Hemagglutinating activity in extracts of mycelia from submerged mushroom cultures

Extracts from mycelia of seven different mushrooms agglutinated erythrocytes of several species. More than one agglutinating factor was identified in the extracts of three different mycelia. Agglutination was partially inhibited nonspecifically by high concentrations of glucose, galactose, mannose, fucose, and rhamnose.
