The gelatinous tears or tear fungi ( Dacrymyces , syn. Arrhytidia, Dacryomyces and Septocolla ) are a genus from the family of gelatinous tears (Dacrymycetaceae) and include species with gelatinous and predominantly pale yellow to bright orange colored fruit bodies . They colonize dead wood and create the substrate , a white rot .
The type species of the genus is the deliquescent gelatinous tear ( Dacrymyces stillatus ).
features
Macroscopic features
The pustular, disc or top-shaped, rarely slightly stalked fruiting bodies have a soft to firm gelatinous consistency (name!). They are colored more or less orange by carotenoids . Gelatinous tears fructify individually or flow together into larger, misshapen structures. The surface is either smooth or wavy.
Microscopic features
The fruiting bodies consist of colorless, buckleless or -bearing hyphae . The hyphae system is monomitic. Hyphidia are either present or absent. The colorless and narrow club-shaped basidia each have two large sterigms (epibasidia). The spores are colorless, often divided by transverse walls and germinate with conidia or germ tubes. Some species have an imperfect stage.
ecology
Gelatinous tears are saprobionts on mostly debarked wood in the early initial to the early final phase of decomposition. If there is enough moisture, they also colonize built-in wood. They cause white rot in the substrate .
species
The genus includes over 30 species worldwide. 16 species occur in Europe or are to be expected there.
