Used references: “The D. concentrica group comprises the type species and several related taxa that are typically distributed in mild temperate and subtropical climates of western and southern Europe; some related taxa occur in tropical Africa and in the Southern Hemisphere. They have so far not been found in the Americas and the temperate regions of Asia, despite diligent search. All previous records of “D. concentrica“ from Asia and America obviously need to be revised.” http://www.studiesinmycology.org/...

Xylaria, Daldinia and Bulgaria

Still have to keep with Daldinia concentrica. Xylaria typically is an antler-shaped fungus, seldom more than a few centimeters high, and with white or whitish spore bearing section on the tips. Bulgaria is a mostly gelatinous spring mushroom. Daldinia, in my experience in growing it accidentally on Alnus rubra, starts out dark burgundy red, and quickly matures to a dark brown to blackish lump of very hard growth. Extremely difficult to remove Daldinia from a log unless you also take some of the bark/log with it. Base of stalk is nearly the diameter of the fungus, or somtimes even slightly wider than the fungus. BTW, the Daldinia concentrica I grew was on Alnus rubra inoculated with Lentinula edodes (shiitake). Evidently something in some of the logs conspired to favor the growth of Daldinia over Lentinula, and large masses of this fungus appeared. I don’t remember there being a reddish stain on the wood near where the fungus is growing. But the logs I grew it on still had their bark intact.
