Morphological and Phylogenetic Analyses Reveal a New Species of Anthracophyllum (Omphalotaceae, Agaricales) in Zhejiang Province, China

Abstract

During the investigations of macrofungi resources in Zhejiang Province, China, an interesting wood rot fungus was collected. Based on morphological and molecular phylogenetic studies, it was described as a new species Anthracophyllum sinense. A. sinense is characterized by its sessile, charcoal black and pleurotoid pileus; sparse, occasionally branches lamellae; oval basidiospores measuring (8–)9–11.2–13(–14) µm × (5–)6–6.6–8(–9) µm, with obvious spore tips; clavate basidia with obvious sterigmata; and non-heteromorphous cystidium. A. sinense established a separate lineage that was similar to A. archeri and A. lateritium in the phylogenetic tree.

Anthracophyllum sontraense (Omphalotaceae, Agaricales), a new species from Danang, Vietnam

“…& Broome) 8 , A. archeri (Berk.) 9 , A. glaucophyllum, A. pallidum 10 and A. sinense 11 . Several species assigned in Anthracophyllum were earlier classi ed in the genus Xerotus such as X. archeri, X. discolor, X. glaucophyllus, X. nigritus and X. proximus.…”

“…Up to now, only A. lateritium 12,13 and A. archeri 14 have been identi ed by both morphological and molecular methods. In addition, A. sinense, a very new species of Anthracophyllum accepted in January 2024, has also been recorded in China by those methods 11 . Recently, according to our previous study on the diversity of species composition of macrofungi belonging to the phylum Basidiomycota in Son Tra Nature Reverse (Danang city, Vietnam), 110 taxa belonging to 42 genera, 23 families, 10 orders and 3 classes of the phylum Basidiomycota have been recorded 15 .…”
