Ceuthospora hederae?
Viktorie Halasu, 12-01-2019 14:05
Viktorie HalasuHello forum,

is this correctly identified as Ceuthospora hederae Grove? On leaves of Hedera, conidiomata opening with 2-4 cracks, conidia cylindric, OCI ~ 1 (few tiny LBs at each pole, sometimes also in the middle), non-septate, *(10) 11,7-13,6 (14,6) × (2) 2,4-2,7 (3) ?, with appendix 2,5-4,5 (6) ? long on the lower end, with a congophilous sheath. And is this anamorph of Trochila craterium? I don't have any study in culture or molecular in my literature, any tips are very welcome.

Thank you in advance.
Viktorie

Re : Ceuthospora hederae?
Yes I think it is the Trochila craterium anamorph. In any case it fits the description of C. hederae. I did not have microphotos of this anamorph so far, only macros (see my folder in Cenangiaceae).

As far as I see there is no public genetic proof for this connection.
An incomplete ITS sequence of T. craterium is in GenBank: LT158459,
and SSU V1-V4: KX090886
