Je to sice z jarabiny a na prvy pohlad bez lupy to moze vyzerat ako jasna zalezitost.
Ale ak si pozriete "makroskopicky" plodnicku tak vidite na vrchole bradaviek akoby depresiu /taky ciaskovity tvar/ a nie ziadne rozpuknutie. Zaroven neviem nikde najst ake by mala mat Eutypella sorbi vlastne velke mikro znaky. Mozem sa odrazat len z fotografii na internete ale tie su kupodivu vlastne bud z nahuby alebo fotonetu takze som zatial s toho dost zmateny .
Vie mi niekto nejako zrozumitelne vysvetlit hlavne rozlisovacie znaky rodov Eutypella a Diatrypella ?

stróma 2-5 mm široká, 2-3 mm vysoká, sediaca pod kôrou, ktorú preráža. Farba čierna. Ostiolá s 3-5 hlbokými ryhami, hranaté a výtrusy 7-11 x 1,5-2,5 µm
mierne prehnuté.
S tvojími výtrusmi nesedí. Skúsim sa ešte pozrieť.

Čo sa mi podarilo zistiť:
Diatrypella - vrecká valcovité, mnohovýtrusné, strómy oddelené od substrátu dookola čiernou zónou
Eutypella - vrecká kyjakovité, 8-výtrusné, strómy oddelené od substrátu zvyčajne len v spodnej časti

Allantosporous genera:
Cryptosphaeria
Stromata widely effuse within bark tissues that are slightly elevated, usually unchanged, but sometimes discoloured or darkened, with separate, rounded or stellate ostioles at the surface. Asci clavate or cylindrical, 8-spored, usually with long stalks, paraphysate. Ascospores allantoid, hyaline or brownish.
Cryptovalsa
Stromata rather variable, eutypoid, but when erumpent separately
diatrypelloid, often immersed in wood but sometimes invading bark tissues.Asci cylindrical or clavate, polysporous, with short or long sralks. Ascosporescrowded, allantoid, yellowish.
Diatrype
Stromata widely effuse or verrucose, flat or slightly convex, with discoid or sulcate ostioles at the surface. Perithecia mostly in one layer, but sometimes polystichous. Asci clavate, 8-spored, usually with long stalks, paraphysate.Ascospores allantoid, hyaline or brownish.
Diatrypella
Stromata conical-truncate, cushion-like or discoid, usually delimited by a black zone in host tissues, with umbilicate or sulcate ostioles. Asci cylindrical.polysporous, with long stalks. Ascospores allantoid, hyaline or yellowish.
Eutypa
Stromata widely effuse within wood tissue causing its blackening, with separate, rounded or sulcate ostioles at the surface. Asci clavate or cylindrical, 8-spored, usually with long stalks, paraphysate. Ascospores allantoid, hyaline or yellowish.
Eutypella
Stromata erumpent from bark as crowded perithecial beaks, mostly sulcate, sometimes rounded, usually without ectostromatic disc but united below by a common tissue that sometimes strongly developed and causing the appearance of pulvinate prickly globules. Asci clavate, 8-spored, with long stalks. Ascospores allantoid, hyaline or yellowish.
