Scorias

Scorias is a genus of fungi within the Capnodiaceae family.[1] The genus was first described by Elias Magnus Fries in 1832.[2] The fungus is known as sooty mould and is found growing on honeydew on leaves of many varieties of trees and plants.[3]

Characteristics

The mycelium of these fungi have parallel walls and form a thick spongy mass. The perithecium is round and long stalked and the spores have four cells.[4]

Effects of sooty mould

Sooty moulds grow in thin black layers on leaves on which aphids, witefly or other sap-sucking insects have deposited their honeydew. It does not grow parasitically but it harms plants indirectly and is also unsightly. The mould coats the leaves and this blocks out light and makes photosynthesis less effective. Plant growth can be reduced, leaves covered in mould may die prematurely and there may be a reduction in fruit yield.[3]

gollark: In JS you used to have to explicitly handle callbacks for all that stuff, and then used to have to have a lot of `.then` calls on promises, but now we have `async`/`await` so it looks basically like regular code.
gollark: One sort of nice but also sort of problematic thing about Go is that it uses green threads so operations like writing files look synchronous and you can write code accordingly, but are done asynchronously.
gollark: Strictly speaking it has generics, but hardcoded ones on arrays/channels/maps.
gollark: So you need `if err != nil { return err }` everywhere because it has no exceptions or stuff like `Option`.
gollark: Well, in most cases, if an error happens, a function needs to exit early, no?
