Carbacanthographis albolirellata
Carbacanthographis albolirellata is a species of bark-dwelling crustose lichen in the family Graphidaceae. It occurs in Tamil Nadu, India.
Taxonomy
The species was described as new to science in 2011 by Bharati Sharma and Pradnya Khadilkar, based on herbarium material held at the Ajrekar Mycological Herbarium. The holotype was collected in India, near Daisy Bank at Kodaikanal, on 25 January 1975. In their of the species, Sharma and Khadilkar separated C. albolirellata from close relatives by a completely, somewhat spores, and the absence of detectable lichen secondary metabolites. They also compared it directly with C. coccospora, which is similar in overall form but has smaller spores.Description
The thallus forms a thin, crust-like growth tightly attached to bark, and sits on the bark surface. It is yellowish brown, dull, and rough, with a warty texture and cracking; the colony edge is marked by a thin, black. The fruiting bodies are : black, elongated, slit-like structures that are dusted with white on the surface and black beneath. They are usually simple and straight to slightly curved, about 1–4 mm long, with rounded ends. The exposed is slit-like and lacks pruina. The is convergent and completely carbonized, including at the base, and no is present.Internally, the spore-bearing layer is clear, lacks granular inclusions, gives no reaction with iodine, and is 75–150 μm high; the paraphyses are unbranched. The are short and distinctly warty. Each ascus contains eight spores. The ascospores are hyaline and somewhat muriform, with 6–8 transverse septa and 1–2 longitudinal septa per segment, measuring 16–20 × 6–8 μm; in iodine they stain blue-violet. Chemical screening found no lichen substances.
