Asco on fox dung
Enrique Rubio, 13-04-2016 19:29

Hi to all


This fungus grew on a culture of fox dung with many rests of animal hairs, and forms small, gregarious, superficial, roundish, yellowish at first, later orange and finally brownish cleistothecioid, smooth, ascomata, growing under a very copious white hypal mat.


The asci are small, roundish to ovoid, and the ascospores are smooth, yellowish, roundish or very broadly ellipsoid, 4.5-5.2 x 3.8-5.2 microns. Cleistothecial walls built by a yellowish textura angularis.


I feel this fungus belongs to Onygenales and it could be near to Aphanoascus fulvescens, a  keratinophilic fungus, but J. Guarro suggest me another possibility: Xanthothecium peruvianum. So I'd like to know your opinion


Many thanks in advance

Re : Asco on fox dung
Bonsoir Enrique.

Les spores de A. fulvescens ne sont elles pas normalement réticulées, ornées ?

Désole de ne pouvoir t'aider davantage.

Michel.

Bonsoir Michel


Les espores de fulvescens sont, selon la litterature, lisses, piquetées ou encore reticulées!


Surprenant!


Merci, Michel
