Ardhachandra, a new genus of the Hyphomycetes

Abstract

A dematiaceous Hyphomycete collected on Ixora leaf litter from India is described. The fungus produces two types of conidia: lenticular and selenoid, both typically bivalved with a germ slit, blastic, solitary, terminal on the conidiophore and its successive sympodial proliferations. It is conspecific with the Tanzanian collection of a fungus assigned by Pirozynski in 1972 to Rhinocladiella critaspora Matsushima and designated the holotype of a new species of Pseudobeltrania, P. selenoides, by de Hoog in 1977. Pseudobeltrania selenoides is made the type of a new genus Ardhachandra; Rhinocladiella critaspora Matsushima (= Pseudobeltrania critaspora (Matsushima) de Hoog) is transferred to Ardhachandra as A. critaspora (Matsushima) comb. nov.

Rare hyphomycetes from freshwater environments from Chapada Diamantina, Bahia, Brazil

“…Ardhachandra was erected by Subramanian and Sudha in 1978 with the type species A. selenoides. The genus is represented by six species (Mel'nik 2012) with conidia selenoid, fusiform or lenticular, produced singly and successively by conidiogenous cells with prominent denticles (Subramanian & Sudha 1978). Ardhachandra aequilatera is easily distinguished from the type species that forms selenoid conidia (Subramanian & Sudha 1978).…”

Ardhachandra aequilatera is easily distinguished from the type species that forms selenoid conidia (Subramanian & Sudha 1978). Ardhachandra prolatofusiformis J.L.Chen & Tzean is close to A. aequilatera but has longer conidia which are asymmetrical (unequal-sided) in front view (Chen & Tzean 1995).…”

Aero-Aquatic Fungi Colonizing Decaying Leaves in Woodland Swampy Pools of Aukštadvaris Regional Park (Lithuania)

“…Originally, this fungus was described from Solomon Islands by MAtsushiMA (1971) as Rhinocladiella cristaspora, but later suBrAMAniAn & suDhA (1978) transferred it to Ardhachandra and the new name was also adopted by MAtsushiMA (1980). This saprobic fungus is able to colonize a wide range of substrates and although it was mainly known as foliicolous on debris of deciduous plants (MAtsushiMA, 1971(MAtsushiMA, , 1980suBrAMAniAn & suDhA, 1978), recently it has been isolated from decaying needles (iWAMoto & tokuMAsu, 2001) and from a fruit body of an aphyllophoralean fungus in Japan (WAtAnABe et al, 2003). It seems to be cosmopolitan, currently is known from Asia, Africa, Australia, North and South America and Europe (MAtsushiMA, 1971(MAtsushiMA, , 1980suBrAMAniAn & suDhA, 1978;WAtAnABe et al, 2003;onoFri & cAstAgnolA, 1983;hyDe, 1996;PAsquAletti et al, 2006;BArBosA et al, 2008;rAjA et al, 2009).…”
