Xylaria hypoxylon is an inedible species of fungus in the genus Xylaria. It is known by a variety of common names, such as the candlestick fungus, the candlesnuff fungus, carbon antlers,[1] or the stag’s horn fungus.[2] The fruit bodies, characterized by erect, elongated black branches with whitened tips, typically grow in clusters on decaying hardwood. The fungus can cause a root rot in hawthorn and gooseberry plants.[3]

Fruit bodies (ascocarps) are cylindrical or flattened with dimensions of 3–8 centimetres (1.2–3.1 in) tall × 2–8 mm thick.[1] The erect ascocarps are often twisted or bent, and typically sparsely branched, often in a shape resembling an antler’s horns. Specimens found earlier in the season, in spring, may be covered completely in asexual spores (conidia), which manifests itself as a white to grayish powdery deposit. Later in the season, mature ascocarps are charcoal-black, and have minute pimple-like bumps called perithecia on the surface. These are minute rounded spore bearing structures with a tiny holes, or ostioles, for the release of sexual spores (ascospores). The perithecia are embedded in the flesh of the ascocarp, the stroma, which is tough, elastic, and white. Within the perithecia, the asci are 100 × 8 µm.[6]
Ascospores are kidney-shaped, black, and smooth, with dimensions of 10–14 × 4–6 µm.[7] The asexual spores (mitospores) are ellipsoid in shape, smooth, and hyaline.[8]
Although not poisonous, the small size and tough texture of this fungus deter consumption. 
Xylaria polymorpha is thicker and not as branched as X. hypoxylon.

Xylaria polymorpha, i hope !!

I think it is Xylaria hypoxylon, commonly known as candle snuff fungus because of its characteristics black and white appearance like an extinguished candle-wick.
These is a perithecial fungus. This sp. produce antler-shaped structures (0.03 – 0.05 cm dia) as can be seen in the pic but X. polymorpha produces irregularly club-shaped structures about 1-3cm in diameter.

Can you pls help me in identifying species of these fungi. They were photographed in Deer Park, Hauz Khas, New Delhi in July/ August 2008.
First one is Xylaria. I think X. polymorpha. Want confirmation.
 ………………………….

 

  1. The first picture is of Xylaria polymorpha (Pers.) Grev., (1824) (Xylariaceae) indeed but the stroma is still imatured when the photo was taken hence it is still to take the perfect club shaped structure and the black colour, I west Bengal I don’t why this fungus tens to grow more on Guava tree trunk. 
  2. …………………………

These are Xylaria polymorpha, ……………. respectively beyond any doubt.

Thanks for the confirmation.

This image looks more closer to images at Xylaria hypoxylon (L.) Grev.
