Good afternoon.Does anyone know this anamorph?It g
Despite it seemed rather young, I did not found a single ascus in the perithecia, only spores and irregular, hyaline hyphae.
Spores 6-8x3-4 µm, brown (a little olive tinged in KOH), inequilateral; with a long germ slit on the more round side, rather difficult to see. Perisporium separating in KOH.
I think there are no doubts, Hypoxylon ticinense. But I never found it before so a confirmation will be appreciated.
Thanks in advance.
Mario
yes typical ticinense. It's fine you could follow the development over several months.
Jacques
actually at first I had not idea on what it could be...
Now I will try to identify the host; is a dead fallen branch in a mixed wood.

Only a repartition area remark :
It's a very common species here (french basque country).
If you are in a little river, you can find it on all branches fallen in or near the stream.
More common than Scutellinia crinita, if you see what I mean !!
Light orange to yellow-red color is very typical in fact.

The host was Cornus sanguinea. The spot is a mixed wood around a wet area with Alnus glutinosa. Around the alders there are a lot of different trees and shrubs (only broadleaved), and I have found H. ticinense several times, always and only on Cornus, and always on dead branches (standing or fallen) at least 4-5 cm diameter, never seen on twigs.
During the collection I had to saw the wood sometimes; it has a strong and very characteristic smell, as reported by Vittadini, identical to the smell of Tuber brumale!
