Extract from Wikipedia article: Hypomyces hyalinus is a species of parasitic fungi that attacks fungi of the genus Amanita. The earliest recording of this parasite was in 1822 in Salem, North Carolina, but microscopic descriptions of H. hyalinus do not appear in the literature until 1886.
AI-generated description
Hypomyces hyalinus is a parasitic fungus that infects mushrooms, particularly species of Amanita, Boletus, and Russula. In East and Central Texas, it has been found to occur on various host species, including Amanita texensis and Boletus rubroflavus. The fungus forms a white to pale yellow, waxy to gelatinous coating over the surface of the infected mushroom, often causing deformation or distortion of the host's cap and stem. It produces perithecia that are partially to fully immersed in the stroma, with ascospores measuring 35-50 μm in length. Hypomyces hyalinus has been collected from various habitats in East and Central Texas, including wooded areas, parks, and nature reserves, typically during the summer and fall months when its host species are most active.
