Xylaria polymorpha, “Dead Man’s Fingers,” infestation in Boston area?

[Ian David]

this is why I don’t go in the cellar, originally uploaded by kellypuffs.

Well, ONE of the reasons I don’t go in the cellar.

Found this… this… this… I-don’t-know-WHAT coming up from under the cellar floor today.

WTF?!?!?!

They’re creepy, they’re gross, and I want them GONE.

UPDATE: Wicked Smaht flickr users Pete&NoeWoods have identified it as a fungus with a name as disgusting as it looks:

This is Xylaria polymorpha, a fungus. When you hear the common name you really won’t want to go into your basement: “Dead Man’s Fingers”.

Xylaria polymorpha
From Wikipedia, the free encyclopedia

Xylaria polymorpha (Dead man's fingers) is a plant pathogen. It is a common inhabitant of forest and woodland areas, usually growing from the bases of rotting or injured tree stumps and decaying wood. It has also been known to colonise substrates like woody legume pods, petioles, and herbaceous stems. It is characterised by its elongated upright, clavate, or strap-like stromata poking up through the ground, much like a dead man's fingers. The genus Xylaria contains about 100 species of cosmopolitan fungi. Polymorpha means "many forms." As its name suggests, has a very variable but often club-shaped fruiting body (stroma) resembling burned wood.

Often this fungus is found with a multitude of separate "digits" but at times the individual parts will be fused together.

Belonging to the class of fungus known as Ascomycetes (division Mycota) known as the sac fungi, they are characterized by a saclike structure, the ascus, which contains anything from four to eight ascospores in the sexual stage. The sac fungi are separated into subgroups based on whether asci arise singly or are borne in one of several types of fruiting structures, or ascocarps, and on the method of discharge of the ascospores. Many ascomycetes are plant pathogens, some are animal pathogens, a few are edible mushrooms, and many live on dead organic matter (as saprobes). The largest and most commonly known ascomycetes include the morel and the truffle, however the polymorpha is an inedible variety. The dark fruiting body (often black or brown, but sometimes shades of blue/green) is surprisingly white on the inside, with a blackened dotted area all around. This blackened surrounding area is made up of tiny structures called perithecia. The perithecia hold a layer of asci which contain the ascospores. The asci elongate into the ostiole, and discharge the ascospores outward. The spore distribution is a lengthy process, sometimes taking several months to complete this part of the life cycle, this is not a common trait amongst fungi, as is normally a much swifter process.

In springtime this fungus often produces a layer of white asexual spores called conidia, which grow on its surface and surrounding area.

So, it looks like it might be dangerous... or it could be delicious.
