“…The genus Mycosphaerella and Mycodidymella belong to Loculoascomycetes, Dothideales, Mycosphaerellaceae. Funk and Dorworth (1988) and Wei et al (1998), however, did not mention that M. alni, the type species of Mycopappus, to be a sclerotiniaceous fungus. On the other hand, Mycopappus quercus developed a teleomorph belonging to Sclerotiniaceae, as suggested by Redhead and White (1985) in M. alni.…”

“…(Wei et al 1998), respectively. These fungi produced true conidia on spots on leaves, as well as on sporodochia (multicellular propagules) in M. aesculi (Wei et al 1998). The quercus are long and densely fasciculate to form a conical erect structure, although the appendages sometimes flared loosely in wet conditions.…”

“…Mycelia of M. mycopappi on malt agar develop a dark blackish-green center, a broad hyaline border, with a sparse aerial hyphae, but no sporulation was observed (Funk 1987). Colonies of M. aesuculi on potato sucrose agar are raised, circular, white, with abundant aerial hyphae, and produce sporodochia, conidia (on the sporodochia), and spermogonia (Wei et al 1998).…”

Redheadia quercus gen. et sp. nov., the teleomorph of Mycopappus quercus, the frosty mildew fungus in Quercus acutissima Abstract The teleomorph of Mycopappus quercus causing frosty mildew in Quercus acutissima is described as a new genus and species, Redheadia quercus, in the Sclerotiniaceae. Apothecia sprout from sclerotia on the fallen infected leaves kept for 10 months at 5°C and subsequent incubation at 15°C under diffused room light. Typical zonate lesions and multicellular propagules of M. quercus are produced on Q. acutissima, by mycelial inoculation using an isolate from a single ascospore, confirming the teleomorph-anamorphic connection. No significant differences are observed between cultured colonies of isolates from the ascospore and those from the propagule. Sclerotia and microconidia of the fungus are produced on culture media.

The causal fungus of frosty mildew in Quercus acutissima was taxonomically studied. Brown spots with conical white to yellowish tufts of the causal fungus developed on the leaves, followed by successive defoliation. The fungus was regarded as a new species of Mycopappus, M. quercus, from the morphology of the multicellular propagules. The ascogenous stage and true conidia of the fungus were not observed, although sclerotia were formed on the fallen diseased leaves.

A leaf disease similar to frosty mildew disease caused by Mycopappus species was detected on the leaves of Crataegus chlorosarca in Tomakomai, Hokkaido Prefecture. From morphological observations and gene analyses of rDNA-ITS, the fungus was identified as M. alni, which causes leaf blight disease on Alnus spp., Betula spp., and a Pyrus sp. in North America and Turkey. This is the first report of M. alni in Japan and Crataegus as its new host genus.
