Xylaria globosa, a " red" Xylaria..?
Esquivel-Rios Eduardo, 14-10-2012 21:34


 A Xylaria globosa (Spreng. ex Fr.) Mont. is a only Xylaria species with red-orange colorations in the ascostroma. This specimen found in the Cordillera Central, 500 mts. altitude, has these characteristics. The orange-red coloration develops only in thin sterile cilindrical stromata arising between fertile globose black stromata , they have few peritecias. The ascospores are 18-24 x 6-8 microns.
In http://mushroaming.com/Amazing_Amazon  is referred as X. glabrosa, but i cant found any references to this specie.

¿Xylaria schweinitzii Berk. & M.A. Curtis?

Re : Xylaria globosa, a " red" Xylaria..?
Gracias. La  X. schweinitzii reportada en Panama es totalmente esferica y no se mencionan la coloracion roja de estas estructuras, ver: http://www.flickr.com/photos/myxomop/5416371742/

Re : Xylaria globosa, a " red" Xylaria..?
En mi xperiencia, las especies del complejo Xylaria polymorfa (X. polymorpha, X. curta, X. complanata, X. Schweinitzii, X. scruposa, etc), presentag gutulas de colores vivos (rojos o amarillos) solo en el estado de anamorfo, cuando maduran ya no exudan gotas coloreadas. Por cierto, no se trata de un pigmento estromatal, si así fuera éste persistiría en el ectostroma de los ejemplares maduros, se trata de exudados acuosos coloreados mientras anamorfo.
Saludo.

Re : Xylaria globosa, a " red" Xylaria..?
hello

In my experience X. polymorpha s.st. and  X. obovata (syn schweinitzii) never produce red droplets when emerging but my concept of X. globosa does (= anisopleura). But this complex still needs a lot of attention using other methods :-)
The red drop producing taxon is extremely common in Ecuador and presumably over most of the Neotropics

cheers
