Hello! I found this species that resembles Delitsc
Hello everyone,Collected on a decorticated branch of Quercus robur here in Belgium:
Ascomata superficial to slightly immersed, subglobose, 0,1-0,15 mm diam., papillate, pale brown, covered by black setae. Asci cylindrical, apex truncate, 8-spored but mostly observed with 16 part-spores, 42-47x6 µm. Spores fusiform, constricted 1-septate, soon disarticulating in part-spores; part-spores ellipsoid to wedge-shaped, smooth, hyaline, 3-3,5x1,5-2 µm. Paraphyses soon disappearing. Ectal excipulum of pale brown, small-celled textura ?epidermoidea; setae acute, base swollen, smooth, thin-walled, aseptate, blackish, 39-56x7-10 µm.
With those Hypocrea-like spores, this must be a Melanopsammella? Unfortunately, I only have documentation of species with septate hairs.
Your help is welcome.
Bernard
this reminds me strongly of Trichosphaerella decipiens, with apically acute, mainly unbranched setae. But what I know under that name (on Peniophora) has globose, finely warted spores.
But Ellis & Ellis (pl. 1193 in centre of plate) figure elongate spores.
Similar is Neorehmia ceratophora, with antler-like setae and also globose warted spores.

Hi to everybody
This collection of a Trichosphaerella/Melanopsamella species on decorticated wood of Sambucus nigra seems to be very close with Bernard's collection on Quercus.
Has someone more suggestions about it?
Thanks again
I fear that nobody will see your posting except me and Bernard?
Has someone this article? Samuels & M.E. Barr (1998) Notes on and additions to the Niessliaceae (Hypocreales): Can. J. Bot. 75(12): 2166 ['1997']
Maybe it could help us...
Le voilà.
Amitiés, Guy
