Abstract
While observing mycelial features of the ectomycorrhizal fungus Rhizopogon roseolus, we noted the formation of hyphal coils in laboratory cultures. The coiled hyphae initially formed at the hyphal tip in the presence or absence of the plant host (Pinus thunbergii), on both rich and poor modified Melin-Norkrans media. Hyphal coils formed from the hyphal tips toward the middle of the hyphae, with rope-like hyphal strands fused as extensive circular coils. Hyphal coils were generally oval and circular. Coils were composed of 1-5 layers of hyphae. Presence of the host had a significant impact on the diameter of the coil loops, which was consistently wider without the host than with the host present on both media. In addition, the terminal part of the mature coils was melanized and separated from the unmelanized coil by a septum. The melanized coils resembled thick condensed hyphae and were detached and scattered throughout the fungal colony. The observation of morphological characteristics suggested that mature coils detached into the mycelia were thromboplerous hyphae. This is the first report on hyphal coil morphogenesis and its potential relationship to the initial development of thromboplerous hyphae.

[PMID: 34349607 PMCID: PMC8328911 DOI: 10.3897/mycokeys.81.65660] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Accepted: 06/16/2021] [Indexed: 11/12/2022] Open
Abstract
Gyroporus species with cyanescent oxidation reactions were investigated, based on morphology and phylogenetic analysis of DNA sequences from the nuclear ribosomal large subunit (nrLSU), the nuclear ribosomal internal transcribed spacer (ITS) and the mitochondrial adenosine triphosphate ATP synthase subunit 6 (atp6). Three species, including two new species, namely G.alpinus and G.flavocyanescens and one previously-described species, namely G.brunneofloccosus, are revealed from China. Collections formerly reported from China as “G.cyanescens” are either G.alpinus or G.flavocyanescens. The new species are documented and illustrated in detail, while the concept of G.brunneofloccosus is refined with additional recently-collected materials. Additionally, the cyanescent species G.pseudomicrosporus, previously described from China, is shown to be a member of the genus Gyrodon, based on re-examination of the type specimen. A key to the cyanescent Gyroporus species from China is provided.

Abstract
Neoboletus infuscatus (Boletaceae, Boletales) is described as a new species from Yinggeling of Hainan Tropical Rainforest National Park, southern China. It is morphologically characterized by a large basidioma with a nearly glabrous, brownish yellow, yellowish brown to pale brown pileus, pores orangish red when young, yellowish brown to brown when old, context and hymenophore staining blue when injured, a yellow stipe with red punctuations, surfaces of the pileus and the stipe usually covered with a thin layer of white pruina when young. Phylogenetic analyses of DNA sequences from part of the 28S gene, the nuclear rDNA internal transcribed spacer (ITS) region, and part of the translation elongation factor 1-α gene (TEF1) also confirm that N. infuscatus forms an independent lineage within Neoboletus. Detailed morphological description, color photos of fresh basidiomata and line-drawings of microstructures are provided.

Abstract
A new species of Parvixerocomus, P. matheranensis belonging to Boletoideae of Boletaceae is described and illustrated from tropical region of Maharashtra, India. P. matheranensis is morphologically distinguished by small basidiomes having ruby red pileus with concolorous stipe, yellow hymenophore that stains blue to blackish blue on bruising, elongate ellipsoid to cylindrical basidiospores with inconspicuous suprahilar depression, ventricose to clavate cheilocystidia, ventricose to lageniform pleurocystidia. Further, extensive phylogenetic analyses based on five gene markers (nrITS, nrLSU, rpb1, rpb2, tef1-α) confirmed that P. matheranensis is distinct from its closest taxa P. aokii and P. pseudoaokii and also from other members of Boletoideae.

Abstract
Species of the genus Retiboletus in China were investigated based on morphology and phylogenetic analysis of DNA sequences from the nuclear ribosomal large subunit (nrLSU) and the translation elongation factor 1-α gene (TEF1-α). Nine species were recovered from China, including two new and seven known species. The new species, namely Retiboletusater and R.sinogriseus, from southwestern and northeastern China respectively, are documented and illustrated in this paper. Retiboletusater is morphologically characterized by its black to grayish black pileus, white to grayish hymenophore, black to blackish stipe and white to grayish white context. Retiboletussinogriseus is morphologically characterized by its brown to grayish-brown pileus, yellow to grayish-yellow hymenophore, pale yellow to brownish stipe and yellow to brownish-yellow context. Descriptions and line drawings of these two novel species and their comparisons with allied taxa are presented.
