Observations on the boletes of the Cooloola Sand-mass, Queensland and notes on their distribution in Australia: Part 3. Lamellate taxa

Abstract

The lamellate boletes found in the Cooloola Sand-mass, Queensland are described and discussed in the light of earlier Australian records of paxilloid fungi. Nine species of Paxillus are discussed, two in Tapinella, which is maintained as a separate entity, and 11 are assigned to Phylloporus. Of the last, eight are new records to Australia and two are new species. Three appendices cover various aspects of studies on Australian boletes which have come to light since the publication of this series, including notes on the host-range of the parasitic hyphomycete Sepedonium.

Strobilomyces echinocephalus sp. nov. (Boletales) from south-western China, and a key to the genus Strobilomyces worldwide

“…Taking into account that a comprehensive molecular approach to Strobilomyces worldwide has not yet been attempted, the following dichotomous key is based on both morphological (see also Horak 1980) and molecular data when available. Species recorded by Watling and Gregory (1986) and successfully quoted by Watling and Li (1999) from Australia but not formally described are also integrated for completeness. Spores dimensions are given including ornamentation.…”

“…cf. mollis Corner (see Watling and Gregory 1986;Watling and Li 1999) 32a: Hymenophore whitish at first then greyish and further darkening, owing to the ripening of the spores…33 33a: Pileus small, 3-4.5 cm broad, blackish, subtomentose and finely areolate, whitish in the cracks, tubes adnate, stipe with a thickened annular zone at apex, entirely smooth and minutely fibrillose, basal mycelium brownish, context not turning reddish and possibly unchangeable on exposure, spores 8.5-10 × 8-9 μm, occurring in south-western China…S. zangii Gelardi 33b: Pileus larger…34 34a: Pileus 7.7-9.2 cm broad, with large, areolate, flattened blackish patches, 5-18 mm wide, tubes sinuate, stipe reticulate above the floccose annulus, smooth below, hymenophore and context discoloration unknown, spores 7.4-8.9 × 6.7-8.1 μm, occurring in southern China…S.…”

“… S. fasciculatus Cooke → Type immature/sterile, likely a Boletus/Xerocomus according to the very short protologue.  S. indica Lloyd → No data, but according to Corner (1972), Horak (1980) and Singer (1945), this latter quoted by Watling and Gregory (1986), it might be conspecific with the Australian S. velutipes.  S. kalimpongensis Bose → No data, type material not available (Polyporus s.l.?).…”

“…The re-examination of the type material preserved in the Herbarium of Cryptogams of Kunming Institute of Botany (KUN-HKAS 3224) by the Japanese authors definitely confirmed its incorrect classification and, accordingly, H. nigricans is here formally transferred to Strobilomyces with a new name (in honor of Prof. Zang), since the epithet nigricans was already used by Berkeley (1852) to describe a different taxon belonging to the same genus and occurring in India (type collection), Cambodia (Perreau-Bertrand 1961;Horak 1980) and possibly Australia (Watling and Gregory 1986). S. nigricans reported by Boedijn (1960) from Java and successfully by Corner (1972) …”

Cultivation of Phlebopus portentosus in southern China

“…To increase production of P. portentosus, research on its cultivation has been carried out since 2003 at the Yunnan Institute for Tropical Crop Research, China. The biotrophic status of P. portentosus is still not clearly known, although some mycologists have proposed that it could be an ecto-or a facultative mycorrhizal fungus (Watling and Gregory 1988;Sanmee et al 2010;Lumyong et al 2007). Based on our field observations on the relationship of the fungus with the range of hosts listed above, we also considered that P. portentosus could be an ecto-or a facultative mycorrhizal fungus.…”
