What are the control measures for Stereum complicatum on shiitake mushrooms?

Stereum complicatum, also known as Xylobolus frustulatus, belongs to the phylum Basidiomycota, class Agaricomycetes, order Polyporales, family Stereaceae, genus Stereum. This fungus is a large wood-decaying fungus. Its cap is sessile, flat or semicircular, leathery, with a raised base, measuring (2-12) cm x (2-7) cm, often fused to one another, with eggshell-colored or light tea-brown downy hairs, the color gradually fading to smoke-gray, with narrow, smooth, brown or light brown concentric zones appearing, the margin entire or slightly lobed, the hymenium smooth, pale flesh-colored. In nature it mostly grows on decaying wood of broadleaf trees. In log cultivation of edible mushrooms, it damages the logs used for shiitake, wood ear, and silver ear mushrooms, competing with the edible mushrooms for water and nutrients, affecting the growth of shiitake mycelium and reducing yield.

Control methods: When the fruiting bodies of this fungus are found, scrape them off promptly, take them far away from the mushroom yard and bury them deep or burn them, then brush the scraped surface with a 0.1% mercuric chloride solution, and after drying in the shade, brush it with a 1% Bordeaux mixture.
