   Yellow Umbo is a new strain to the mushroom world, created by the great and talented Yoshi Amano. Yoshi created the first ever documented cross between Ps. Cubensis and another species. Yellow Umbo is a cross between Albino Penis Envy and Natalensis. The fruits have unusual stems, similar to the expressions seen on JMF. The caps are small with points tips and yellow flesh.
