Unknown species on hardwood
Ralph Vandiest, 08-04-2014 20:52
Ralph VandiestHello,

I found this species on unknown hardwoord. Frb 2/4mm x 1mm. At the inside you can see multiple round holes (diam 0,5x0,3mm).  Spores with 2 very small drops. Size 2/3x9/12µm.

Any suggestions?

regards,

Ralph

Re : Unknown species (conidial state) on hardwood
Por el tipo de esporas pensaría en un Colletotrichum... pero realmente debería de observar el tipo de estructura donde se desarrollan las esporas para mencionarte.

Hello,


I found some asci (+- 60x10µm). Also added some pics of the inner structure.

Re : Unknown species on hardwood
Te mencione Colletotrichum debido a que he visto este tipo de esporas en algunas plantas... pero definitivamente no lo es por el concepto de presencia de ascas.

Re : Unknown species on hardwood
Hi,

so we come back to Eutypa/Eutypella. This case is most probably a species of Eutypella due to its clustered perithecia embedded into a stroma.

Hi Ralph


The white endostroma suggest me Eutypella leprosa

Hello all,


Indeed, the white entostroma leads in my eutypella key also to E leprosa.
