Leucostoma on Prunu sp.

Hi to all

Could this fungus be Leucostoma persoonii or some close species of this genus? It grew on Prunus sp. branches at 1000 m ofaltitude. I don't know its Cytospora anamorphic state.

Do you know some modern keys of Leucostoma?
Thanks again

Re : Leucostoma on Prunu sp.
Hello Enrique
Thanks for drawing my attention to this record. Yes, it is Leucostoma persoonii. Its anamorph, Cytospora leucostoma, from otuside looks quite similar but with a single ostiole (rarely with two). The anamorph normally can be found in a separate stroma (unlike in L. cinctum where both stages usually develop in the same stroma, as you may remember we have already discussed here). A third species quite common on Prunus s.l. (incl. Cerasus & Padus), L. auerswaldii, differs from L. persoonii by larger spores and stroma configuration.
As far as I know there is no recently published key for all species of Leucostoma. Although it might be one day........ However, for example for Leucostoma species reported from Bulgaria there is a key in the monograph of Dimitar Stoykov 'Diaporthales of Bulgaria' (2012).

Vera
