Sclerococcum fissurinae Pérez-Ort. (2020)

Sclerococcum fissurinae is a species of lichenicolous fungus in the family Dactylosporaceae. Found in Alaska, it was formally described as a new species in 2020 by Sergio Pérez-Ortega. The type specimen was collected in the Hoonah-Angoon Census Area, just outside of Glacier Bay National Park. Here it was found growing on the script lichen species , which itself was growing on the bark of an alder tree. The specific epithet refers to its host.^[1]

The fungus forms black, circular apothecia on its lichen host that are up to 0.6 mm in diameter. Its asci are eight-spored, measuring 25–33 by 8–12 μm. The ascospores are brown with an ellipsoid shape, and typical dimensions of 8–12 by 3–4 μm; they usually have three septa, although sometimes only one or two occur. A morphologically similar species in the same genus is but in this fungus, which has a different host, the ascospores are slightly larger (9–15 by 3.5–5 μm).^[1]
