Morphological characteristics of different fungi on the plate

      The evaluation criteria of culture plate fungi can be carried out through the following 

aspects: the color, density, and fluffiness of aerial hyphae, the concentric or radial shape 

of hyphae, the presence of spots, the presence of dark secretions (such as secretions of 

Phellinus linteus, Ganoderma lucidum, and Boletus edulis), the degree and size of hyphae

wrapping in the inoculated block, the size of the colony, the uniformity of the edges (such as

 missing corners, serrations, and irregular shapes), the presence of powder spores (such as

 Flammulina velutipes and Pleurotus eryngii), thick-walled spores (such as Volvariella volvacea 

and Agaricus variegata), whether the bottom culture medium is dry and cracked (such as Boletus 

edulis and Pleurotus eryngii), and whether primordia occur (such as Pleurotus eryngii)
