Echinoporia hydnophorus

Synonyms:

=Polyporus hydnophorus Berk. & Br. 1873, Journ. Linn. Soc. 14: 54.

Type: Ceylon, in Herb. Berkley No. 367, Herbarium K.

Macromorphology:

Resupinate to pileate, ochraceous (herbarium specimens). Pileus, if present ca. 0.5 cm wide, up to 2 cm long, up to 4 mm thick, context white to ochraceous. Pores up to 3 mm long, positive geotropical growing, pore walls up to ca. 100 µm thick, 3-5 pores per mm. Surface of the pileus and upside directed, horizontal and resupinate parts of the basidiocarp are covered by bristle-like outgrowings, which are 1-2 mm long. These outgrowings grow negativly geotropical and produce at their tops arthroconidia.

Micromorphology:

Spores:

5-5.5 x 4.5-5 µm, subglobos to globos, thin-walled, smooth, hyaline, inamyloid.

Basidia:

10-16 x 5-7 µm, young slightly suburniform with one mediane constriction, mature clavate to barrel shaped with one basal clamp each.

Cystidia:

1. Lagenocystidia, basal ventricose and apical tapering a little with crystalline incrustation. Walls of the lagenocystidia up to 1 µm thick. They arise from the hymenium with one basal clamp each.

2. Clavate hyphal endings with a strong thickened wall (up to 2 µm), apical up to 12 µm in diameter. They arise from the subhymenium with one basal clamp each.

Clamps:

All primary septa with one clamp each.

Conidia:

Arthroconidia, 5-9 x 5-6 µm, globos to long ellipsoid, smooth, hyaline, at one end with a hook-like formed rest of a clamp. They are produced by terminal dissection of the endhyphae of the bristle-like outgrowings (see above).

Hyphae:

Hyphal system dimitic. Skelettal hyphae 2.5-7 µm in diameter, thick-walled (up to 2.5 µm). Generative hyphae 2-3 µm in diameter, thin-walled to slightly thick-walled (< 0.5 µm). In the subiculum and in the bristle-like outgrowings of the fruit bodies surface, skelettal hyphae and generatic hyphae are located next to each other.
