Pyronema confluens1 occurs on burnt ground or on charred and decayedleaves in woods. Its fruits are pink or salmon-coloured, its mycelium to agreat extent superficial, and its sexual apparatus of unusually large size.The latter fact led to an early study of its development. It was described by de Bary in 1863, by the brothers Tulasne in 1865and 1866, by van Tieghem in 1884, and by Kihlman in 1885, and a veryclear understanding of the morphology of the sexual organs was reached.A swollen,elongated antheridium was recognized and a more or less globular 1 Pyronema confluent.
