: Hallo zusammen

: Hier noch ein Nachtrag: Wie ich inzwischen herausgefunden habe ist die
: Konidienform von Ascocoryne sarcoides unter Coryne dubia bekannt. Leider
: reicht meine Literatur nicht aus weitere Informationen über die
: mikroskopischen Merkmale von Coryne dubia zu erhalten.

Hallo René,

Dein Pilz dürfte aufgrund der Größe sicher Coryne dubia sein, die NFF von Ascocoryne sarcoides. H.O. Baral kennt noch eine weitere, ähnliche Art (noch unbeschrieben),die sich durch ein deutlich kleineres Konidienstadium auszeichnet. Und zuletzt gibt es noch die blaß fleischbräunliche, winzige Ascocoryne solitaria, die ein einzeln wachsendes, blaßviolettes Konidienstadium hat (Coryne albida).

Hier mal die beiden Beschreibungen von Ascocoryne sarcoides und A. "disciformis", nach H.O. Baral (Quelle: CD "In vivo veritas", der Fettdruck der NFF-Beschreibung stammt von mir):

3. Ascospores with quite constantly ±tapered ends, *(14-) 17-27 (-28.5) x 4.4-6 µm, slightly to medium curved, homopolar, large LBs 2.8-4.5 µm, conidia of germ tubes *3.2-3.6 µm wide; asci IKI 3BB, paraphyses mostly very strongly capitate, upper cell *6-27 x (3-) 4-7 µm, ±without contents, apothecia 3-10 mm diam., sessile, 1-5 mm thick, lentiform-cushion-shaped, margin ±appressed to substrate, deep purplish, sometimes associated by small conidiomata (0.5-1 mm high, irregularly cerebriform, pale rosaceous-purpuraceous, non-gelatinous) growing in separate populations (phialides *10-15/1.8 µm, conidia *4-4.5 x 1 µm, medium allantoid); on very rotten wood or bark of branches of Fraxinus, Fagus, Alnus, shady woods, creeks or Alneta .. A. disciformis sp. nov.
HB 3121, 6772, 6788a, 6810, 6838

3. Ascospores with constantly ±rounded ends, *11-23 (-27) x 3.8-5.5 µm, partly heteropolar, two large LBs (2-) 2.5-3.5 (-4) µm diam., conidia of germ tubes *1.8-2.8 µm wide; asci IKI RB/BB; paraphyses slightly to medium inflated; apothecia 3-22 mm diam., on a ±conspicuous stalk, c. 4-10 mm high, obconical-turbinate, stipe often distinct, not rarely higher than wide, margin not appressed to substrate, always associated with conidiomata (Coryne dubia, these occur mostly in much higher number than apothecia): stipitate, clavate to flabelliform conidiomata, without delimited head, c. 2.5-15 x 1-5 (-15) mm, often fasciculate, deep purplish-violet, phialides *9-15 (-20) x 1.3-1.5 µm, conidia *(2.8-) 3.3-5.5 x 1-1.4 µm, slightly (to medium) allantoid, 1 minute LB (or 0.6-0.8 µm) near each end, some with small polar appendage so that conidia at first loosely cohere in chains; on wood or often on bark of branches, stems and stumps of Fagus, Quercus, Alnus, Prunus, Carpinus, Castanea, Acer, Pinus, Larix (never on Picea?), often undecayed or only slightly rotten (rarely ??strongly rotten), in creeks or shady woods, ?slightly xerotolerant .. A. sarcoides
