A filiform Xylaria ?

Hi All

May the Xylaria experts can help in this fungi found growing in a dead twig in the soil. The filaments reach 30 cm. long, 0.5 - 1.0 mm. wide, black, smooth, coriaceous, hollow with a soft tissue inside. No found peritecias o any kind of spores.

Re : A filiform Xylaria ?

Hi Eduardo,
I think that your specimens are rhizomorphs of Polyporus. These can be several meters long.

Re : A filiform Xylaria ?

Bonjour à tous,
voici ma récolte de Polyporus rhizomorphus décrit par Montagne qui est abondant en Guyane. Mais on trouve très rarement les basidiomes ; suivant l'article SMF (joint) ces filaments sont des télépodes et sont souvent improprement nommés "rhizomorphes", il s'agirait en fait des prolongement des stipes !
