Tofispora scaberula is a South American species. It has a relatively large distribution but is only known from only 3 collections made between 1978 and 1999.  Without further search attempts it is difficult to differentiate whether this species has a small population size and is potentially threatened or if it is overlooked and possibly Least Concern. Therefore it is assessed as Data Deficient (DD).

Originally described as Botryohypochnus scaberula and later transferred to Tofispora in 2007. In 1998, Peter Roberts transferred all known Tofispora species to Thanatephorus, and considered them to be synonymous. However, upon the establishment of Tofispora scaberula in 2007, Hjortstam and Ryvarden still applied the genus Tofispora for this group thereby leaving T. scaburela as the only remaining species in its genus.

Known from Colombia (Cunindamarcha) and Venezuela (Bolivar and Aragua). (Hjortstam and Ryvarden 2007)

T. scaburela is only known from collections made in 1978, 1995 and 1999 in 3 sites in Colombia and Venezuela. The small number of records could suggest a small population size but this may also be caused by a difficulty in identification or confusion with other similar species as well as under sampling, especially considering this is a resupinate fungus. Without further records it is therefore not possible to estimate population size.
Since this species is a saprotroph and found growing on hardwood and a dead polypore, it is difficult to establish population decline.

Resupinate species, found growing on hardwood and dead polypore.

Unknown.

Taxonomic research is recommended to review the placement of this species in the Tofispora genus. Targeted search efforts are also needed to establish population size, distribution limits and habitat preferences.
