Re : Fungus with hair.
Spores and habitus looks very much like Leptosphearia (Pleospora) calvescens as depicted in Björn Wergen's new book (# 783).  Characteristic longitudinal septum in the broad end subterminal cell.  Is it growing on a herbaceous root?  Monocotyledon?  Not my specialty, though - just a suggestion.
