Australasian sequestrate Fungi 20: Russula scarlatina (Agaricomycetes: Russulales: Russulaceae), a new species from dry grassy woodlands of southeastern Australia

Abstract

Russula scarlatina sp. nov. is a common sequestrate fungus found in the dry sclerophyll Eucalyptus woodlands of southeastern Australia. Basidiomata are hypogeous or sometimes emergent; they are scarlet in youth and become dark sordid red or brown with advanced age. Historically, this species would have been placed in the genus Gymnomyces, but in light of recent revisions in the taxonomy of sequestrate Russulaceae, we place it in the genus Russula. It is morphologically distinct from other sequestrate species of Russula because of its scarlet peridium and unusual cystidial turf in youth. It has been collected only in dry grassy woodlands and open forest habitats of southeastern Australia.

“…Considering related publications, major colorants in the edible Lactarius mushrooms may be azulene and their structural formula are given in Figure 1. Mycologists have so far identified about 120.000 fungal species [30], but this number increases day by day with the detection of new species [31][32][33][34][35][36]. However, the number of fungal species in the world is estimated to be 2.2-3.8 million [37].…”
