Microporellus is a genus of poroid fungi in the family Polyporaceae.
Taxonomy
The genus was circumscribed by American mycologist William Murrill in 1905 with Microporellus dealbatus as the type species. Murrill intended to the genus to contain polypores with stipes. The generic concept was emended in 1985 by David and Rachenberg. After examining the type of Polyporus dealbatus, they reported for the first time the presence of dextrinoid skeletal hyphae and incrusted cystidia, a unique combination of characters in the Polyporales. Ryvarden and Dhandha had previously (1975) used this combination of characters to erect Cystostiptoporus, a genus that had Cystostiptoporus indicus as the type species. Due to the Principle of Priority, the earlier-published name is preferred, and Cystostiptoporus was therefore sunk into synonymy with Microporellus. In 1987, E. J. H. Corner further emended Microporellus by including species without cystidia, and also some trimitic species. Decock broadened the genus in 2001 by including two species with stipes: Microporellus celtis, and M. peninsularis. The latter fungus has since been transferred back to its original genus Vanderbylia.
