Neofusicoccum umdonicola is morphologically similar to other related species in the N. parvum/N. ribis species complex. Conidia of N. umdonicola are hyaline, unicellular, fusiform to oval, apices tapered (Pavlic et al., 2009).
N. umdonicola differs from other species in the N. parvum/N. ribis complex by uniquely fixed nucleotides in four nuclear loci: internal transcribed spacer rDNA (ITS1, 5.8S and ITS2), translation elongation factor (1-a), btubulin-2, RNA polymerase II subunit.

The species was firstly collected in South Africa in 2008, country with the highest number of occurrences, but there is still little data on its ecology. In Brazil, the area of ​​occurrence is the Atlantic Forest, one of the main global biodiversity hotspots, threatened by urbanization. I suggest inclusion of it in the near threatened category.

The species is known in two countries, but GBIF shows only one. South Africa has 5 occurrences, while in Brazil it is known in one of the 26 states.

There are about 6 records of the species in the world, of which five (84%) are in South Africa.  Brazil has one occurrence of Neofusicoccum umdonicola, in the states of Alagoas (unpublished).

The species is found mainly in South Africa, presenting only one record (as endophyte) in Brazil.

The one occurrence of the species in Brazil were in the Atlantic Forest, one of the largest biodiversity hotspot on the planet.

In Brazil it occurs in an area of ​​environmental protection, but it is also found in agricultural areas in South Africa.

Studies of other biomes will contribute to assessing the species distribution.
It is part of the Neofusicoccum parvum-Neofusicoccum ribis species complex, and molecular studies need to be used to assist in species recognition, providing knowledge about the diversity in Botryosphaeriaceae.

So far there are no studies on the use or trade of the species.
