Description:

Colonies epiphyllous on Merremia sp. Superficial mycelium absence and appear as blackened areas on the leaf surface. Sexual morph: Thyriothecia up to 150 μm in diam., superficial, confluent to scattered, with circular to irregular, covering membrane dark brown to black composed with cells. Hamathecium composed of filiform, sub hyaline, pseudoparaphyses. Asci 15–20 × 12–15.5 μm (x̄ = 17.5×13.5 μm, n = 10), 8 spored, hyaline, bitunicate, globose or subglobose, obovoid to clavate, short pedicellate or without pedicel. Ascospores 10–15 × 5–7 μm (x̄ = 12.5 × 6 μm, n = 10), ellipsoid to fusiform, usually two-celled, normally unequal, obviously constricted at septa, upper cell wider, lower cell narrow and longer, hyaline, then turning to brown when spores are mature, wall smooth. Asexual morph: Unknown.

Material examined: Philippines, Laguna Province, on dead leaves of Merremia sp. (Convolvulaceae), October 1913, Baker, Charles Fuller (CUP-F-F.Mal.0333, isotype).

Importance and distribution

Ferrarisia comprises eight species. Ferrarisia philippina is synonymized under F. ipomoeae. Ferrarisia jasmina is synonymized and transferred to Palawaniella. Ferrarisia is distributed on Capparis sepiaria (Capparaceae), Eugenia sp. (Myrtaceae), Ipomoea obscura (Convolvulaceae), Jasminum angulare (Oleaceae), Litsea glabrata (Lauraceae), living leaves of Persea (Lauraceae), Quercus glauca subsp. annulata (Fagaceae), Smilax macrophylla (Smilacaceae) and Ziziphus rugosa (Rhamnaceae). Ferrarisia is reported from Asia (India, Myanmar, Philippines), Central America (Costa Rica), South Africa and South America (Brazil).
