New records of plant parasitic Asterinaceae (Dothideomycetes, Ascomycota) with intercalary appressoria from Central America and Panama

Abstract

New records of species of Asterinaceae with intercalary appressoria infecting plants in Central America and Panama are described and illustrated in detail. New records are Asterolibertia licaniicola on the new host Licania arborea (Chrysobalanaceae), Asterolibertia nodulosa on the new hosts Oxandra venezuelana and Xylopia sp. (Annonaceae), and Cirsosia splendida on the new hosts Chrysobalanus icaco and Hirtella triandra (Chrysobalanaceae). The teleomorph C. splendida is linked for the first time to the asexual morph Homalopeltis chrysobalani based on morphological observation. For the presented fungi an identification key is provided and infection strategies are discussed. Nomenclatural novelties are introduced, Leprieuria radiata becomes a synonym of H. chrysobalani and Asterina nodulifera is recombined into Asterolibertia nodulifera.

Additions to the genera Asterolibertia and Cirsosia (Asterinaceae, Asterinales), with particular reference to species from the Brazilian Cerrado

“…Asterolibertia campograndensis differs from the species previously reported on Chrysobalanaceae ( Table 1 ) ( Arnaud 1918 , Hansford 1947 , 1949 , 1955 , Müller & von Arx 1962 , Hosagoudar 2010 , Hofmann & Piepenbring 2014 , Farr & Rossman 2015 ). It is closest to A. parinarii , which has smaller appressoria and ascospores, narrower hyphae, and ellipsoid to subglobose asci.…”

“…A total of 15 species and one variety of Cirsosia have been described on six different host families ( Hosagoudar 2010 , Hofmann & Piepenbring 2014 , Farr & Rossman 2015 ): Dipterocarpaceae (5 species); Arecaceae (4); Chrysobalanaceae (3, including the new variety described here); Malpighiaceae (2); and Burseraceae and Lauraceae (1 on each; Table 4 ). There is no record of the same Cirsosia species being found on two different host families ( Hosagoudar 2010 , Farr & Rossman 2015 ).…”

“…Four of these were recorded from Brazil: A. couepiae on Couepia grandiflora, A. licaniae and A. licaniicola on Licania sp., and A. peruviana on Licania macrophylla . Additionally, A. nodulifera was recorded on Angelesia splendens from the Philippines, A. parinarii on Parinari subcordata from the Democratic Republic of the Congo, and A. schroeteri on Chrysobalanus icaco from India ( Arnaud 1918 , Hansford 1947 , 1949 , 1955 , Müller & von Arx 1962 , Hosagoudar 2010 , Hofmann & Piepenbring 2014 , Farr & Rossman 2015 ).…”

“…Asterolibertia peruviana has narrower appressoria, larger ascomata that are not fringed at the margins, and smaller appressoria and ascospores. Asterolibertia schroeteri differs in the larger ascomata with an irregular fissure, the absence of pseudoparaphyses, and larger asci and ascospores ( Tables 1 – 2 ) ( Arnaud 1918 , Hansford 1947 , 1949 , 1955 , Müller & von Arx 1962 , Hofmann & Piepenbring 2014 ).…”

Cirsosia humboldtigena sp. nov. (Lembosiaceae, Ascomycetes) on Humboldtia vahliana from Kerala, India

“…al. 2011, Hofmann & Piepenbring 2014, Farr & Rossman 2015, Firmino et al 2016: Dipterocarpaceae (5 species), Arecaceae (4), Chrysobalanaceae (3, including one variety), Malpighiaceae (2), Burseraceae (1) and Lauraceae (1). There is no record of the same Cirsosia species being found on two different host families (Hosagoudar 2010, Farr & Rossman 2015, Firmino et al 2016.…”
