Could find no way to annotate this in MEGA—just learning to use it. The top limb is A. americana. Lower limb is A. angiospermarum including JX065151, JX065152 and JX065163 which were sequenced for Looney et al. 2013 and called A. americana decidiuous clade which is now known to be a separat...

Used references: I gave a copy of the chromatogram to Brian Looney who said: “This is definitely in the A. americana complex. It looks to be more closely related to the Chinese species growing on conifer wood.”

as it occurred on coniferous wood. The same study proposed A. angiospermarum for A. americana on deciduous wood: “On the basis of the host, distribution, and molecular data of
the A. americana angiosperm clade, we consider it to be an
independent species; it is described as A. angiospermarum,
although it does not have distinct morphological differences
from A. americana s. str. A. angiospermarum grows on angiosperms
and has a distribution in North America only, while
A. americana s. str. is a common species on gymnosperms and
has a wide distribution in North America and Asia (Looney
et al. 2013; Malysheva and Bulakh 2014; Wu et al. 2014).”

The type for A. americana was collected in NA (Quebec) on Abies. The type for A. angiospermarum was collected in NA (Ct.) on Quercus.
