First, the morphological characteristics Hair Stomach, also known as hair network. The morphological characteristics of cysts group of students, sometimes dense, a handle, oval to cylindrical, top slightly pointed, dark brown or rusty, the total height of 0.7 to 1.5 mm; stalk black, usually shorter than the cysts, rarely reaching full height Of the capsule basement membrane membranous, discoid solitary, or a group of contiguous; capsule axial straight, upward tapering, near the top of the capsular; spore silk dense, curved, dark brown, the main branch thicker branches thinning , More junctions, less free ends, spores spherical, piles of brown, 6.5 to 8 cm in diameter. Second, the danger of symptoms of this slime mold occurred in the bamboo-sun face exposed bare soil or covered in noodles straw, spread rapidly. Dense fungus bacteria Dictyophora bit inside the material to become wet and decay, mycelium growth inhibition or gradual death, culture material there is a large number of bacteria and nematodes,
