Rosellinia evansii Laessøe Spooner, Kew Bull. 49(1): 35. 1994.

 Description: Stromata carbonaceous, crust-like, 128-269 μm thick, immersed or with the upper part erumpent through the bark, covering 1 or rarely 3 ascomata except the base of ascoma. Ascomata beneath stromata, conoid, 706-719 μm wide, 600-674 μm high, with an flattened base, apex piercing the stroma, non-periphysate. Peridium 32-38.5 μm thick, composed of pale brown, strong compressed, areolate cells seen as angular patches on surface view. Asci cylindrical, 269-333 × 12-16 μm, unitunicate, stipitate, stalk 70-141 μm long, basal, 8-spored, with an amyloid, barrel-shaped, 6.3-5.5 μm apical ring. Ascospores elliptical, 25-34 × 12-16 μm, uniseriate, with a 1-2 coiled helical germ slit.

 Note: In this specimen stellate ruptures of host tissues observed by Laessøe & Spooner (1994) in their descriptions were not seen. The ascoma of this specimen tends to become erumpent through the substrate and is surrounded by the remnant of the substrate. This difference may be attributed to the different type of host.
