Abstract
Fomitiporella austroasiana, F. mangrovei and F. vietnamensis are described and illustrated as new species based on morphological characters and molecular evidence. They have annual to perennial, mostly resupinate basidiomata with grayish fresh pores, an indistinct subiculum, lack any kind of setae, have brownish, thick-walled basidiospores, and cause a white rot. The distinctive morphological characters of the new species and their related species are discussed. Phylogenies based on the nuclear ribosomal large subunit (28S) and the nuclear ribosomal ITS region show that these three new species form three distinct lineages in the Fomitiporella clade. A key to known species of Fomitiporella is given.
Highlights
Fomitiporella Murrill was described by Murrill (1907) with F. umbrinella as type
The genus is characterized by perennial, resupinate and adnate basidiomata, a thin subiculum, stratified tubes, and brown, subglobose basidiospores (Murrill 1907)
A previous phylogenetic study based on 28S DNA sequence data confirmed Fomitiporella as an independent genus within Hymenochaetaceae, with Phellinus caryophyllii (Racib.) G
Summary
The genus is characterized by perennial, resupinate and adnate basidiomata, a thin subiculum, stratified tubes, and brown, subglobose basidiospores (Murrill 1907). Xiao-Hong Ji et al / MycoKeys 30: 73–89 (2018). A previous phylogenetic study based on 28S DNA sequence data confirmed Fomitiporella as an independent genus within Hymenochaetaceae, with Phellinus caryophyllii (Racib.) G. During the past five years, many new species were revealed based on morphological characters and molecular data (Zhou 2014, Ji et al 2017). Ji et al (2017) broadened the concept of Fomitiporella to accommodate species with resupinate to effused reflexed and annual basidiomata
