A New Species

Fuscoporia caymanensis sp. nov. is described from tropical America. It is characterized by perennial, extensive, resupinate to indistinctly effused-reflexed basidiomata; a very thin to almost absent subiculum; multi-layered tubes with a black line between each layer; a dimitic hyphal system with skeletal hyphae occasionally septate; absence of mycelial setae and cystidioles; abundant hymenial setae, 40–55 × 5–7 μm; urniform basidia, and cylindrical basidiospores 4.5–5 × 2–2.4 µm. It was found growing on fallen rotten angiosperm trunks in tropical America. Phylogenetically, it is related to Fuscoporia viticola and F. palomari, but the latter two species have longer basidiospores (7–9 × 1.5–2 µm in F. viticola and 8–10 × 2.7–3.5 μm in F. palomari), and occur in temperate regions.

A New Species

Phylloporia moricola is described as a new species based on collections from Sichuan Province, China. All studied basidiocarps grow on trunks of Morus sp. This new species is supported by morphological features and phylogenetic analyses of DNA sequences inferred from a dataset of nuc 28S rDNA. P. moricola is characterized by having effused-reflexed to pileate basidiocarps, pores 7–9 per mm, duplex context with a black line when young, dimitic hyphal system, and brownish, slightly thick-walled basidiospores generally measuring 3.4–4 × 2.7–3.2 μm. Phylloporia moricola is phylogenetically most closely related to Phylloporia mori, that also occurs on Morus sp., but that species differs from P. moricola in having hymenial setae and larger basidiospores (4–4.8 × 3.1–3.8 μm).

Gammaropsis elvirae sp. nov. is described and illustrated here, as a new species of the family Photidae Boeck, 1871, occurring on sites widely distributed in the soft-sediment habitats from the Yucatan shelf, southern Gulf of Mexico. This new species differs from all other congeners by a unique set of characteristics: lateral cephalic lobes rounded; outer lobes of lower lip with one cone on each lobe; gnathopod 1 propodus longer than carpus; gnathopod 2 propodus enlarged with small convoluted processes on posterior margin and palmar angle undefined; gnathopod 2 dactylus short, less than one half in length of propodus; dense setation on basis, carpus, and propodus of gnathopod 2; epimeral plates 1–3 rounded; inner ramus of uropods 1–3 longer than outer ramus; and telson emarginated. Ecological comments on spatial distribution and associated environmental variables are included, as well an identification key to the genus in tropical America.

A New Species

A new species of Fistulina, F. tasmanica sp. nov., is described and illustrated from Tasmania in Australia. Fistulina tasmanica is distinguished by its pileate and fleshy basidiomata with rose pore surface, fibrous context, separated tubes with small pores (6–7 per mm), a monomitic hyphal system with only clamped generative hyphae, subellipsoid to ellipsoid basidiospores (5.4–6 × 3.4–4 μm) which are negative in Melzer’s reagent and cotton blue. Phylogenetic analyses inferred from the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU) sequences also confirmed that F. tasmanica is a new member within Fistulina.

A new species, Stropharia acanthostipitata, is here described from the Dominican Republic and French Guiana based on morphological and molecular ITS/LSU analyses. It is distinguished by a dry, smooth and hygrophanous pileus with minute and fugacious velar remnants at the pileus margin, exannulate stipe, brown lamellae, presence of chrysocystidia on both edge and face of lamellae, and the occurrence of acanthocytes all over the stipe surface.

Four new species of Bjerkandera, viz. B. ecuadorensis, B. fulgida, B. minispora, and B. resupinataspp. nov., are described from tropical America and Asia. B. ecuadorensis is characterised by dark grey to black pore surface, a monomitic hyphal system, hyaline to yellowish-brown generative hyphae, and ellipsoid basidiospores measuring 3.9–4.5 × 2.7–3 μm. B. fulgida is distinguished from the other species in the genus by clay buff to pale brown and shiny pore surface. B. minispora is characterised by white tomentose pore mouth and small basidiospores measuring 3.1–4.2 × 2–2.8 μm. B. resupinata is characterised by resupinate basidiomata, pinkish buff to pale brownish pore surface, and ellipsoid to broadly ellipsoid basidiospores measuring 4.5–6 × 3.2–4.1 µm. All these new species grow on angiosperm trunks or rotten wood, and cause a white rot. The closely related taxa to four new species are discussed. An identification key to the ten accepted species of Bjerkandera is provided, and a phylogeny comprising all known Bjerkandera species is provided.
