SPECIES, AUTHORITY R. oblongispora Caspary 1907, p. 15, pl. 1, figs. 11a,b.
LOCATION Baltic area, Poland.
ORIG DESCRIPTION* On the tip of a slender stylus surmounting a small fruit, grows a fungus that extrudes from the inner parts of the infected organ. It consists of nearly cylindrical threads (fig. 11) that are articulated and at their tips branch into 1-4 branches (fig. 11b), and that are nearly colorless except for a tinge of a brown hue. The cells in the hyphae are commonly somewhat convex, somewhat roller- or barrel-shaped. Near its apex, the hyphae branch and segregate ovoid or elliptical spores, a number of which became detached and fell around the hyphal base (e.g., at b in fig. 11). The fungus is 45.4-51.1 µm long and 1.8-4.2 µm wide; the fallen spores are 2.8 µm wide and twice or three times that in length.
COMMENTS* The genus Ramularia is understood in the sense of Saccardo: articulated, rarely simple, hyphal threads that rise up and shed elongate, unicellular or pluricellular spores. The [species] Ramularia didyma Ung., illustrated by Unger (Exanth. II, fig. 12) has been raised to its own generic level by Corda (Icon. V, p. 7-9), as the genus Didymaria.

To Ramularia also belong fungal hyphae on the anthers of a Castania, illustrated by Göppert (1845), and described (and illustrated) by Caspary (l.c., fig. 12).

K&J REMARKS The name Ramularia was published for an extant fungal genus by Unger (1833), without a designated type species or holotype; this name is a junior homonym of Ramularia Roussel 1806, given to a chlorophyceous alga (type: Ulva lactuca L.). Clements & Shear (1931) assigned Ramularia uricae Cesati as lectotype of Ramularia Unger; however, according to Farr et al. (1979), this species does not include either one of Unger's two specimens [and hence cannot be a lectotype]. Kendrick & Carmichael [1973, Hyphomycetes; In: Ainsworth et al., v. IVA, p. 323-509], when referring to Ramularia Unger 1833, cited R. didyma Unger as lectotype (Von Arx 1970), and placed it under didymosporous genera, as having 2-celled spores. Hawksworth et al. (1983), who prepared the seventh edition of the Dictionary of the Fungi (including Lichens) by Ainsworth & Bisby, also included Ramularia Unger 1833.

Saccardo (1880, p. 995), apparently unaware of the works of Roussel (1806) and Unger (1833), independently used the generic name Ramularia, without citing a type, for unicellular or pluricellular fungal spores. In contrast, Ramularia Unger is didymosporous.

Klebs in Caspary (1907) commented on the genus Ramularia, and stated that "The genus Ramularia is understood in the sense of Saccardo: articulated, rarely simple, hyphal threads that rise up and shed elongate, unicellular or pluricellular spores. The species Ramularia didyma Ung., illustrated by Unger (Exanth. II, fig. 12), has been raised to its own generic level by Corda (Icon. V, p. 7-9), as the genus Didymaria."
