Samples of a small coprinoid fungus were collected
from rice straw in Amol, north of Iran. Specimens
were transferred to PDA culture media and
basidiocarps were appeared after two weeks. Using
basidiocarps produced in laboratory, specimens were
identified as Coprinopsis urticicola
(Berk. &
Broome) Redhead, Vilgalys & Moncalvo based on.
(Knudsen & Vesterholt 2008, Uljé & Noordeloos
1997, Uljé 2005.
The characteristic features of specimens derived
from basidiocarps produced in culture media (PDA)
were as follows (Fig. 1):
Pileus 3–7 × 2–5 mm, ovoid to conical, then
expanded, white, veil breaking up in small, hairy-
floccose, pure white, then white and ochraceous
scales. Lamellae crowded, free, first white, then grey-
brown, finally blackish and deliquescent. Stipe up to
50 × 0.5–1 mm, cylindrical, white, flocculose at base,
fully covered by spores at upper part.
Spores 5.5–9 × 4.5–6 μm, ellipsoid or ovoid, often
with slightly conical base and rounded apex, with wide
germ pore, pale brown. Basidia 15–35 × 6–10 µm, four
spored. Pleurocystidia 50–120 × 10–35 µm, cylindrical,
oblong or fusiform. Cheilocystidia 30-80 × 10–18 µm,
ellipsoid, cylindrical, utriform, fusiform to conical. Veil
of elongate slightly thin-walled diverticulate elements.
Specimen examined. IRAN, Mazandaran Province,
Amol, on Rice (Oryza sativa L.), 15 June 2012, S.
Naeimi, IRAN 16086 F.
Coprinopsis urticicola
is a widespread but rare
species and known from Europe (e.g. Britain,
Netherlands and Poland) and North America (Uljé
2005). The species can be recognized by habitat
shape of velar remnants and morphology of spore and
basidiocarp shape of velar remnants and morphology
of spore and basidiocarp.

... Coprinopsis. Coprinopsis urticicola (Berkeley & Broome 1861: 376) Redhead, Vilgalys & Moncalvo (2001: 232), a species originally described from North America (Uljé 2005) and also reported from East Africa (Pegler 1977), Europe and Iran (Asef et al. 2015), seems to be close to C. minuta in having almost similar-sized basidiospores (5.5-9 × 4.5-6.5 µm), coralloid velar elements on the pileipellis, absence of clamp connections, and a lignicolous habitat. However, C. urticicola differs from C. minuta in having a pileus with woolly-hairy velar scales, basidia surrounded by 5-8 psuedoparaphyses, basidiospores with a conical base, utriform to subcylindrical pleurocystidia, and a pileipellis with strongly encrusted velar elements. ...
Two new species of Coprinopsis from Kerala State, India

  • Dec 2022
Two new species, Coprinopsis minuta and C. squamulosa, are described from Kerala State, India, on the basis of both morphology and molecular data. Comprehensive descriptions, photographs of both the basidiocarps and the microscopic structures, and discussions are provided. Sequences of both the nuclear ribosomal internal transcribed spacer region (nrITS) and the nuclear ribosomal large subunit (nrLSU) region of the two new species were obtained and used in the BLASTn searches. Phylogenetic analysis of the nrITS sequences revealed the novelty of the species as well as their placement in the section Coprinopsis.

A checklist and worldwide distribution patterns of macrofungi in Iran
Article
Full-text available
  • Apr 2023

Although West Asia potentially represents one of the diversity hotspots for several groups of fungi, our knowledge of the funga in this region is fragmentary. Here, we provide a list of macrofungal species from Iran and performed a comparative analysis of macrofungal diversity in 12 regions worldwide. The list was compiled from relevant national/international conference letters, GenBank submissions, and published literature in Persian, English, and other languages. In total, 1333 species of macrofungal Asco- and Basidiomycota are listed which were reported from 31 provinces of Iran. We have classified the reported fungi into 12 predefined morphogroups, with most of them being agaricoid species (60%). The Hyrcanian forests that stretch along the Caspian Sea coast in northern Iran are the most species-rich region. Global Biodiversity Information Facility (GBIF) was used to check the number of worldwide occurrences of the reported species which revealed a total of 17 species were exclusively reported from Iran. We suggest that globally rare or low-occurrence species from Iran require global attention and potentially can contribute to the IUCN list of endangered species. Based on comparisons between the macrofungi of Iran and that of various countries, the Iranian species composition is found to be similar to those of the Mediterranean regions.

Coprinopsis (Psathyrellaceae, Agaricales) in the Neotropics: three new species and a new combination
Article
  • Feb 2023
In order to contribute to the knowledge of Coprinopsis in Southern Brazil, specimens were collected in the Atlantic Forest and Pampa Biomes. Morphological studies and phylogenetic analyses (Maximum Likelihood and Bayesian Inference) of the nucITS, nucLSU, TEF1 and β-tubulin were performed to describe new species and their evolutionary relations. Five Coprinopsis species were found. The molecular and morphological data supported the description of three new species and a new combination in the genus. Detailed descriptions, illustrations of their macro- and microscopic characteristics and a key to identify Coprinopsis species in Brazil are provided.

The gilled fungi and boletes of Iran: diversity, systematics, and nrDNA data
Article
Full-text available
  • Jan 2020
A first annotated checklist of agarics and boletes in Iran is presented based on literature and new collections. A total number of 128 new DNA sequences, obtained from the nrDNA ITS region as well as the nrLSU, is provided. Based on vouchered specimens, 19 species are newly recorded from Iran, all provided with nrDNA data from basidiomata. Overall, 585 species (comprising 556 agarics and 29 bolete species) are recorded from Iran, representing 147 genera and 34 families. The order Agaricales encompasses 82% of the species. Twenty-eight species are excluded from the Iranian mycobiota. The Hyrcanian forests harbor 79% of the species, with Mazandaran being the most species-rich province in the country. The three largest genera are Russula, Cortinarius, and Inocybe. We also scrutinized the available DNA sequences of Iranian agarics and boletes deposited in public databases. It is shown that 64 species of agarics and boletes in Iran are from environmental sequences, and nine species have been retrieved as plant endophytes. In total, only 24% of Iranian species are shown to have at least one nrITS sequence in GenBank or UNITE. Our analyses reveal that 42% of records in Iran arise merely from abstracts presented at various conferences, most of which lack sufficient characterization and are suggested to be considered tentatively. General recommendations are given to avoid dissemination of low quality and ambiguous species records. This study fills in some of the gaps in our knowledge of agarics and boletes in Iran and provides a framework for biodiversity and phylogenetic studies.

Article

  • Dec 2018
Twenty-five specimens of coprinoid fungi were collected during an ongoing survey of agaric fungi in Kermanshah Province, western Iran. The specimens were identified based on morphological characteristics and molecular analysis of internal transcribed spacer sequences. Five species of Coprinellus viz C. disseminates, C. flocculosus, C. micaceus, C. radians and C. xanthothrix, three species of Coprinopsis viz C. atramentaria, C. insignis and C. semitalis and two species of Coprinus viz C. pinetorum and C. sterquilinus were identified. Among the species identified in this research, three unreported species from Iran namely C. insignis, C. semitalis and C. pinetorum are reported. Detailed morphological descriptions and illustrations of this three newly-recorded species were provided here and their evolutionary relationships were presented by the constructing of a phylogenetic tree.
