Diorygma archeri is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. [1] Found in Vietnam, it was formally described as a new species in 2013 by Santosh Joshi and Jae-Seoun Hur. The type specimen was collected from Yok Đôn National Park ( Đắk Lắk province) at an altitude of about 760 m (2,490 ft). The species epithet honours Australian lichenologist Alan W. Archer. [2]
Diorygma archeri has a flat thallus that is usually white or grayish-green in color and up to 800 μm thick. The outer layer of the lichen (the pseudocortex) is distinct, reaching up to 30 μm. The algal layer is well-developed and about 50–60 μm thick. The inner layer, the medulla, is white and thick, with crystals scattered throughout it. [2]
The fruiting bodies of the lichen, called ascomata, are numerous and can vary in shape, with some being short and curved while others are more branched. They are covered by a brownish or reddish-brown layer that is surrounded by a raised, irregular margin. The hymenium, which is the part of the ascomata that contains the spores, is hyaline and can be seen to be violet-blue when treated with certain chemicals. The spores themselves are oval to elliptic in shape, multicellular, and range in size from 150 to 255 x 53 to 85 μm. [2]
Diorygma archeri contains protocetraric acid, a lichen product that can be detected using thin-layer chromatography. [2]
Diorygma archeri is comparable to Diorygma pruinosum, but the two differ in several ways. Specifically, D. archeri has a thick, distinctly corticate body that is grayish-green in color and contains a well-developed medulla. The apothecial disc of D. archeri is only slightly open, and its proper exciple is not carbonized. Additionally, Diorygma archeri has larger ascospores than D. pruinosum. [2]
