Torrejón, 2009, Mycologia Balcanica 6(3): 113 (more info) Year of publication: 2009 Status of the name: basionym; legitimate MycoBank's opinion: currently used Classification: Fungi, Basidiomycota, Agaricomycotina, Agaricomycetes, Agaricomycetidae, Agaricales, Cortinariaceae, Cortinarius, Cortinarius scobinaceus Obligate synonym(s): none Morphic status: Teleomorph (anamorph connection(s) unknown or not recorded) Taxonomic synonym(s): Ordered by epithet name none Descriptions: Latin diagnosis A typo differt stipite volvato. Typus in loco Altura, Las Boqueras, Hispania, 670 m, 13.XI.2008 leg. et det. M. Torrejón, sub Cistus monspeliensis. Holotypus in SOMF 27 906, isotipus in MTH 998. Original description Etimology: volvatus from the cuplike structure around the base of the stipe. Specimens examined: Altura, Las boqueras, 670 m, UTM 30SYK0705. Scattered on soil, beneath Cistus monspeliensis, 13 Nov 2008 (SOMF 27 906, MTH 998). ? This specimen was collected a little dry and completely mature. Pileus 14–21 mm in diameter, convex, obtusely mammiform, sienna, cinnamon at the mammiform area, hygrophanous, squamulose with small remnant of the general white veil. Lamellae concolorous with pileous, admate with decurrent to emarginate tooth. Stipe 18–36 × 2–3 mm, cylindric, fibrillose, bulbous, truncate with whitish volva. Basidiospores 9.5–12.5 × 4–6 µm, amygdaliform to fusiform, slightly verrucose, brown yellowish. Basidia 26–31 × 9–11µm, 4-spored, claviform. The shape of the cheilocystidia is a transition between hymeniderm and epitelium with claviform to globose apical cells. Pileipellis intricate trichoderm with fibulae and yellow brownish pigments incrusted. ? Cortinarius belleri in Contu & Lavorato (1986) and Lavorato (1991), is similar to our collection, but there is not a description of a volva there. On the basis of these morphological and ecological data (habitat, basidiospore features and cheilocystidia) we consider C. belleri as conspecific with C. scobinacius (Ortega et al. 2006). According to this study, the author’s new variety proposal belongs to C. scobinaceus. Neither Malençon & Bertault (1970) nor Campo (2004) found volva in their collections of C. scobinaceus. ? In the work of Henry & Contu (1985) Cortinarius bulbosovolvatus, which occurs in association with Cistus monspeliensis is described with white volva. Fortunately, we have a collection of this last species from another nature reserve of Castellón, and it allowed us to compare both. The basidiospores of C. bulbosovolvatus are ellipsoid to ovoid or narrowly amygdaloid, shorter and narrower than the species studied. Cortinarius arcanus Moreno et al. (2004) with fusoid and a little narrower spores, shows a brown blackish volva and was collected beneath Pinus pinaster. The rest of the small species of Cortinarius that live in association with Cistus spp. such as C. scobinaceus var. scobinaceus in Malençon & Bertault (1970); C. parvostriatus in Henry & Contu (1985); C. sabulicola in Henry & Contu (1987) and Contu (1991); C. cistophilus in Henry & Contu (1989); C. conico-obtusarum in Ortega & Chevassut (1999); C. castaneus var. monspeliensis and C. impolitus in Contu (2000); C. subcaninus in Torrejón (2002); C. ayanamii in Torrejón (2002, 2003); C. cristallinus in Torrejón (2005); C. contui in Ortega et al. (2007) and C. assiduus var. plesiocistus, C. cystidifer and C. scobinaceus var. cistohelvelloides in Torrejón (2008) have no volva. On the other hand, other species of Cortinarius such as C. pseudoprivignus in Malençon & Bertault (1970); C. bulliardi, C. coeruleopallescens, C. dionysae, C. glaucescens var. maritimus, C. fulmineus, C. illibatus, C. llimonae, C. parvostriatus, C. pseudoprivignus, C. sabulicola, C. variiformis var. crustulinicolor and C. variiformis var. variiformis as Cistus ectomycorrhizal fungi in Comandini et al. (2006) including the species from the work of Lavorato (1991); C. cistoadelphus in Moreno et al. (1997, as Dermocybe cistoadelpha); C. subcotoneus in Bidaud et al. (2007) and C. mahiquesii in Vila et al. (2008) are not Telamonia and all of them are bigger than the specimen studied.
