Unknown Xylaria from the Tropical House
Maren Kamke, 08-06-2013 08:04
Maren KamkeHello again,
I found this one on wood (Angiospermae) in the Tropical House of the Hagenbeck Zoo in Hamburg.
Coralloid appearence, 3 cm wide and 1,5 cm high, black with resinous exudates at the top of the branches.
Spores ovoid, dark brown with a germ slit (11-13)11,7x4,25(4-5) µm, Asci 110x6, IKI positive, blue porus 4x2µm.
I think it is a Xylaria sp.
Thanks for your help.
Regards Maren
