A new species of Lachnum on Spartina alterniflora

Abstract

Lachnum spartinae is described as a new species of Lachnum (Hyaloscyphaceae) occurring on Spartina alterniflora (smooth cordgrass) from the salt marsh ecosystem of Sapelo Island, Georgia, USA. It forms apothecia on the standing dead shoots of S. alterniflora after or during cold rainy spells. It is believed to be part of the fungal community involved in the decomposition process of the cordgrass.
