trudno w sieci znależć dane o rozmiarach zarodników Daldinia vernicosa. Jest natomiast ciekawa , krótka notka:
http://www.geocities.com/Yosemite/Trails/7331/n98a.html#10 "...Mushroom books that cover Ascomycetes in any detail at all have “cramp balls”, Daldinia concentrica (Bolton: Fries) Cesati and de Notaris; I have 21 books including it. It is the flattened round lumps on wood that start out reddish brown but become black (lasting months). It is easy to identify because cutting a section (which requires a knife -- they're hard) reveals the concentric layers of the Latin name. Adrienne found several reddish brown fungi on a stick in Walking Iron County Park (near Mazomanie in northwestern Dane Co.) on August 9th, and pointed them out to me because they were pretty, in contrast to most finds of Daldinia. I assumed it was young D. concentrica, but although the exterior was firm, the interior had soft greyish gelatinized material between black zones that were nearly perpendicular to the stem, and the larger ones (heads to 3 1.8 cm) had runny liquid in them. In contrast to D. concentrica, these fungi had distinct stems; the smaller ones were almost all stem. It was found immediately to be Daldinia vernicosa (Schw.)Ces. de Not. from the description in Graham, Mushrooms of the Great Lakes Region. It is much harder to find information on this species. The only picture I have is in Cetto, Il fungi dal Vero, Vol. 7, sp. 2982 (rather poor specimens), which is in Italian and not easily available here. Ellis and Ellis, Microfungi on Land Plants includes it, but botch the description so badly it is of no help. They incorrectly say it is specific to genus Ulex (which has 20 species in Europe including gorse and furze, but it only occurs in the US as escapees along the east coast), and fail to mention the gelatinized interior! The only other place I have a description is Breitenbach and Kranzlin, Fungi of Switzerland, Vol. 1 (in the notes for D. concentrica; vernicosa hasn't been seen in Luzerne). D. vernicosa also appears in the Kansas species list in Horn, Kay, and Abel, A Guide to Kansas Mushrooms. I have no idea how common it is in Wisconsin, but I am going to keep an eye out in the future for cramp balls with stems..."
