描述：

Habitat: : mountain scree slope, southeast aspect; open, sunny, dry place; calcareous ground; exposed to direct rain; elevation 680 m; average temperature 6-8 deg C, average precipitations ~3.000 mm/year; alpine phytogeographical region.Substratum: dead, rotten trunk of Fagus sylvatica lying on ground.Comments: This ascomycete remains a secret for me. It appears to have perithecioid ascomata with occasionally papillate apex, cellular pseudoparaphyses, bitunicate (hope so) and clavate/cylindrical 8-spore asci, ascospores with pigmentation and several septa and peridium composed of a few layers of cells. Thus it possibly belongs to fungi order Pleosporales Luttr. ex M.E. Barr. This order comprises tens of families and thousands of species. I searched for species, which stain decaying wood reddish/purplish. I browsed through short descriptions of about 160 species studied in the paper of Zhang et al. (2009) (Table:1). Several species, which stain substratum reddish, are cited, but none fits to this observation. It is also possible that my assumption about Pleosporales is completely wrong and this find is something totally different. Hard to manage is also the fact that the traditional taxonomy based exclusively on morphology has been overturned drastically by recent molecular studies. Hense proper naming of species (even genera and families) is confusing for an amateur. Unfortunately, there was no response from AscoFrance forum either. Any help would be much appreciated.Spores smooth, septated; from 3 to 7 septa, AVG = 4.5, SD = 0.9, N = 80.
