物燃料的一个新来源。 粉红粘帚霉可以直接利用纤维素合成微生物柴油。这意味着我们可以在不消耗粮食的情况下有希望直接生产出生物燃料。

Clonostachys rosea f. rosea, also known as Gliocladium roseum, is a species of fungus in the family Bionectriaceae. It colonizes living plants as an endophyte, digests material in soil as a saprophyte and is also known as a parasite of other fungi and of nematodes. It produces a wide range of volatile organic compounds which are toxic to organisms including other fungi, bacteria, and insects, and is of interest as a biological pest control agent. The volatile emissions of one strain, found growing in the ulmo trees in the rainforests of Patagonia (Argentina and Chile), have been said to resemble diesel, and thus to be a potential biofuel.
