Abstract

&lt;htm&gt;&lt;i&gt;Hohenbuehelia &lt;/i&gt;(Pleurotaceae) in western Paraná, Brazil &lt;/htm&gt;

Records of lignicolous agaricoid fungi (Agaricales, Basidiomycota) from Mexico

“…Remarks.-The Mexican specimen fit very well with the macro and micromorphological features described for Hohenbuehelia portegna: brown pileus with tomentose to hirsute surface, margin slightly striate, similar size of the hairs in the pileipellis, and hyphae of the pileipellis with brown encrusted pigment (Putzke & Cavalcanti,1995;Silva-Filho & Cortez, 2017). The basidiospores in the Mexican specimen are slightly smaller than those cited by Putzke & Cavalcanti (1995), who found 9.5-12 × 4.5-6.5 µm, and Silva-Filho & Cortez (2017), who reported 7-11.5 × 3-5 µm; however, Singer & Digilio (1951) cited basidiospores most similar in size than our specimens, with 8.3-9.8 (-11.8) µm long [as Hohenbuehelia atrocoerulea f. portegna (Speg.)…”

“…Singer]. Another difference is the narrower cheilocystidia compared with those cited by Silva-Filho & Cortez (2017), who pointed out cheilocystidia of 4-13 µm wide.…”

Additions to Hohenbuehelia (Basidiomycota, Pleurotaceae): two new species and notes on H. tristis from northern Thailand

“…The basidiomata range from white, yellowish-white, yellow-brown, to pinkish-orange, and are spathulate to flabelliform. Hohenbuehelia angustata , originally described from Brazil, differs from H. flabelliformis by its smaller, smooth, greyish-yellow basidiomata, with stipe 4.5 mm long, smaller basidiospores (3.5–5 × 2.5–3.5 µm), smaller cheilocystidia, and the presence of pileocystidia ( Silva-Filho and Cortez 2017 ). H. horrida and H. odorata differ from H. flabelliformis by smaller basidiospores (5.2–7.6 × 4.8–6.4 µm), lack of cheilocystidia, and presence of pileoleptocystidia ( Bijeesh et al 2019 ).…”

“…However, those species have significant morphological differences. Hohenbuehelia angustata differs from H. lageniformis by having a smooth pileus surface, serrate margin, smaller basidiospores (3.5–5 × 2.5–3.5 µm), cutis pileipellis ( Silva-Filho and Cortez 2017 ). Hohenbuehelia bonii differs by having a smooth pileus surface and larger pleurocystidia (56–103 × 11–19 µm) ( Ainsworth et al 2016 ).…”

“…Currently, 126 taxon names are listed under Hohenbuehelia in Index Fungorum ( http://www.indexfungorum.org/ ), for 50 accepted species ( He et al 2019 ; Wijayawardene et al 2022 ). The typical characteristics of this genus are pleurotoid, gelatinous basidiomata, white basidiospores with a germ pore, lecythiform cheilocystidia (if present) and thick-walled metuloid pleurocystidia ( Stevenson 1964 ; Thorn and Barron 1986 ; Corner 1994 ; Silva-Filho and Cortez 2017 ; Holec and Zehnálek 2020 ).
