The Genera of Fungi—G3: Aleurocystis, Blastacervulus, Clypeophysalospora, Licrostroma, Neohendersonia and Spumatoria

Abstract

The current paper represents the third contribution in the Genera of Fungi series, linking the type species of fungal genera to their morphology and DNA sequence data, and, where possible, ecology. In this issue, we have focused on six genera, including macro-and microfungi, four of which the type species is epitypified. In addition, two new families within Pleosporales and Xylariales are proposed to accommodate two of them. The genera treated here include:

“…Resolving these generic and species concepts is thus of the utmost importance for plant health and global trade in food and fibre (Crous et al., 2015b, Crous et al., 2016a). The present project focused on genera of fungi that have members causing plant diseases (phytopathogenic), links to a larger initiative called the “The Genera of Fungi project” based on Clements & Shear (1931) (www.GeneraOfFungi.org, Crous et al., 2014a, Crous et al., 2015a, Giraldo et al., 2017), which aims to revise the generic names of all currently accepted fungi (Kirk et al. 2013).…”

“…Notes — The order Asterinales is characterised by epiphytic fungi, biotrophic parasites, with superficial non-ostiolate ascomata, opening irregularly at maturity; surface mycelium and haustoria are present in several genera ( Bezerra 2004 ). The Asterinales is composed by two families, Asterinaceae and Parmulariaceae ( Guatimosim et al 2015 , Giraldo et al 2017 ). Members of Asterinaceae are characterised by producing black colonies consisting of a brown mycelium on the leaf surface ( Guatimosim et al 2015 ).…”

“…Asexual morphs (hyphomycetous and coelomycetous) have been observed in some Asterinaceae ( Summerell et al 2006 , Hongsanan et al 2016 ). The conidia of Paraopeba schefflerae are formed in schizolytic conidiogenous cells while conidia of Alysidiella , Blastacervulus and Asterostomula are formed in sporodochial, acervular and pycnothyrial conidiomata, respectively ( Summerell et al 2006 , Giraldo et al 2017 ). Additionally, the appressorial cells are present in Paraopeba , but have not been observed in Alysidiella , Blastacervulus and Asterostomula ( Summerell et al 2006 , Giraldo et al 2017 ).…”

Bayesian inference analysis (alignment and tree were deposited into TreeBASE under accession number S21280) suggests that Paraopeba schefflerae is related to members of Asterinaceae , and represents a different genus in this family.…”

“…Notes — The genus Paraphysalospora is related to Clypeophysalospora and Neophysalospora ( Xylariales ), both occurring on Eucalyptus ( Crous et al 2014b , Giraldo et al 2017 ). Based on the ascospore shape, mucoid appendages and sporodochial asexual morph, Paraphysalospora clearly represents yet another genus in this complex.…”
