Diatrype acericola De Not., Sfer. Ital. View in CoL : 28. 1863 ( Fig. 6 View FIGURES )

Specimens examined:— CHINA. Jilin Province: vicinity of The Red Leaves Valley of Jiaohe, Shasongling area , on dead branches of Acer mandshuricum Maxim. , 30 August 2013, L. Vasilyeva, VLA P-2806 .

Stromata erumpent from bark with a circular or elliptic, brownish or almost black ectostromatic disc 1–2 × 1–1.5 mm, surrounded by a black line within the substrate; perithecia monostichous or distichous, singly erumpent, 200–250 µm diam., with short and stellate at the top ostiolar necks. Asci cylindrical, paraphysate, 23–27 × 5–7 µm in spore bearing part, stalks of different length, containing 8 biseriate or conglobate ascospores, apical ring indistinguishable. Ascospores one-celled, allantoid, very slightly yellowish, 7.5–9 × 0.9–1.1 µm.

The name of this species was given as a synonym of Eutypella leprosa (Pers.) Berl. ( Rappaz 1987) and is considered now as a basionym of Eutypella acericola (De Not.) Berl. (http://www.speciesfungorum.org), but the stromata do not correspond to the concept of Eutypella because of separately erumpent ostioles and the arrangement of perithecia in one layer near the stromatal surface ( Fig. 6 View FIGURES ). The species is very common in the south of the Russian Far East ( Vasilyeva 1998), but there are no reliable records from North America so far. Although Acer is indicated as the substrate for Eutypella leptosa from eastern Unites States of America ( Farr et al. 1989) and this might suggest Eutypella acericola , we never encounter this species while collecting specimens in eastern states of that country (e.g. Maryland, Michigan, New York, North Carolina, Tennessee, Virginia).
