Dry rot fungus, SEM
Dry rot fungus. Coloured scanning electron micrograph (SEM) of dry rot in a piece of domestic plywood. Dry rot is a fungus (Serpula lachrymans) which infects damp timber. As the fungal network, or mycelium, grows, it destroys the cellulose in the wood and weakens its structure. The mycelium consists of strands known as hyphae, the thin threads seen here. The thicker objects are fragments of wood

EDITORS COMMENTS
This print showcases the intricate world of dry rot fungus, revealing its destructive nature within a piece of domestic plywood. The vivid colors in this false-colored scanning electron micrograph (SEM) highlight the biological marvels at play. Dry rot, caused by the Serpula lachrymans fungus, thrives in damp timber and gradually erodes the cellulose that forms wood's structural integrity. The image unveils an expansive fungal network known as mycelium, composed of delicate strands called hyphae. These thin threads intertwine and spread throughout the wood, acting as agents of decay. As they grow and digest cellulose, they weaken the plywood's structure from within. Amongst this mesmerizing scene are fragments of deteriorating wood captured by the SEM. These remnants serve as a reminder of dry rot's relentless assault on its host material. Through this photograph, we gain insight into a hidden realm where biology meets destruction. It offers us a glimpse into the fascinating field of mycology while emphasizing how crucial it is to protect our wooden structures from such insidious fungi. This remarkable image is courtesy of Science Photo Library—a testament to their commitment to capturing scientific wonders with artistic precision and sharing them with curious minds worldwide.
