Ceriporia amazonica Soares, Sotão & Ryvarden

sp. nov.

Ceriporia amazonica Soares, Sotão & Ryvarden   , sp. nov. ( Fig. 1 View FIGURE 1 : A−C)

Mycobank no.: MB 808528  

This species differs from the other Ceriporia species   by its combination of salmon basidioma, large angular pores (1 –3 per mm) and small ellipsoid spores.

Holotype: — BRAZIL. Amapá: Amapá National Forest , December 2009, leg. H. Sotão 2009-278 ( MG 203521 View Materials , isotype in O).  

Etymology: —the name refers to the region where the specimen was collected.

Basidioma annual, resupinate; pore surface salmon (45) to peach (46) colored when fresh and snuff brown (17) when dry, fading to yellowish brown, pores shallow, angular to honeycomb in a reticulate pattern, 1−3 per mm, margin narrow, concolorous with pore surface, tube layer up to 0.5 mm deep, drying brittle, subiculum thin, up to 300 μm thick, soft, white. Hyphal system monomitic, generative hyphae simple-septate, thin-walled, 2−5 μm in diam. Cystidia or other sterile hymenial elements absent. Basidia not seen. Basidiospores ellipsoid, 3 × 2 μm, negative in Melzer’s reagent.

Distribution: —Known only from the type locality in state of Amapá, Brazil.

Ecology: —On a dead, fallen hardwood.

Taxonomic remarks:— The salmon-coloured basidioma makes this a conspicuous species when observed in the field. Ceriporia spissa (Schwein. ex Fr.) Rajchenb.   has a similar color, but it has pores ranging from 7−9 per mm and allantoid basidiospores ( Aime et al. 2007). In addition, the basidiospores of C. amazonica   are among the smallest in the genus and should aid in the identification of the species. Ceriporia incrustata M. Mata & Ryvarden   and C. microspora I. Lindblad & Ryvarden   have basidiospores of similar size (3−3.5 × 1.8−2 μm and 3−3.5 × 1.5−2 μm, respectively), but smaller pores (6−8 per mm in both species). Besides, the former has ochraceous basidiomata and the latter, white basidiomata ( Lindblad & Ryvarden 1999, Mata & Ryvarden 2010).
