Fruiting bodies 6–15 cm in length, 0.5–1 cm in broad (Fig. 1), growing either singly or in groups which are typically seen emerging from soil, dark brown, becoming darker at maturity. Stromata with fertile part is cylindrical-clavate, with rounded, fertile apices, unbranched, single or clustered, shortstipitate, stipe smooth and black. External surface is blackish with golden brown scales,
roughened with small wrinkles, internally white and occasionally becoming hollow. Perithecia completely immersed, up to 0.5 mm
diam., ostioles black, papillate (Ramesh et al., 2012).

Habitat and Ecology
Substrate is undetermined decaying wood. Growth rate is high, 5.8–7.5 cm/week, covering petri dish in 6–8 days. Mycelial mat is white at early stage, later it is brown to black coloured. Hyphae are thin-walled and branched. The fruiting bodies arise in the spring. They may persist for several months or even years and can release spores continuously during this time.
Subtropical/Tropical Moist Lowland ForestOther
In Brazil the species was registered in an environmental protection area, but it is an area that suffers from anthropogenic actions.
Housing & urban areasTourism & recreation areas
Species found in environmental conservation area in Brazil. But like other species it needs preservation together with the beings with which it is associated.
The genus Xylaria presents many complexes that are not well defined, taxonomic and phylogenetic studies are needed to better define their species.
