Three Rinodina species new to China

Abstract

Rinodina ascociscana, R. subminuta, and R. trevisanii are reported as new to China. A detailed description of each species is provided, and comparisons with related species are made.

Two New Species in the Family Cunninghamellaceae from China

“…The species C. intermedia was nominated with the sporangiola being intermediate among four species [ 41 ]. The sizes of sporangiola in the new species C. globospora (9.09–14.73 µm diameter) are smaller and more uniform than those in C. intermedia (8.00–23.00 µm diameter) [ 22 ]. And, colonies are gray-brownish in C. globospora but “Hair Brown” in C. intermedia [ 22 ].…”

“…The sizes of sporangiola in the new species C. globospora (9.09–14.73 µm diameter) are smaller and more uniform than those in C. intermedia (8.00–23.00 µm diameter) [ 22 ]. And, colonies are gray-brownish in C. globospora but “Hair Brown” in C. intermedia [ 22 ]. Except for these discrepancies, they are similar in other characteristics, such as branched and septate hyphae, fingerlike rhizoids, and long primary branches [ 22 ].…”

“…Modified synthetic mucor agar (SMA: dextrose 20 g, asparagine 2 g, KH 2 PO 4 0.5 g, MgSO 4 ·H 2 O 0.25 g, thiamin chloride 0.5 mg, agar 20 g, 1000 mL distilled water, pH7) was used for morphological studies and maximum growth temperature tests [ 22 ]. For morphological observation, cultures were incubated at 28 °C for 9 d, and daily examined under a microscope (Axio Imager A2, Carl Zeiss, Oberkochen, Germany); while for determining maximum growth temperature, they were initially incubated at 30 °C for 2 d, and then the incubation temperature increased until the colonies stopped growing.…”

“…They are also mainly isolated from soil and grow optimally from 23 to 28 °C. Traditional morphologies for the classification of this genus include colonies, sporangiophores, vesicles, and sporangiola [ 22 ]. It is now comprised of 14 species and three varieties [ 22 , 23 ].…”

Two new Rinodina lichens from South Korea, with an updated key to the species of Rinodina in the far eastern Asia

“…The Rinodina has been studied in Europe (Mayrhofer and Poelt 1979;Giralt et al 1995;Giralt 2001;Mayrhofer and Moberg 2002), North America (Sheard and Mayrhofer 2002;Sheard 2004Sheard , 2010Sheard , 2018Sheard et al 2011Sheard et al , 2012Lendemer et al 2012Lendemer et al , 2019Morse and Sheard 2020), islands of South America (Bungartz et al 2016), Australia to New Zealand (Mayrhofer 1983(Mayrhofer , 1984bKaschik 2006;Elix 2011;Elix et al 2020), Asia to Russian Far East (Mayrhofer 1984a;Galanina et al 2011;Lendemer et al 2012;Sheard et al 2017;Galanina et al 2018;Galanina and Ezhkin 2019;Zheng and Ren 2020;Galanina et al 2021;Kumar et al 2021), and South Africa (Matzer and Mayrhofer 1996;Mayrhofer et al 2014). Molecular works have been accomplished over the continents (Grube and Arup 2001;Wedin et al 2002;Nadyeina et al 2010;Resl et al 2016).…”
