status

The studied specimen is characterized by the presence of one kind of thick-walled fusiform cystidia, thickwalled hyphae, and ornamented, broadly ellipsoid basidiospores measuring 5.5–6.5 × 4.5–5 µm ( Fig. 10 View FIGURE 9–12 ). Although thickened hyphae have been reported for H. cremicolor by Paulus et al. (2007) and Tellería et al. (2010), thick-walled cystidia is not typical for the species. Thick-walled hyphae are not described in H. punctulatum (Cooke) J. Erikss. nor H. albostramineum (Bres.) Hallenb. Hypochnicium cremicolor was previously reported from Uruguay ( Martínez & Nakasone 2011) in South America. It is typically distributed in Europe (Bernicchia & Gorjón 2010) but it has also been reported from the Canary Islands ( Tellería et al. 2010) and Korea ( Jung 1996) Hypochnicium cremicolor is morphologically and phylogenetically closely related to Hypochnicium cystidiatum Boidin & Gilles and H. aoteraoe B.C. Paulus, H. Nilsson & Hallenb. , which have two kinds of cystidia ( Paulus et al. 2007). Hypochnicium guineensis Tellería, M. Dueñas, Melo & M.P. Martín has more globose basidiospores and encrusted, thick-walled cystidia ( Tellería et al. 2010). Hypochnicium patagonicum Gorjón & Hallenb. has thick-walled cystidia often with secondary septa and larger basidiospores ( Gorjón & Hallenberg 2012).
