Indeterminate Podospora on rabbit dung
Francisco Calaça, 05-09-2014 03:19
Francisco CalaçaHi to all,
I found this Podospora (may be?) obtained of rabbit dung on dry forest (in Brazilian Savanna). I think can be a Podospora specie, but not a P. curvicolla or P. araneosa for me. I not have idea. Someone can help me, please? Maybe a new? Maybe a P. cochleariformes? Thanks for help!

The description of examined material:

Perithecia (dark) scattered, emerged to semi-immersed covered with flexuous, light brown, septate hairs. Peridium membranaceous opaque. Measure: 600-900 µm. Asci: broadly clavate, with ? 256 ascospores (?). Spores: at first one-celled, hyaline, after elliptical to oval, olivaceous to brown, with a pedicel cylindrical, collapsing. (9,6-) 11,7 (-13) × (6,5-) 7,3 (-8,4)µm. The ascospores have a De Bary Bubble. On rabbit dung. After two days on moist chamber.

With my best regards.

FJS Calaça.

Re : Indeterminate Podospora on rabbit dung
Hello Francisco.

Podospora cochleariformis possède des asques avec seulement 128 spores, et la taille des spores est plus grande.
Il faudrait que tu puisse observer s'il y a des appendices gélatineux et où se trouve le pore germinatif. Peux tu aussi mesurer le pédicelle, et faire des photos plus précises des spores ?

Amitiés.

Michel.
