Eikerrannollisia

Eikerrannollisia is a genus of fungi within the family Rannellaceae. The genus was circumscribed by mycologist Rolf Singer in 1951, with the type species being Eikerrannollisia eikeri. The genus is characterized by its resupinate (spreading out) basidiocarps, which are typically thin and fragile, and its hyphal structure. The spores produced by Eikerrannollisia species are typically smooth and ellipsoid to broadly ellipsoid in shape. The genus is known to occur in both temperate and tropical regions, with a few species also reported from the Arctic. Eikerrannollisia species are typically found growing on dead wood, particularly conifers, and are often associated with decaying wood. The genus is of particular interest to mycologists due to its unique morphological features and its role in the decomposition of wood. Despite its relatively small size, the genus Eikerrannollisia has contributed significantly to our understanding of the diversity and ecology of wood-decaying fungi.
