Eutypella oregonensis ≡ Eutypella oregonensis Wehm. Pap. Mich. Acad. Sci. 11: 163 (1930)

Description.

See Trouillas et al. (2010).

Note.

The strains of Diatrype oregonensis (DPL200, CA117) generated from Trouillas et al. (2010) grouped in Diatrypella s. str. Diatrype oregonensis was erected in 1930 as Eutypella oregonensis ( Kauffman 1930). No available sequences from type material were found. After re-examination of holotype specimen of Diatrype oregonensis , Trouillas et al. (2010) introduced two strains of Diatrype oregonensis (DPL200 and CA117). Although neither of these strains are ex-type, they are, the most authoritative strains. Here, we tentatively transfer Diatrype oregonensis to Diatrypella as Diatrypella oregonensis , based on the phylogenetic analyses (Fig. 1 ). Diatrypella oregonensis is similar to D. pseudooregonensis in having 8-spored asci ( Rappaz 1987; Trouillas et al. 2011). Nevertheless, we consider that the number of ascospores as a basis for distinguishing Diatrypella from Diatrype is not useful.

ML bootstrap supports (≥ 70 %) and Bayesian posterior probability (≥ 0.90) are indicated as ML / BYPP. The tree is rooted to Kretzschmaria deusta (CBS 826.72) and Xylaria hypoxylon (CBS 122620). Ex-type strains are in red. Newly generated strains are in black bold.
