involved in the meiotic process were more conserved in their expression pattern than non-meiotic genes. These findings indicate ancient conservation of the meiotic process. Human disease Coprinopsis cinerea is harmless to human and animal health under normal conditions. However, the organism can cause opportunistic infections (mycoses) in immunocompromised patients, such as those who have undergone haematopoietic stem cell transplantation or are otherwise undergoing immunosuppression treatment. Most reported cases have been respiratory infections, but cases involving the heart, skin, brain or gut have been reported, and the infections may rapidly become systemic. Whilst exceptionally rare, Coprinopsis cinerea infection is difficult to treat and often fatal in this vulnerable patient group. The infection is caused by the mould-like asexual (non mushroom-forming) anamorph of Coprinopsis cinerea which used to be known as Hormographiella aspergillata, and may be described under this name in the clinical literature.
