bonjour j'ai trouvé la semaine dernière a Mayotte des hypocrea sur rosellinia cf corticium
J'ai vu dans "european species od hypocrea part II species with hyaline ascospores" qu'il existe HYpocrea stilbohypoxyli venant sur rosellinia corticium (holotypr puerto rico)
Existe t'il d'autres espèces d'hypocrea venant sur le même support ???
Voici la description de mes spécimens Carpophore :
d'abord en forme de demi sphère de 1 à 32 mm de couleur jaunâtre piquetées de point noirs (ostioles ???) poussant sur les stromas ou le subiculum de rosellinia corticium, isolés ou agglomérés, en vieillissant sous forme variable circulaire ou irrégulièrement lobé
Spores hyalines rondes verruqueuses 3.7 – 4.2 – 4.7 – 5.1
Asques 16 spores rondes verruqueuses ; à l'origine 8 chacune se scindant en deux 73 – 85 x 4,8 aps de paraphyses
?
I have seen a similar thing several times, but it did not grow, therefore I did not describe it. Perhaps it grows from your specimen. So, if you wish, send it to me.

I received Maurice's specimen three days ago, it is in culture and the ascospores germinated.
If you need of this culture, I can send you two plates (and the specimen) as soon as possible.
Regards,
Christian
I sent the specimen now they come within a fortnight
cordially
thanks for the nice material and cultures. The Hypocrea is H. jecorina, also known as Trichoderma reesei. This is a common tropical species, but as the Longibrachiatum clade now contains 21 species, sequencing is required, which in this case clearly supports its identity.
Cheers,
Walter
Thank you very much.

Christian
