An overview of the genus Coprotus (Pezizales, Ascomycota) with notes on the type species and description of C. epithecioides sp. nov.

Abstract

In a mycological research performed in the Sjeverni Velebit National Park, Croatia, a new species of Coprotus was discovered, described here as C. epithecioides. Along with the microscopic examination, phylogenetic analysis of the type material, based on ITS and LSU sequences, was performed in order to evaluate its relationship with the type species, C. sexdecimsporus. The type species was sequenced in this study for the first time, providing ITS and LSU sequences from two separate collections which displayed differences in macroscopic characters and content of paraphyses. An extended description of C. sexdecimsporus based on Croatian material is also provided. A worldwide identification key to the species assigned to the genus Coprotus is presented, along with a species overview, containing a data matrix. The phylogenetic position of Coprotus in the Boubovia-Coprotus clade within Pyronemataceae s.l. is discussed. Coprotus sexdecimsporus is also reported here as new to the Croatian mycobiota.

Fungal diversity notes 1036–1150: taxonomic and phylogenetic contributions on genera and species of fungal taxa

“…97 Phylogram generated from maximum likelihood analysis based on combined ITS, LSU, SSU and TEF1-a sequence data for Boubovia species and several closely related genera in Ascodesmidaceae. Related sequences are taken from Perry et al (2007), Hansen et al (2013), Lindemann et al (2015 and Kušan et al (2018). Sixteen strains are included in the combined analyses which comprise 3584 characters (669 characters for ITS, 890 characters for LSU, 1043 characters for SSU, 982 characters for TEF1-a) after alignment.…”

“…& R. Kristiansen are known. Three species have available molecular data(Perry et al 2007;Hansen et al 2013;Kušan et al 2018).Boubovia gelatinosa M. Zeng, Q. Zhao & K.D. Hyde, sp.…”

“…Reagents such as 5% KOH and Iodine (IKI) were used as investigation media. Identification was performed with the aid of the relevant literature (Kimbrough et al, 1972;Thind et al, 1978;Bell, 2005;Thompson 2013;Melo et al, 2015;Kušan et al, 2018). Coprotus ochraceus (P. Crouan & H. Crouan) J. Moravec Macroscopic and microscopic features: Apothecia scattered to gregarious, without stalk, globular-discoid, pale yellowish to orange or ochraceous, 0.5-1.8 mm diam., smooth and without hairs (Fig.…”

“…Members of the genus have a coprophilous ecology and are characterised by an oblate to discoid or lenticular, whitish to yellowish or translucent apothecia; operculate, non-amyloid, eight to 256 spored asci; hyaline, smooth, de Bary bubbled and aguttulate ascospores; filiform, hyaline or pigmented paraphyses, generaly bent to uncinate or swollen at the apex; and an excipulum mainly composed of globose to angular cells (Kimbrough et al, 1972;Bell, 2005). Kušan et al (2018) gives the accepted species number in the genus Coprotus as 29. On the other hand IndexFungorum (2022) currently list 26 conformed Coprotus species.…”

Cytological studies reveal high variation in ascospore number and shape and conidia produced directly from ascospores in Morchella galilaea

“…In ascomycetes, species with varying numbers of spores per ascus were previously reported (Yao and Spooner, 2000;Bonito et al, 2010;Kušan et al, 2018;Pfister and Healy, 2021). However, variation in spore number within asci from the same species and from the same fruiting body are more rarely reported.…”
