A NEW SPECIES OF LABROCARPON (ASTERINALES), A LICHENICOLOUS ASCOMYCOTA WITH SUBMURIFORM ASCOSPORES FROM INDIA

During lichenicolous fungal studies in India, lichen genus Ochrolechia was found infected with a black lirellate fungus. Critical microscopical examination of the fungus revealed that it is new species Labrocarpon , which differs from L. canariense having narrow exciple (15.0–20.0 µm vs 20.0–50.0 thick), 4-spored asci, 1-septate to submuriform, constricted ascospores larger l/w value [(2.5–)2.9– 3.4 –3.9(–4.5) (1.9–)2.1–2.5(–2.8)], habitat preference (corticolous saxicolous) and host selection ( Pertusaria ). The submuriforme described detail.
