[1] Heterotruncatella was introduced by Liu et al. (2019a),[1] to accommodate several new and previously described Truncatella Steyaert species (also within the family Sporocadaceae).
[4] In 2020, black spot needle blight was found on hundreds of Pinus sylvestris var.
As the fungal disease progressed, the needles eventually died and turned gray with many dark black spots.
The fungus was identified as Heterotruncatella spartii based on morphology and molecular methods.
[5] It has a scattered distribution, found in parts of South America, Europe, southern Africa, China,[5] and Australia.
