Abstract

A new species of rust fungus, Maravalia perae on Pera sp. (Euphorbiaceae), from Brazil is proposed. Spermogonia are type 5 and aeciospores and urediniospores are asymetrically obovoid to ellipsoid, with a concave side and 3(-4) equatorial germ pores. Teliospore walls are 2-5 pm thick at apex around the apical germ pore. This set of characters differentiates M. perae from other species of Maravalia. A revised key to all known Maravalia species, including the newly discribed species, is provided.

摘要

本文提出了一种来自巴西、寄生于大戟科佩拉属植物上的锈菌新物种——佩拉马拉瓦锈菌。性孢子器为5型，锈孢子和夏孢子呈不对称倒卵形至椭圆形，有一个凹面和3（-4）个赤道生芽孔。冬孢子壁在顶端围绕顶端芽孔处厚2-5微米。这一系列特征将佩拉马拉瓦锈菌与马拉瓦锈菌属的其他物种区分开来。本文还提供了一份包括新描述物种在内的所有已知马拉瓦锈菌物种的修订检索表。
