Pinkish Orbilia on Eucalyptus inner bark

Hi to the Orbilia lovers


This nice species was found on the inner bark of Eucalyptus camaldulensis lying on the ground at the SW Spain, exactly at the place named Cuestas de Torreseca, Jarandilla de la Vera (Cáceres) Spain, 40º 03'48.59" N; 5º 35'22.22" O, 363 m. The sessile ascomata 0.4-0.9 mm in diameter have conspicuous glassy processes and the short 8-spored asci have the four lower spores reversed.


I feel it is close to albidorosea buy I'd like to know your opinion


Thanks in advance

I know this place from Phaeohelotium succineoguttulatum.

Yes, this Orbilia fits well the other samples of this species from Spain, in my opinion.

Can you tell me the date and collector, also the herbarium number? If you wish you can send me the plates by mail. It is funny that this species is so far found in Spain on Australian substrate only. In Australia we had it on Acacia, Jacksonia and Eucalyptus.

Was it a log or branch? On the moist ground or exposed? Detached bark?

Thanks!

Re : Pinkish Orbilia on Eucalyptus inner bark

Hi Zotto


The ascomata were found by me on dettached pieces of bark lying on the ground in a relative moist place. The date was february 28 and the material is keeped in my herbarium under ERD-6658. I'll send you my pics.


This fungus grew together with another still not studied orange species. Among the ascomata there were tri-arms conidia that perhaps belong to any of the two fungi... 


Thanks a lot

Re : Pinkish Orbilia on Eucalyptus inner bark
Interesting! Australian O. albidorosea has no tri-armed conidia but Dwayaangam (4 arms, 2 pointing downwards)., so either Spanish samples are a different species or the Trinacrium belongs elsewhere. Can you show me photos of the conidia?

Please keep me informed about the orange fungus.

Re : Pinkish Orbilia on Eucalyptus inner bark

Hi Zotto


As I said you yesterday, among the ascomata of albidorosea grew few others of an orange Orbilia not well preserved that I could no to study. No free ascospores I have seen. Only a few ovoid ones inside the asci. Their paraphyses are inflated and with a gel cap. But nonetheless I feel you can to identify this other Orbilia.


The showed three-arms conidia are somewhat under this other orange Orbilia rather than  albidorosea.

Re : Pinkish Orbilia on Eucalyptus inner bark
This Trinacrium is very probably the anamorph of Hyalorbilia erythrostigma which uses to parasitize on Orbilia spp.

The orange Orbilia is not easy. The spores look mature because their SB is very long and uncinate, and theiy measure 5-6 x 2.3-2.5 from the scale. This is a bit too narrow for O. gambelii but I have hardly another suggestion. Goog would be to see whether SCBs are in the excipular cells, and to see some paraphyses.

I'll try it, but ii will be not easy


Thanks!
