March 2006 Catathelasma 7 5 LYCOPERDON RIMULATUM, A NEW SLOVAK GASTEROMYCETE 1 MIKAEL JEPPSON Key words: Záhorská/Borská nížina, Lycoperdon decipiens The sandy district Záhorská (Borská) nížina (Záhorie lowland), between the river Morava and the mountains of Malé Karpaty, just north of Bratislava, is an area from which several species of gasteromycetes have been reported (cfr. Kotlaba 1955, Pilát 1958). It is an agricultural area with cultivated fields as well as pine, oak and robinia forests on sandy soil along with some spots of inland sand dunes and sand fields with a more or less pannonic vegetation. With the aim of checking the present status of gasteromycetes in the area, field studies were conducted by the author in the autumns of 2000, 2004 and 2005. Several interesting species were recorded, one of which, Scleroderma septentrionale, could be reported new to Slovakia (Jeppson & Piątek, in print). However several of the sites mentioned by the earlier Czech and Slovak gasteromycetologists indicate a considerable and continuing change in land use (eg. ceased grazing) which appears to be detrimental to the growth of several rare species of gasteromycetes, today appearing on the redlists of many European countries. During the visits to Záhorie a number of different habitats have been scrutinized: abandoned fields, pastures, mowed sandy grasslands, open sand dunes, sandy pine and oak forests, sandy paths and road tracks, road verges, military training fields etc. These sites offer exposed habitats with a patchy vegetation of low herbs, mosses and lichens mixed with open sandy spots suitable for the growth of xerothermophilous and psammophilous species of gasteromycetes. This paper is a report of a rare puff ball, Lycoperdon rimulatum, found in a sandy heathland habitat with Corynephorus canescens, on a military training field south east of the little village Mikulášov in 2005.

Young fruitbodies greyish- pinkish with a slight orange tinge, with an exoperidium constructed of adpressed, more or less asteriform floccules. Mature fruitbodies are almost smooth or show filamentous remnants of the floccules. Endo- peridium greyish brown, paler towards base, at the apex distinctly dark March 2006 Catathelasma 7 7 violet due to escaping spores. Spore print is very dark brown with violaceous tinges. The capillitium is elastic, brown, rarely ramified, 4-6 µm in diametre, with thin to medium thick walls (< 1 µm) without pores and septa. The spores are sphaerical, 5-6.5 µm in diametre (measured without ornamentation), strongly warted (D in the terminology of Demoulin, 1971) and covered with an epispore. Some spores are provided with long pedicells (up to 20 µm) and abundant broken pedicells are mixed with the spores in a mount. The large and strongly warted spores provided with pedicells are diagnostic in combination with the weakly developed exoperidial ornamentation. A related species, Lycoperdon decipiens, is also known from dry and open situations. It is often depressed globose in shape, has a prominent pseudorhiza and has similar colour of the mature spore print but it usually produces a well developed exoperidium constructed of whitish spines. Furthermore, its spores are smaller (4.5-5 µm) and although broken pedicells are always abundant in mounts of L. decipiens, the spores are never pedicellate as in L. rimulatum. The Slovak collection from Mikulášov perfectly matches descriptions of L. rimulatum given by Coker & Couch (1928), Lloyd (1905) and Smith (1951). Bates (2004) states the spores of collections from Arizona of L. rimulatum to be 6.4-8.0 µm but his measurements are given including the spore wall ornamentation. He also mentioned numerous pits in the capillitial wall, a character which could not be verified in the Slovak collection. In Demoulin´s experience (Demoulin, 1971), pits in the capillitial walls may occur in the odd specimen, but is considered pathological. THE SLOVAK SITE The Slovak site is situated in the sandy south western part of Slovakia, south east of the village Mikulášov, in a military training area with open sand dunes and sand fields dominated by Corynephorus vegetation and partly covered with a light forest of Pinus silvestris and Quercus sp. The sand is mainly acidic but in places where the upper layers of sand have been disturbed (eg. along roads) the soil reaction appears to be more alcaline, with tufts of the calcicolous grass Koeleria glauca. The forest is rich in mykorrhizal fungi and is a popular place for mushroom pickers in the autumn. During two visits (17. 10. 2004 and 3. 10. 2005) several interesting gasteroid fungi were met with, viz. Geastrum minimum, Tulostoma brumale, Astraeus hygrometricus, Lycoperdon ericaeum, L. norvegicum, L. marginatum and Scleroderma citrinum. 8 Catathelasma 7 March 2006 In 2005 Lycoperdon rimulatum was found among Corynephorus canescens in a glade in the pine-oak-forest, some 100 metres SW of the main road from Lakšárska Nová Ves to Plavecký Mikuláš. A total of 6 fruitbodies were found in an area of less than 10 square metres. The earth star Geastrum rufescens and the puff ball Lycoperdon marginatum were recorded in close vicinity of L. rimulatum. DISTRIBUTION AND NATURE CONSERVATION ASPECTS Lycoperdon rimulatum was described by Peck in 1899. According to Demoulin (1971) and Bates (2004) it has a wide distribution in central and eastern parts of North America from Florida in the south to Ontario in the north. In North America it has been recorded in open, sandy areas but also in forests. As for Arizona, Bates (2004) mentions grassy open areas or amid leaf or needle debris under Abies spp., Quercus spp. and Pinus ponderosa. The first European record of this species was a collection sent to C. G. Lloyd (Ohio, USA) in the early 20th century from T. de Aranzadi of Barcelona. Lloyd kept no further records of this collection (herb. Lloyd at BPI. C.21999 p.p., according to Demoulin, 1971) and its origin remains obscure. Hollós (1904) mentioned and illustrated this species in his monograph but brought no European records of it. Šmarda (in Pilát, 1958) treated it as a variety of L.
