Candle Snuff Fungus -

Xylaria hypoxylon, also known under the common names "Stag's Horn" or "Candle-snuff Fungus", is the most conspicuous because of its erect 3–7 cm tall -but usually up to 5cm tall-, antler-like ascocarps (fruitbodies) which are black at the base (where the perithecia are embedded) but white and branched towards the top, where the fruitbodies produce white conidia (asexual spores).
