New records and an updated key of Pyrenula from India

Abstract

Pyrenula andina, P. atropurpurea, P. bahiana , P. caracasana, P. macrospora, P. massariospora, P. pseudobufonia , P. subducta, P. subgregantula and P. tristissima are described as new records for Indian lichen flora. An updated key to all Pyrenula species so far known from India is also presented.

Three new Pyrenula species with 3-septate ascospores with red or orange oil when over-mature (Ascomycota, Pyrenulales, Pyrenulaceae) from China

“…This new species is similar to Pyrenula thailandica , P. bahiana and P. concastroma in having 3-septate ascospores with red or orange oil when over-mature. It differs from P. thailandica by an inspersed hamathecium and larger ascomata, which are in the latter species 0.6–1.1 mm wide ( Aptroot 2012 ; Aptroot et al 2012 , 2013 ; Ingle et al 2018 ). This new species differs from P. bahiana by larger ascospores, which are in the latter species 26–33(–35) × 10–13(–15) μm ( Malme 1929 ; Aptroot 2012 ; Aptroot et al 2013 ; Ingle et al 2018 ).…”

“…Since then, many new species of Pyrenula have been described and the genus now comprises ca. 238 species ( Aptroot 2012 , 2021 ; Aptroot et al 2018 ; Ingle et al 2018 ; Miranda-González et al 2022 ; Mishra et al 2022 ; Lücking et al 2023 ; Soto-Medina et al 2023 ), of which 41 species have so far been found in China ( Aptroot 2012 , 2021 ; Wang et al 2018 ; Fu et al 2018 , 2019 ; Wei 2020 ; Xie et al 2021 ).…”

Pyrenula chlorospila (Nyl.) Arnold (Pyrenulaceae), a new addition to lichen biota of India

“…Pyrenula species mostly prefer to grow on the smooth bark of Alnus, Quercus, and Ficus species (Ingle et al 2018), and in India, most Pyrenula species have been found on the smooth bark of Lannea sp. and some on the bark of species of Artocarpous, Mangifea, Michelia, Polyalthia, and Ricinus.…”

“…Each asci bears eight spores. Ascospores are brown and transversely septate or muriform, with or without lichexanthone and anthraquinones (Awasthi 1991, Ingle 2018. Upreti (1990Upreti ( , 1991aUpreti ( , 1991bUpreti ( , 1992Upreti ( , 1993 made extensive revisionary studies on the Pyrenula of India and described several new species, as well as reports of species from the country.…”

A new record of pyrenocarpous lichen to the Indian biota

“…Jagadeesh et al (2005) revised the genus Pyrenula and reported Pyrenula subcylindrica Jagadeesh & Upreti new to science from India. Recently, Ingle et al (2018) listed Pyrenula taxa from India and reported 77 species including 10 new records from the country.…”
