Abstract
During survey for the foliicolous fungi from diversified habitats of Tilkoma Forest, Gorakhpur U.P. India, we came across an important plant of the locality, Eugenia heyneana (Family-Myrtaceae) commonly known as Kath Jamun is a large shrub or small tree, up to 6 m tall, with branchlets obscurely four-edged. Leaves are simple, opposite, estipulate; leaf-stalk 4-5 mm long, slender, grooved above, hairless; blade 6-10 x 1.3-3 cm, oblong or elliptic, base narrow, tip blunt or flat, margin entire, leathery, hairless, pale beneath, glandular dotted; lateral nerves many parallel, close, but slightly irregular, very slender, slightly prominent on both sides, looped at the margin forming intramarginal nerve, intercostal net veined, slender prominent as lateral nerves. Flowers are bisexual, small, stalk less, white, in lateral, at branch-ends or rarely in leaf-axils cymes; sepal-cup tube 2 x 3.5 mm, top-shaped, no thick disc; petals calyptrate, 3 mm across; stamens many, free, bent inwards at the middle when in bud; filaments 3 mm long; ovary 2-celled; ovules many; style 1; stigma simple. Fruit is a berry, obovoid, 1-1.5 x 0.5-0.7 cm, crowned with the cup-like sepal-cup limb. Kath Jamun is native to India. On critical study the living leaves were found to be infected with Pseudocercospora. Since it has also been customary for plant pathologists and mycologists to describe as new any Cercospora or Pseudocercospora found a host for the first time (Ellis, 1971), this undescribed taxa has been described and illustrated as Pseudocercospora eugeniae-heyneana e sp. nov. Rajiv Ranjan. The review of available literatures reveals that there has been no record of this fungus from India on this host so for. Therefore, this host of the new species is a new record to Indian mycoflora from Tilkoma Forest, Gorakhpur U.P. India.
