Abstract

Abstract. The new lichenicolous fungus Zwackhiomyces polischukii

Pronectria gromakovae, a new lichenicolous fungus on Lecanora populicola and notes on other records from Kharkiv region (Ukraine)

“…Illosporiopsis christiansenii is a common species in Ukraine, but there is no previous report from Kharkiv region (Darmostuk and , Khodosovtsev and Darmostuk 2017b, Darmostuk and Sira 2020.…”

“…This species is rarely collected but probably overlooked , Khodosovtsev and Darmostuk 2017b, Darmostuk and Sira 2020.…”

Didymocyrtis trassiisp. nov. and other lichenicolous fungi onCetraria aculeata

“…Note. This species was recently collected on Cetraria aculeata in Lower Dnipro dunes (Khodosovtsev & Darmostuk 2017). The fungus is recognizable by its black necrotic spots covered by numerous pseudothecia.…”

“…Despite the wide distribution of this bipolar lichen (Printzen et al 2013), data regarding its associated fungi are limited. So far six lichenicolous species have been reported: Clypeococcum cetrariae Hafellner (Khodosovtsev & Darmostuk 2017), Endococcus parmeliarum Etayo (Brackel 2015), Katherinomyces cetrariae Khodos., Sphaerellothecium aculeatae Khodos. et al (Khodosovtsev et al 2016), Lichenopeltella cetrariicola (Nyl.)…”

“…We previously reported three species from Ukrainian sand dunes, viz. Clypeococcum cetrariae, Katherinomyces cetrariae and Sphaerellothecium aculeatae (Khodosovtsev et al 2016;Khodosovtsev & Darmostuk 2017), two of which were described as new. Yet in different parts of the sand dunes of Lower Dnipro, an additional coelomycetous fungus with large hyaline aseptate conidia was collected that at first glance resembled Didymocyrtis foliaceiphila (Diederich et al) Ertz & Diederich.…”
