GYROMITRA FR. SENSU LATO (DISCINACEAE, PEZIZALES) IN MONTENEGRO Branislav Perić * & Olgica Perić ** * University of Montenegro, Biotechnical Faculty, Mycological center 81000 Podgorica, Mihaila Lalića 1, Montenegro branislav@mycolmonten.org **81000 Podgorica, Đulje Jovanova 16 Abstract 11 taxa of the genus Gyromytra Fr. sensu lato recorded in Montenegro are presented. These are G. esculenta (Pers.) Fr., G. gigas (Krombh.) Cooke, G. geogenia (Rahm) Harmaja, G. infula (Schaeff.) Quél., G. martinii Donadini & Astier, G. megalospora Donadini & Riousset), G. neuwirthi Velen., (= G. esculenta var. fragilis Marchand ex Réaudin, 2008), Gyromitra fastigiata (Krombh.) Rehm, G. parma (J. Breitenb. & Maas Geest.) Kotl. & Pouzar, G. perlata (Fr.) Harmaja and G. tasmanica Berk. & Cooke. The southernmost point of G. geogenia range, for now, was found in this region. G. neuwirthii, G. fastigiata and G. tasmanica are rare entities, new for Montenegro. The latter occures in Southern Hemisphere, previously was reported only in Spain in Northern Hemisphere. Key words: Discinaceae, Gyromitra, gigas, geogenia, infula, martinii, megalospora, neuwirthi, fastigiata, parma, tasmanica, Montenegro Introduction T he genus Gyromitra Fr. s.l. (Pezizales), at the present time, increasingly come to our attention. Probable reasons for that are, not only the attractiveness of these specific discomycetes and ambience in which they develop, but also a complete nice atmosphere during early spring trips. Most species mainly inhabit high mountain areas and should be sought in the time of melting snow or shortly thereafter. Otherwise, working with them requires great patience due to delayed maturation of ascomata. After collection it is necessary to be kept in the refrigerator, maintaining an adequate level of humidity, pursuant to natural conditions, in order to complete maturation.

Branislav Perić & Olgica Perić Material & Method The material was collected in the Mediterranean, sub-mediterranean and continental region of Montenegro. Investigation was conducted on fresh material while verification was done, on several occasions, on herbarium specimens. Macroscopic descriptions of species and photo illustrations were done in situ with Fg20 reflex Nikon camera and digital cameras Nikon 100 and C5D. Microscopic analysis was performed using the optical microscope (Leica DMLS). Microscopic observations were made on sections, prepared by hand with razors then mounted in the water, Congo Red, Melzer s reagent (to monitor amyloid reaction of ascus), Cotton blue and lacto phenol (to monitor ascospore ornamentation). Micro illustrations were made with the digital camera (DC 300). Drawings of microelements were done using pen and ink and as well as micro illustrations were processed with Adobe Photoshop CS4. 30 ascospores were measured from different apothecia. The material is stored in the herbarium of Mycological Centre, Biotechnical Faculty in Podgorica. Systematic position 120 The family Discinaceae Benedix emend. N.S. Weber, Trappe & O Donnell is characterized by the following features: Macroscopic features epigeous or hypogeous ascomata generally of large stature, sessile or stipitate, cupulate, cerebriformis or more or less correctly or incorrectly tuberiformis, hymenium in shades of whitish, through ocher-yellow to a more or less dark brown and dark, almost black and brown; outward surface smooth or downy, whitish or coloured like hymenium; stalk if present, less/more cylindrical, with ribes, full or hollow with chamber, whitish or brownish surface with a pinkish or purple reflex; flesh broadly at the intersection. Microscopic features asci operculate eightspored, uniseriate, J-, cylindrical, base type pleurorinque; paraphyses at top clavate, with brownish intercellular pigment; ascospores ellipsoidal, fusiform or spherical with characteristic extensions (apicule) at the poles, hyaline, smooth or ornamented with cyanophilous episporium in maturity, with four nuclei, containing one to three large oil drops; excipulum composed of intertwined cells in the form of textura intricata rarely of textura angularis which is in the ectal excipulum. In regards to mutual generic boundary of particularly complex entity of the family Discina Neogyromitra Maublancomyces Paradiscina Gyromitra Pseudorhizina, to date, acceptance has not been established. The discussion about relationship between Discina and Gyromitra is characterized by mutually opposing opinions. They can be divided into three groups. The first group of authors (Dennis, 1978; Breitenbach & Kränzlin, 1984; O Donnell et al., 1997; Vizzini, 2003 and Medardi, 2007) believe that Discina and Gyromitra are two autonomous genera. Another group (Eckblad, 1968; Donadini, 1984, 1987; Luchini, 1986) has the opinion that they are subgeneric entities of genus Discina. The point of view of the third group (Harmaja, 1969a, 1969b, 1973, 1976a, 1976b; Kotlaba & Pouzar, 1974; Pfister,

Gyromitra Fr. sensu lato (Discinaceae, Pezizales) in Montenegro 1980; Abbott & Currah, 1997; Eriksson et al., 2004; Medel & Marmolejo, 2005; Lumbsch & Hundorf, 2007; Van Vooren & Moreau, 2009a) is that they are subgeneric entities of genus Gyromitra. For complete information of this complex issue we refer to: Benedix (1969, 1972) McKnight (1969), Harmaja [1969a, 1974 (1973)], Donadini (1987), Abbott & Currah (1997). In this paper, we rely on the infra-generic systematic proposed by Abbott & Currah (1997), followed by Van Vooren & Moreau (2009) and supplemented by Van Vooren (2009). Also, we follow the position of O Donnell et al. (1997) in terms of belonging of this genus to the family Discinaceae not Abbott & Currah (l.c.), which classify it in Helvellaceae. Subgenus Gyromitra, section Gyromitra Type: G. esculenta The results of research Basic taxonomic data: all species of subgenus Gyromitra, unlike other subgenera, have stipitate ascomata. In addition they are characterized by irregularly shaped cap with cerebriformis surface or more or less grouped irregular lobe. Ascospores are ellipsoidal or fusiform, smooth (observed by optical microscope) and generally, with two polar drops. Gyromitra esculenta (Pers.) Fr., 1849, Summa veg.

It occurs in autumn, unlike others from the same genus. Subgenus Discina (Fr.) Harmaja section Discina: Typ : G. perlata (Fr.) Harmaja Basic taxonomic data: the species are recognized as sessile or subsessile, apothecia fleshy. Only recently Abbott & Currah (l.c.) noted anatomical and microscopic affinities of these species with the species of subgenus Gyromitra. Ascospores usually are ellipsoidal, sometimes fusiform, with one or three drops, smooth or ornamented, always with apicule at the poles, which can be reduced as a blunt extension.

Branislav Perić & Olgica Perić Note: It develops on dry beech stumps and trunks. A similarity with G. parma, which also develops in hardwoods, has led to the hypothesis that it may be a unique species (Baute, 2006; Van Vooren & Moreau 2009b). According to current insights, it looks that in Montenegro is not so rare. Discussion 132 11 taxa from the genus Gyromytra Fr. sensu lato presented in the paper were collected in Montenegro and studied during over the past ten years. During the preparation of this paper, we revised some of the earlier records and now we give updates. The material previously reported as Gyromitra esculenta is shown to be G. gigas due to as immature ascocarp as our incorrect determination. That was at the beginning of our work when we had less experience. As regards current taxonomic knowledge of the genus, the material previously reported as G. esculenta according to Van Vooren & Moreau (2006) now is recognized as G. neuwirthii. Due to limited space here, detailed macro and micro descriptions that we have done for all the species, are not included. This will be done in a forthcoming paper. We provide the Figure 1. with microphotos of ascospores of all taxa and Figure 2. with photos of all ascomata. At first, the material was collected during the usual spring trips to the mountain sites of Montenegro, and only recently, we have taken systematic visiting certain mountain areas searching for species from the genus Gyromitra. We have visited localities in Continental mountain region Hum Orahovski, National Park Durmitor, National Park Biogradska gora, Hridsko lake above Plav, Jezerine on Mt. Bjelasica, and in Massif Komovi the northern slopes (Trešnjevik and Štavna) and southern slopes Planinica, Bijela voda and Kurlaj. Mediterranean forest in site above Budva was viseted only once, after that it was burned. Sub Mediterranean sites in and near Podgorica (Park Forest: Ljubović, Gorica, Zlatica; forest stands toward Agricultural combines, Tuzi and Golubovci) were also visited. Seasonalan visits to Mt. Durmitor, Mt. Bjelasica and recently Hrid above Plav throught years did not yield the expected results. It appears that the species associated to the genus are not widely distributed in our mountains as it is the case with the Central European and North European regions. The majority of species was collected in the conifer stands of Pinus halepensis, P. heldreichii, Abies alba and Picea abies. Several were found in mixed stands and only two species were found exclusively on the beech. It is interesting to note that G. gigas, which is usually found in coniferous forest, we found in the clearing of beech forest. Regarding to substrate, species occur on rich humus soil, usually near trees, stumps or lodged trunks, on sandy soil and some of them are lignicolous. G. neuwirthii, G. fastigiata and G. tasmanica are rare entities, new for Montenegro. The latter is a mycological element of the Southern Hemisphere. It was observed on the Northern part of our Planet only in Spain and Montenegro. Our records of G. megalospora and G. martinii are notable because these species were recorded only in France. For G. geogenia we found the southernmost point of its range. According to our current insights, G. perlata and G. martinii are widely distributed

Gyromitra Fr. sensu lato (Discinaceae, Pezizales) in Montenegro species in the area of Montenegro. That could be said as for G. gigas. We assume that G. megalospora occurs in our coastal forests of pine trees, although we have not visited these sites during the spring. Special attention was devoted to visiting the vicinity of the Black Lake in Mt. Durmitor searching for Gyromitra macknightii Harmaja, where is its locus classicus. All our collections from that localities were determinated as D. perlata. Abbott & Currah (1997) reduced G. macknightii to synonym of G. perlata. Therefore the localities on Mt. Durmitor merit further monitoring. The mutual generic boundary of particular complex entity of the family Discinaceae, Discina Neogyromitra Maublancomyces Paradiscina Gyromitra Pseudorhizina, has been intractable problem for decades. We expect that it should be resolved soon by biomolecular research. Therefore, our collections of dried specimens will be proccesed by this analyzes. Literature cited Abbott S. P. & R. S.
