Summary: | Two new wood-rotting fungi in the family Hymenochaetaceae,
and
, are described and illustrated from tropical China based on morphological characteristics and molecular data. It is worth to mention that both of them grow on
which is a kind of angiosperm tree distributed in tropical regions.
is characterised by perennial, pileate, triquetrous basidioma with yellowish brown fresh pores which becoming honey yellow with silk sheening upon drying, a dimitic hyphal system in trama and monomitic in context, and subglobose basidiospores measuring 4.8-5 × 4-4.1 μm.
is characterised by annual, resupinate basidioma with a clay buff hymenophore, a dimitic hyphal system, absence of tomentum and cortex, presence of subulate setae, absence of cystidia, presence of cystidioles and simple hyphidia, and oblong ellipsoid basidiospores measuring 5.2-5.8 × 2.5-2.8 µm. The phylogenetic analyses based on ITS + nLSU rDNA sequences confirm the placement of two new species respectively in
and
. Phylogenetically closely related species to the two new species are discussed. |
