Chaenothecopsis jordaniana is a species of corticolous, pin lichen.

Description

The lichen lacks a thallus and can be found on the bark of Eastern White Cedar. Apothecia are singular or in groups of 2-7, black or greenish, and epruinose^[1]. Apothecia range from 0.14-0.28 mm tall, and 0.11-0.30 mm across, and have an absent or extremely short stock, 0.02-0.08mm in diameter; they are visible with a 20X hand lens^[1]. Asci are cylindrical, 34-50 μm long and 2.5-4.5 μm wide^[1]. Ascospores are septate, pale brown, ellipsoidal, 6.0-10.5 μm long and 2.0-3.0 μm wide^[1].

Habitat

Chaenothecopsis jordaniana is found only in Minnesota. Most commonly located on the bark of the Eastern White Cedar in narrow ridges^[1]. The majority of trees it is found on have weathered white and grayish bark. Apothecia are found where grayish bark transitions to a brown hue, similar to younger tree bark^[1].

Etymology

Chaenothecopsis jordaniana is named after Dr. Peter Albion Jordan (1930-2017)^[1].
