DALDINIA CONCENTRICA PDF

He fell asleep and the cakes burned. Many types of insects and other small animals make their home inside this species of fungus. It is also believed by some authorities that the alder wood wasp is involved in the dispersal of spores. During spring 2it can be found covered in a layer of sooty black spores ; these are released at night and can travel up to 2 cm away from the concentruca body from which they were discharged. Black ascospores are ejected from these openings in great numbers, covering the surface of the fruit body and nearby surfaces.

Its small, tough fruiting bodies are shaped more or less like a ball, and feature a crust-like, brown to black outer surface. When sliced open, the carbon-like flesh is concentrically zoned with alternating bands of whitish to grayish and black. Daldinia childiae appears on decaying logs, fruiting directly from the wood. Your North American field guide is likely to call the mushroom featured here "Daldinia concentrica," but the true Daldinia concentrica is a European species partial to the wood of European species of ash, and is either absent in North America or extremely rare.

Its crusty outer surface releases purple pigments when ground up and soaked in KOH , while the crust of Daldinia childiae releases brown pigments. Thanks to Cecily Franklin for collecting, documenting, and preserving Daldinia childiae for study; her collection is deposited in The Herbarium of Michael Kuo. Description: Ecology: Saprobic on decaying hardwood logs and, infrequently, conifer logs; growing alone or gregariously, directly from the wood; spring through fall or over winter in warm climates —but the tough fruiting bodies often last over winter; widely distributed in North America, but especially common east of the Rocky Mountains.

The illustrated and described collections are from Illinois, North Carolina, and Pennsylvania. Fruiting Body: 7—32 mm across; 10—20 mm tall; shaped more or less like a ball, cushion, or pear; sometimes featuring a poorly defined pseudostem ; surface hard, smooth at first, becoming pimply, pinkish brown, reddish brown, dark brown or, eventually, nearly black; interior with concentric zones of blackish and whitish or grayish, carbon-like flesh; outer layer at maturity with embedded black perithecia.

Daldinia concentrica

They are also referred to as Cramp Balls because carrying them was thought to cure attacks of cramps. These hard, inedible fungi appear most often on ash and beech wood but occasionally on other hardwood trees. The pinkish-brown specimens shown above are young and still growing, and during this asexual stage they develop over a long period and release pallid, almost colourless spores known as conidiospores or simply as conidia , which are pinkish white when seen in mass. Once fully grown the fruitbodies turn black, like those in the picture above. At this mature stage the surface becomes dotted with tiny bumps that are the openings of perithecia, the spore-producing structures located just below the surface. Ascospores, which unlike the pallid conidiospores are jet black, are ejected from these openings in vast numbers, soon covering the surface of the fruitbody and darkening the substrate wood creating in effect a natural spore print for some distance around it.

Since all we had at my house was natural gas heat, I remember once getting charcoal briquettes from the grill in my stocking One of the British names, "cramp balls," is not so obvious. That name is thought to have arisen from the widespread belief that carrying this fungus in your pockets would prevent or relieve leg cramps.
