Ostropales indet. 2

Hans-Otto BaralHere is the second one. This has an inamyloid hymenium (like Ostropa and Robergea), but the spore sheath is very distinctly hemiamyloid!

N of Digne, Quercus pubescens branch 10 mm thick. Sp. ca. 300 µm long, *2.5-3.2 µm wide, cells 8-8 µm long, lipid content 1.5-2.5. Asci and whole hymenium inamyloid, but spores in dead state (sometimes also living?) IKI 2rr, after shortly boiling IKI bright blue.

The ascomata are almost perithecioid here.

Re:Ostropales indet. 2
Hi Zotto,

could it be Schizoxylon albo-atrum? At least this is my outcome with the key of Schizoxylon by Martha Sherwood.

Best wishes,

Gernot

Re:Ostropales indet. 2
Hi Gernot

thanks, that's a good idea! Sherwoods illustration on p. 112 fits quite well. The ascospore cells she gave as 4-5 x 2 µm, while I measured 5-8 x 2.5-3.2 µm in the living state (sorry for my error above). It is a pity that we do not know whether the spores are also hemiamyloid in Sherwood's material, especially Rehm's type. Sherwood says for the paraphyses J- or faintly J+ blue, but we must know that she used Melzer, and a hemiamyloid hymenium like in my Ostropales indet. 1 would be in Melzer just like that, J- or faintly blue. In one of her material of alboatrum (from Oregon) she reported a strongly amyloid epithecium. And I do not understand why she says "apparently common" but cites only 7 collections.
