Morphology
The phrase is a straightforward taxonomic noun phrase: 'genus' (a biological rank) combined with the taxon name 'Rhizoctinia' directly signals a group of related fungi. Although the subject is technical, the compositional structure is standard and cross-linguistically recognizable, so a learner who knows both constituents can infer the meaning.
Etymology
Genus Rhizoctinia comes from the part rhizo- meaning 'root' and the second part -ctinia that suggests 'harm', because many of these fungi attack plant roots. So the name gives the simple image of a 'genus' of fungi that damage roots, which explains why scientists used it before they moved some species to other groups when they learned their full life stages.
