71 species of Aleurocystidiellum and Aleurodiscus s. lato are described and illustrated, mainly on basis of types or authentic specimens. Dichotomous and synoptic keys are provided for all species and related genera. A nomenclator to all names published in the genera is provided. Generic divisions within Aleurodiscus are shown to be untenable because of transitions in all series of characters used in previous attempts to subdivide the genus.
The following genera are placed in synonymy with Aleurodiscus: Acanthophysellum, Acanthophysium, Gloeosoma, Acanthobasidium and Aleurobotrys.
Aleurodiscus andinus Nunez & Ryvarden, Aleurodiscus cupulatus, Nunez & Ryvarden, Aleurodiscus fuegianus Nunez & Ryvarden, Aleurodiscus microcarpus Nunez & Ryvarden, Aleurodiscus parvisporus Nunez & Ryvarden and Aleurodiscus rimulosus Nunez & Ryvarden are described as new.
The following combinations are proposed: Aleurodiscus antarcticus (Spegazz.) Ryvarden, Aleurodiscus bisporum (Boidin & Lanq.) Nunez & Ryvarden, Aleurodiscus buxicola (Boidin & Lanq.) Nunez & Ryvarden, Aleurodiscus phragmitis (Boidin & Lanq.) Nunez & Ryv., Aleurodiscus propinquum (Boidin & Gilles.) Nunez & Ryvarden, and Aleurodiscus thoenii (Boidin & Gilles) Nunez & Ryvarden.
