Literature request: Tympanis on Fraxinus
Eduard Osieck, 28-06-2015 12:32

Does somebody has available:
Cannon & Minter 2013 Tympanus columnaris
IMI Descriptions of Fungi and Bacteria, 2013, 195, pp Sheet 1948
and/ or
GROVES J.W. 1952. The genus Tympanis. Can. J. Bot. 30: 571-651.

Recently I found a Tympanis on Fraxinus which could be T. columnaris (not included in the Danish/ German key) . Asci 120-130 x 10 mu containing vaguely visible "secondary spore balls" about 15 x 8 mu. Secondary spores ellipsoid about 6 x 3 mu. 

Thanks in advance, Eduard

Hello Eduard
Paul Cannon does visit this forum quite regularly so he might be able to provide the first. I have sent you the CJB one via Dropbox . . .

Re : Literature request: Tympanis on Fraxinus
Chris, thank you very much!
Unfortunately the collection cannot be identified properly with the key of Groves and the asci appear to be less wide than indicated by Groves for T. columnaris. So I am quite anxious to see the description by Cannon & Minter.
