? Lophiotrema with crimson interior in KOH
Alex Akulov,

Dear friendsCan you help me to identificate one Ascomycete fungus with very distinct macromorphology? I think it may be Lophiotrema sp., but have no idea what same. May be you already familiar with it.
Fructification formed on the rotten decorticated wood of foliage tree (cf. Quercus) in the maple-linden-oak forest).
Pseudothecia 315-430 µm in diam., black, solid, thick-walled, with bases immersed in the thin black stroma, which cover all substratum surface.
In the mature ascomata the upper part of pseudothecia splits and exposes the brown interior. In KOH ascomata interior distinctly stay crimson.
Asci bitinicate, av. 95 × 14,5 µm, wider at the top and gradually tapering to the stipe. Pseudoparaphyses abundant, branched, filiform. Ascospores mostly two-seriate, fusiform, slightly curved, with (3-) 5-7 transverse septae, with distinctly inflated submedian cell, (22-) 23,6-26,6 × 4,4-5,7 µm (in the broadest part). Ascospores at most hyaline, but some brownish were observed too.
Photos turned out not very successful, but allow you to see the main features.
Grateful before for help,
Alex

Hi Alex,
You may take a look in the Roussoellaceae if your species has crimson colored ostioles and spores with a +/- big gel sheet.
Cheers,
Guy
