Hypocrea en Quercus suber
Javier Ormad, 27-10-2015 18:51
Javier OrmadHola. 
Hypocrea sobre restos de Quercus suber. Hasta 4 mm de ø.
Ascosporas esféricas y algunas oblongas y alguna con septo, ornamentadas con verrugas, verdes.
Excípulo con células globosas, subglobosas y angulares, y también una zona que en su parte externa presenta formaciones pilosas segmentadas.
Pienso en Hypocrea gelatinosa, pero esta última estructura que no se si esta presente, me hace pensar en H. strictipilosa......
¿Que os parece?
Saludos
Javier

Re : Hypocrea en Quercus suber
Hypocrea strictipilosa is the most common of several Hypocrea (now Trichoderma) species usually identified as Hypocrea gelatinosa. Without either DNA or culturing and observing these species at all stages of growth, positive identification is exceptionally difficult.

Hi Javier,


macroscopically, this does not look to me like H. strictipilosa (agg.), but more like H. aureoviridis.

Yes, typical Trichoderma aureoviride, not uncommon in western Europe.

Re : Hypocrea en Quercus suber

Hi Hermann, I am happy about your confirmation! I found the species in the Algarve, but also in Germany. Finding places are in my experience mostly lowland floodplain forests in thermophilous habitats, on hardwood

Re : Hypocrea en Quercus suber

Yes, T. aureoviride is found in damp forests in areas with mild winters (Western and Southern Europe), on wood of various trees and shrubs. In suitable habitats it appears to be common e.g. in England and The Netherlands.
