Based on opportunistic collections of fungi in Panama, two species of Diatrypaceae (Xylariales) are described and illustrated. One of them, Eutypella semicircularis, found twice on branches probably belonging to Alnus acuminata, is new to science. It differs from known species of Eutypella and Peroneutypa with strongly allantoid or semicircular ascospores, such as E. crustata and P. curvispora, in having larger ascospores that sometimes almost form a circle and broader stromata, among other differences. Molecular data of the ITS rDNA region show that the new species is a sister taxon of Eutypella cerviculata, the type species of the genus Eutypella. Diatrype bermudensis on stems of Guadua angustifolia is reported from Panama for the first time, being known up to now apparently only from Bermuda.
基于在巴拿马的机会性真菌收集，描述并图示了两个肉座菌科（Xylariales）的物种。其中一种，Eutypella semicircularis，两次在可能属于赤杨属（Alnus acuminata）的树枝上被发现，是科学上的新发现。它与已知的具强烈陀螺形或半圆形子囊孢子的 Eutypella 和 Peroneutypa 物种不同，如 E. crustata 和 P. curvispora，具有更大的子囊孢子，有时几乎形成一个圆圈和更宽的子座，还有其他差异。ITS rDNA 区域的分子数据表明，该新种是 Eutypella cerviculata 的姐妹分类群，Eutypella cerviculata 是 Eutypella 属的模式种。Diatrype bermudensis 曾被认为仅分布于百慕大，现首次报道在巴拿马的 Guadua angustifolia 茎上被发现。
