Mick PeerdemanIn January i found these black markings on the dea
Could these conidia to belong to the anamorphic state, Hendersonia carpini Sacc., of Splanchnonema carpini?
They are inside conidiomata close to the pseudothecia of the last on Carpinus betulus branches
Thanks again
They may indeed be an anamorphic stage of the Splanchnonema, a fungus I do not know; but these are not the conidia of a Hendersonia in the traditional sense of a fungus with transverse true septa only - your fungus is distoseptate and muriform. It resembles species of Steganosporium (which are indeed anamorphic Splanchnonema).

Chris
Thanks again
Hi Enrique,
yes, this should be Hendersonia carpini Sacc. (a younger homonym of Hendersonia carpini Otth which should represent something different). This species has recently been newly described in Persoonia as Camarographium carpini by Melnik et al. (see attachment). Published sequence data place it within Pleosporales.
Btw, Stegonsporium ("Steganosporium") is not an anamorphic Splanchnonema, but the anamorph of Prosthecium spp. on Acer (Diaporthales), see Voglmayr & Jaklitsch 2008: Prosthecium species with Stegonsporium anamorphs on Acer, Mycological Research 112: 885-905.
best wishes,
Hermann
