Türkiye Mikobiyotası İçin Yeni Bir Mycena Kaydı
Abstract: The mycenoid species, Mycena pterigena (Fr.) P. Kumm. (Mycenaceae) is given as new record from Turkey. A brief
description of the species and photographs related to its macro and micromorphologies are provided.
Key words: New record, Mycena, Trabzon, Turkey

1. Introduction
Mycena (Pers.) Roussel is a large genus of the family
Mycenaceae Underw., with about five hundred known
species worldwide (Kirk et al., 2008). The members of the
genus are generally small mushrooms rarely exceeding a
few centimeters in diameter and are characterised by very
fragile and thin, membranous, conical to campanulate
pileus; adnate to arcuate or decurrent lamellae; 1-4-spored
basidia; intricate cystidia; white spore print; and smooth,
hyaline spores. Almost all the members of the genus are
saprotrophic and play a vital role in litter decomposition
especially in forests and woodlands. Species of the genus
have cosmopolitan distribution, and are usually
determined on the debris of conifers, other woody plants
and rarely on or among the debris of grasses, mosses,
ferns (Pegler, 1986; Singer, 1986).
On 8 October 2016 some small pinkish mycena samples
were collected from Uzungöl Nature Park within the
Çaykara district of Trabzon province and identified as
Mycena pterigena (Fr.) P. Kumm. Tracing the current
checklists (Sesli and Denchev, 2014; Solak et al., 2015)
and the latest macrofungal studies (Akata et al., 2016;
Denğiz and Demirel, 2016; Kaya et al., 2016; Öztürk et
al., 2016; Sesli et al., 2016; Taşkın et al., 2016; Uzun and
Acar, 2016; Kaya et al., 2017; Uzun and Kaya, 2017;
Uzun et al., 2017a; 2017b, 2017c), it was founded that the
taxon has not been recorded from Turkey before.
The work aims to contribute to the mycobiota of Turkey.
2. Materials and Method
Macrofungi specimens were collected from Uzungöl
Nature Park within the Çaykara district of Trabzon
province during field trips in 2016 Morphological and
ecological characteristics of the samples were recorded
and they were photographed in their natural habitats. Then
the specimens were transferred to the fungarium.
Necessary microscopic investigations were carried out
within the fungarium. Photographs related to
micromorphology were also obtained during these
investigations. The samples were identified with the help
of Redhead (1984) and Miller (2004).
The specimens are kept at Karamanoğlu Mehmetbey
University, Kamil Özdağ Science Faculty, Department of
Biology.
3. Results
Basidiomycota R.T. Moore
Agaricales Underw.
Mycenaceae Roze
Mycena pterigena (Fr.) P. Kumm.
Synonym: Agaricus pterigenus Fr., Agaricus pterigenus
Fr. var. pterigenus, Agaricus rubeolarius With., Mycena
pterigena (Fr.) P. Kumm. var. pterigena.
Macroscopic features: Pileus 2-4 mm across, cylindrical
when young then conical to campanulate, slighthly
sulcate, translucent-striate, glabrescent to somewhat
pruinose, pale salmon to pale pink, somewhat pale
brownish at the centre. Flesh membranous, odor mild.
Lamellae broadly adnate, decurrent, whitish to pale rose.
Stem 10-35  0.2-0.3 mm, cylindrical, threadlike,
concolorous with the cap or paler when young, then
becomes transparent and grayish brown when mature,
thicker at the base or somewhat bulbous (Fig. 1).

Microscopic features: Basidia 20-25  8-10 µm, broadly
clavate, 4-spored (Fig. 2a). Cheilocystidia abundant, 19-24
 11-15 µm, clavate to almost spherical, covered apically
with fairly numerous, simple, rarely furcate, cylindrical
projections up to 11 µm long (Fig. 2b). Pileipellar hypha
also covered with warts or short cylindrical excrescences
(Fig. 2c). Spores 7-10  3-5 µm, narrowly to broadly
elliptic, hyaline, smooth (Fig. 2d).
Specimen examined: Trabzon, Çaykara, Uzungöl Nature
Park, roadside on dead Pteridium sp. stem, 40°36′N-
40°19′E, 1470 m, 08.10.2016, Yuzun 5275.

4. Discussions
Current checklists on Turkish macromycota (Sesli and
Denchev, 2014; Solak et al., 2015) indicate that 62
Mycena species have so far been recorded from Turkey.
With this addition of Mycena, current species number of
the genus Mycena increased to 63.
Like Mycena pterigena, M. lohwagii also determined from
fern associated habitats, but it has a greyish pileus when
young, has a larger fruit body, shorter projections on its
cheilocystidia, larger spores and colonizes rhizomes
(Miller, 2004).
