Notes.

Hou and Piepenbring (2007) described Therrya abieticola on Abies sp. in the genus Therrya Sacc. because the shapes of asci, ascospores, and paraphyses of Th. abieticola are similar to those of the type Th. pini (Alb. & Schwein.) Höhn. ( Reid and Cain 1961; Hou and Piepenbring 2007). However, Hou and Piepenbring (2009) mentioned that Th. abieticola differs from the known species of Therrya by having aseptate ascospores.

Our phylogenetic analysis shows that sequences of Th. abieticola form a well-supported clade (MLB = 100 %, MPB = 91 %, PP = 1.00) together with sequences of N. nematoidea and are distantly related to type species of Therrya , Th. pini . Based on morphological characteristics and phylogenetic analyses, Th. abieticola is transferred here to the new genus Neotherrya . For a detailed description of this species see Hou and Piepenbring (2007).
