Assessment Notes

Taxonomic notes

The genus Periconia was described by Tode in 1791 with Periconia lichenoides Tode as type species. Afterwards, the type specimen was lost and only Tode’s drawings were left available for taxonomical comparison.  Persoon (1801) described P. byssoides Pers this species is caracterized by conidiophores dark brown, erect, straight or slightly flexous, simple, thick-walled, conidiogenous cells hyaline, ellipsoidal to spherical, monoblastic to polyblastic, conidia cantenate, forming chains, spherical, brown, verrucose (Persoon, 1801; Mason; Ellis, 1953; Ellis, 1971; Markovskaja; Kačergius, 2017).

Why suggested for a Global Red List Assessment?

Periconia byssoides has great ecological value as well as anti-tumour and antifungal properties, further studies on the chemical and biotechnological scale are needed to expand the importance of this group.

Geographic range

Distribution: cosmopolitan

Population and Trends

Periconia byssoides has distribution cosmopolitan; there are 174 names to genus, currently. This species is found in stems and leaves dead in Argentina (Carmaran; Novas, 2003), Cuba and Venezuela (Urtiaga, 1986), China (Zhuang, 2005), Malaysia (Williams;Liu, 1976), Papua New Guinea (Shaw, 1984), Zambia (Lenne, 1990), Poland (Mulenko et al., 2008), Lithuania (Markovskaja; Kacergius, 2014).

Research needed

Although Periconia byssoides has a wide distribution in the world and in Brazil, more research is needed in several regions and biomes of the world, because some researches have been done showing its antitumoral activity and antifungal properties (Lin et al., 2006; Yamada et al., 2007).

Use and Trade

Pericosines A–E 1–5 isolated of Periconia byssoides shown stereostructures, have been elucidated on the basis of spectroscopic analyses, including 1D and 2D NMR techniques, and X-ray analysis. Compounds 1–3 exhibited significant growth inhibition against tumour cell lines. Pericosine A 1 also showed significant in vivo tumour inhibitory activity (Yamada et al., 2006, 2007). Other studies with isolation and structure determination of Peribysins have elucidated by Inose et al. (2018), Athawale et al. (2020).
An extracellular b-1,3-glucanase with antifungal properties was secreted of Periconia byssoides. The purified b-1,3-glucanase was capable of degrading cell walls, and inhibiting mycelia growth and spore germination of plant pathogenic fungi including Fulvia fulva, Fusarium sp. and Rhizoctonia solani. The N-terminal amino acid residues of the purified b-1,3-glucanase are LKNGGPSFGA,  suggest it may be a novel member of the fungal b-1,3- glucanases (Lin et al., 2007).
