Stictis

Stictis is a genus of fungi in the family Stictidaceae. Most species are saprotrophic decomposers that inhabit dead wood, where they form small, flask-shaped fruiting bodies that remain largely embedded within their substrate and open through tiny pores. The genus is characterised by its distinctive white, frost-like rim that surrounds the fruiting bodies and thread-like ascospores divided by multiple cross-walls. Modern molecular phylogenetics studies suggest that the current broad concept of Stictis will likely be split into several separate genera as the group undergoes taxonomic revision....read more on Wikipedia.
