新发现的稻曲病菌白化菌株其分生孢子座白色，厚垣孢子表面光滑，大小为３．５－６．０×３．５－６．８μｍ。在麦芽糖－稻芽浸渍液中可产生较多的分生孢子。ｐＨ值为６时生长最好。普通培养基中加入几种供试碳源和氮源均有利于菌落生长，以蔗糖为碳源，浓度为２％或以Ｌ－天门冬酰胺为氮源浓度为０．２％～０．３％时时其菌落生长有促进作用。培养过程中可产生对稻种萌发有抑制作用的毒素，而固体培养时产毒能力高于液体培养。白化菌株回接到水稻上可重新产生白色稻曲球。该菌和稻曲病菌的酯酶同功酶和ＲＡＰＤ扩增谱带明显不同。可见白化菌株具有独立于稻曲病菌的新的分类地位。
The newly discovered strains of Ustilaginoideae albino have white conidia and smooth chlamydospores with a size of 3.5-6.0 × 3.5-6.8μm. In maltose - rice bud impregnated liquid can produce more conidia. Growth is best at pH 6. The addition of several test carbon sources and nitrogen sources to ordinary culture medium is beneficial to the colony growth. Using sucrose as the carbon source and the concentration of 2% or L-asparagine as the nitrogen source concentration of 0.2% -0.3 % Of its colony growth has a promoting effect. In the process of cultivation, it can produce toxins that inhibit the germination of rice seeds, while the ability to produce virus in solid culture is higher than that in liquid culture. Albino strain back to the rice can be regenerated white paddy ball. Escherichia coli and Escherichia coli strains of esterase and RAPD amplification bands were significantly different. It can be seen that the albino strain has a new taxonomic status independent of that of Ustilaucoyces.
