Morphological characteristics and phylogenetic analysis reveal <i>Helvellosebacinafilicata</i> sp. nov. and <i>Sebacinaaciculicola</i> sp. nov. in Sebacinales from southwest China.

ABSTRACT: Morphological characteristics and phylogenetic analyses based on ITS and nLSU sequences reveal two new species of Sebacinaceae from southwest China, viz. Helvellosebacinafilicata sp. nov. and Sebacinaaciculicola sp. nov. The two species have similar micromorphology characterized by clampless hyphae, hyphidia with simple septa, longitudinally septate, 4-celled, ovoid to subglobose basidia, and broadly ellipsoid to ovoid basidiospores. However, H.filicata is characterized by cartilaginous to gelatinous, white to cream, sometimes semi-transparent basidiomata; basidiospores measuring 8.6-9.9 × 5.8-7.6 μm; and growth on dead ferns. S.aciculicola is characterized by coriaceous, white-to-cream basidiomata; basidiospores measuring 10.2-12.9 × 6.3-8.7 μm; a
