Abstract

Since the publication of Amanita strobilaceovolvata by Beeli in 1935, several taxonomic papers have reported many individuals of Amanita having a volva with pyramidal warts from Africa as A. strobilaceovolvata. Such a grouping has pulled away the circumscription of the species from its original description. To address this, we are providing macro- and micro-morphological characters of the species and describing a new species, namely Amanita griseostrobilacea with a strobiloid volva. Although these two species have a strobiloid volva, A. strobilaceovolvata can be recognized by its yellow cap, lamellae, annulus and squamules, and globose spores while A. griseostrobilacea has a whitish grey cap, a white stipe and annulus and white lamellae, and ellipsoid to broadly ellipsoid spores. Volval inner part Amanita strobilaceovolvata is made of a mixture of elongated, non-septate and non-branched hyphae with non-septate and branched hyphae while that of A. griseostrobilacea is composed of a mixture of elongated and septate hyphae with inflated hyphae.
