Nemania sp. JF-02150
Stroma superficial, narrowly ellipsoid, 6 mm long x 2.5 mm broad x
0.6-0.7 mm thick, weakly carbonaceous; surface blackish brown, plane, squamulose,
finely
reticulate; whitish soft tissue present beneath the perithecial layer, inconspicuous.
Perithecia subglobose, 0.5-0.6 mm diam x 0.5-0.7 mm high.
Ostioles
minutely papillate, black.
Asci cylindrical, long-stipitate, the spore-bearing parts 65-75 µm
long x 7-10 µm broad, the stipes averaging 60 µm long, with apical apparatus
cylindrical to urn-shaped, amyloid, 3-3.5 µm high x 2-2.8 µm broad.
Ascospores
10-12.5 x 4-4.8 µm, pale brown, ellipsoid-inequilateral with broadly rounded
ends, with a short, inconspicuous germ slit 3.5-4 µm long on the less
convex side.
Specimen examined: FRANCE: Ariège (09): Vernajoul, Pont
Fagé, ruisseau de Vernajoul, 31 Aug. 2002, JF-02150, on bark of a little branch
of Quercus sp.
Notes: This fungus is likely to be a Nemania, basing on stromatal
morphology and microscopic characters, and agrees quite well with N. serpens
var. colliculosa except in the squamulose and finely reticulate stromatal
surface, and in slightly larger perithecia. The specimen consists of only
one small stroma and additional material is needed so that its differential
characters can be evaluated.
