The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00066 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

ABSTRAKT

This article presents data from morphological observations of mycelia of 40 monokaryotic and 11 dikaryotic collections of 3 medicinal Coprinellus species (C. disseminatus, C. micaceus, and C. xanthothrix). The growth rate, colony morphology, and micromorphological characteristics of mycelia and anamorphs on 1.5% malt-extract agar (MEA) and potato-dextrose agar (PDA) are described. Well-developed white, cottony-felt colonies, which later show creamy, yellowish to rusty brown pigmentation on mycelia and agar, were typical for the studied Coprinellus collections. Mycelial growth was denser on PDA than on MEA, whereas the average growth rate indicators (GRavr) were higher in dikaryotic isolates on MEA. Clamp connections were described only in dikaryotic isolates of C. disseminatus and C. micaceus; mycelia of C. xanthothrix had no clamps. Nonsporulating Ozonium-type anamorphic mycelia (with a rusty brown septate and parallel hyphal strands), a taxonomic feature characteristic of the clade Coprinellus, was present in the studied monokaryotic and dikaryotic collections, whereas Hormographiella-type sporulating anamorphs developed only in monokaryotic and dikaryotic isolates of C. xanthothrix. Yellowish-rusty-brownish regular hyphal loops were also observed in the collections of all 3 Coprinellus species. Allocyst-like hyphal swellings were observed in monokaryons of C. xanthothrix, and hyphocystidia were observed in dikaryons of C. micaceus. Hyphal loops and hyphal cystidia presumably were derived from Ozonium mycelia. Thick-walled, oval chlamydospores and chlamydospore-like swellings were described only in dikaryons of C. xanthothrix. Under these experimental conditions, primordia and fruiting bodies developed in dikaryons of C. xanthothrix on MEA and PDA, respectively, and in dikaryons of C. micaceus on MEA. The taxonomic significance of the mycelial and anamorphic characteristics of studied Coprinellus species was evaluated. They could be useful for identifying mycelial cultures during biotechnological cultivation.
