Notes

Uleopeltis was introduced to accommodate U. manaosensis and later the second species U. bambusina added to this genus ( Hennings 1904, Dai et al. 2017). Uleopeltis manaosensis was synonymised under Mendogia , while U. bambusina remained in Uleopeltis which was collected from bamboo culms in he Philippines ( Hennings 1904, von Arx and Müller 1975, Dai et al. 2017). The species lacks molecular data and shares similar morphological characteristics with the type species of Mendogia ( von Arx and Müller 1975). Dai et al. (2017) gave spores of the type material of Mendogia bambusina as 13.5-25 × 5-8 µm, but mature ascospores in the photographs are 15-21 × 7-9 µm. Raciborski (1900) gave the ascospores as 17-19 × 8 µm for M. bambusina . This supports the assessment of von Arx and Müller (1975) that M. bambusina and Uleopeltis bambusina are conspecific. The synonymisation is formalised here. The report of M. bambusina from Brazil on palm leaves ( Vitória 2012) has been documented with morphological and anatomical photographs and agrees well with the material from the Paleotropics. The African Pleiostomella halleriae ( Doidge 1921) will also key out close to M. bambusina and may represent another synonym. It is the only other species described in Pleiostomella , a synonym of Mendogia , but has apparently never been dispositioned. Unfortunately, no type was indicated and a total of six collections on two host species (leaves of Halleria elliptica and H. lucida ) were listed. The ascus and ascospore dimensions (50-70 × 20-33 µm; 22-24 × 9-10 µm) partly fit M. bambusina , but Doidge described two types of asci, one ovate and ca. 50 × 30 µm and the other clavate and ca. 65-70 × 20-25 µm. The latter fits M. bambusina , whereas the former does not conform to any of the species recognised here. Revision of all paratypes is necessary to assess the taxonomic status of this material ( Sydow and Sydow 1917).
