K&J REMARKS Salmon (1903, p. 128-129) studied a type-slide loaned from Pampaloni, and redescribed Uncinulites. Salmon, a specialist in the study of the Erysiphaceae, stated that he cannot suggest a natural affinity for these forms, but that they bear no resemblance to any of the species of the genus Uncinula of the Erysiphaceae. [Jansonius & Hills (1979), card no. 3621.]

Graamspora Salard-cheboldaeff & Locquin 1980 is similar to Uncinulites in having spinose or echinate spores, but in Uncinulites the spores are spherical whereas in Graamspora they are oval to elongate in outline (Elsik, 1992). In Kalgutkar and Jansonius's (2000) opinion, differentiation based only on shapes of the spores is generally confusing and arguable, as shape and outline of spores by themselves are not good characters to separate one species from another. Living spores with variable shapes can be found on the same mycelium, possibly representing different stages of development. Yet, these can be easily recognized to belong to the same species, even in a dispersed state, if they acquire even a single constant diagnostic feature. Spores in both Graamspora and Uncinulites are unicellular, aporate and typically spinose. The presence of spines on the spore walls is a consistent morphological character that makes them similar enough to group them in the same genus. Kalgutkar and Jansonius (2000) transferred Graamspora to Uncinulites.
