Myxarium Hyalinum
''Myxarium'' is a genus of fungi in the family Hyaloriaceae. Basidiocarps (fruit bodies) are gelatinous and effused or pustular. The genus is cosmopolitan. All species grow on dead wood or dead herbaceous stems. Taxonomy History The genus was originally described by Karl Friedrich Wilhelm Wallroth in 1833 based on the visible white inclusions in the basidiocarps of the type species, ''Myxarium nucleatum'', which he interpreted as spores (they are in fact crystals of calcium oxalate). The genus was synonymized with ''Exidia'' by subsequent authors, until revived by Dutch mycologist M.A. Donk in 1966. The revised concept of ''Myxarium'' emphasized the microscopic presence of septate basidia with enucleate stalk cells ("myxarioid" basidia), a feature absent in ''Exidia''. Additional species were added to the genus on this basis.
