Hymenopleella sollmannii n. nom. (≡Sphaeria hippophaës Sollmann non Hymenopleella hippophaës (Fabre) Munk) was found to have unitunicate asci with a pulvillus, and a ring that turns blue in iodine. Isolates made from the triseptate, terete, brown ascospores produced pycnidia with annellophores bearing usually four-septate conidia with three brown cells and hyaline end cells each furnished with one short central seta. A comparison with Lepteutypa fuckelii (Nitschke) Petrak revealed that it is readily distinguished by the ascospores, which are narrower, octagonal in section, and furnished with a granular deposit in the middle line of the septa.
