Entomophthora muscae (fly fungus) Stourbridge Common

Life cycle
Soon after a fly dies from infection with this pathogenic fungus, large primary conidia are produced at the apex of a conidiophore which emerge from the intersegmental membranes. When the spores are mature they are forcibly ejected and may fall onto flies resting nearby. If no hosts are available for infection, a smaller secondary conidium may develop. The conidia germinate within a few hours and a germ tube begins to penetrate the insect’s cuticle. Once this reaches the haemocoel, the protoplast flows through the tube and into the fly’s haemolymph. The mycelium of the fungus may grow into an area of the brain that controls the behaviour of the fly, forcing it to land on a surface and crawl upwards. The hyphae gradually grow through the whole of the body, digesting the guts, and the fly dies in about five to seven days.When it is critically ill, it tends to crawl to a high point, straighten its hind legs and open its wings, a behaviour that ensures that the fungal spores are dispersed as widely as possible. Some three hours later, conidiophores start to develop and a new shower of conidia is initiated.

Ice Hair fungus (Aberfoyel)


On humid winter nights, you may be able to find these peculiar ice crystals that form on Rotting Wood..
Looking a little like fur, or candyfloss, these hair-like whisps appear overnight and then melt when the sun comes up..
Hair ice is caused by a fungus called Exidiopsis effusa, and the action of this fungus is to enable the ice to form thin hairs – with a diameter of about 0.01mm – and to keep this shape over many hours at temperatures close to 0°C,
