Three new species of Hymenoscyphus from tropical China
Three new species of Hymenoscyphus collected from tropical regions of China are described and illustrated. Hymenoscyphus magnicellulosus possesses whitish sessile apothecia with large-celled textura prismatica at flank and isodiametric cells at the base, and inequilateral
ellipsoid ascospores 12.5–19(–22) × 4.5–6.7 μm. Hymenoscyphus uniseptatus has white stipitate apothecia, rectangular ectal excipular cells, broadly clavate asci, and broadly fusoid 1-septate ascospores 16.7–20.5 × 5–6.5 μm. Hymenoscyphus
yunnanicus is characterized by cream to light yellow stipitate apothecia, narrow ectal excipular hyphae, and multiguttulate fusoid ascospores 16.5–19.5 × 5–5.6 μm. Comparisons were made among the new species and their morphologically similar fungi.
