New species of Clavulina from Guyana

  title={New species of Clavulina from Guyana},
  author={Jason R. Thacker and Terry W. Henkel},
  pages={650 - 657}
Two new species of Clavulina are described from rainforests dominated by ectomycorrhizal Dicymbe spp. (Caesalpiniaceae) in the Pakaraima Mountains of Guyana. Clavulina nigricans, sp. nov. is unique for Clavulina in having 4–6 spores per basidium. Clavulina craterelloides, sp. nov. has an infundibuliform basidiome, previously unknown in the otherwise coralloid genus Clavulina. Macromorphological, micromorphological and habitat data are provided for each taxon, as well as justification for their… 
New Clavulina species from the Pakaraima Mountains of Guyana
Five new species of Clavulina are described from the Pakaraima Mountains of Guyana, occurring in rain forests dominated by the ectomycorrhizal tree Dicymbe corymbosa (Caesalpiniaceae).
Clavulina incrustata, a New Species from Pernambuco, Brazil
Abstract Clavulina incrustata is described from Atlantic Forest of Pernambuco, Northeast Brazil, and is characterized by the branched basidiomata, hymenium pale vinaceous fading to very pale
New species and distribution records of Clavulina (Cantharellales, Basidiomycota) from the Guiana Shield
Two new species of Clavulina Schroet and C. sprucei represent the first reports of the species since 1853 as well as a range extension of nearly 1500 km, while sequence data from basidiomata as to ECM roots suggest that this taxon consists of a cryptic species complex.
New species of Clavulina (Cantharellales, Basidiomycota) with resupinate and effused basidiomata from the Guiana Shield
Micromorphological features and DNA sequence data from the second largest subunit of DNA-dependant RNA polymerase II (rpb2) and internal transcribed spacer (ITS) and large subunit (28S) of the ribosomal repeat justify placement of these new species in Clavulina.
Two new species of Clavulina (Cantharellales) from southwestern China based on morphological and molecular evidence
Two new species of Clavulina (Clavulinaceae, Cantharellales, Basidiomycota) from southwestern China are substantiated based on morphological evidence and molecular phylogenetic analyses based on sequences of the second largest subunit of DNA-dependent RNA polymerase II (RPB2) and the large sub unit of nuclear ribosomal RNA gene (LSU).
Two new species of Clavulina and the first record of Clavulina reae from temperate Abies religiosa forests in central Mexico
This work describes two new species, C. mahiscolorata and C. parvispora, from temperate forests of central Mexico, and presents a geographical range redistribution of C. reae, which displays great macromorphological variation regarding basidiome branching rank, colors, and tip shape.
Clavulina amazonensis, an Amazonian fungus discovered in the Atlantic Forest
Clavulina amazonensis, an Amazonian fungus discovered in the Atlantic Forest, is characterized by branched basidiomes with, hymenium, small subglobose basidiospores, frequency of three sterigmata per basidia and context bearing orange-brown hyphae.
Afrocantharellus gen. stat. nov. is part of a rich diversity of African Cantharellaceae
A new genus in the Cantharellaceae, Afrocantharellus, is recognized based on results from phylogenetic analyses of rDNA LSU and concatenated LSU/5.8-ITS2/ATP6 data. It was previously recognized as a
Ectomycorrhizal fungal diversity and community structure on three co-occurring leguminous canopy tree species in a Neotropical rainforest.
Ectomycorrhizal species in Agaricales, Atheliales and Polyporales may represent previously unrecognized tropical-endemic ECM lineages and spatial factors are more important than hosts in structuring the ECM fungal community in this ecosystem.
Pakaraimaea dipterocarpacea is ectomycorrhizal, indicating an ancient Gondwanaland origin for the ectomycorrhizal habit in Dipterocarpaceae.

This paper provides the first documented evidence of ECM in a neotropical genus of Dipterocarpaceae and indicates that ECMs possibly evolved in Gondwana in ancestors of Diptersons before the separation of South America from Africa by the Atlantic, c.


Pseudotulostoma , a remarkable new volvate genus in the Elaphomycetaceae from Guyana
Pseudotulostoma volvata gen. sp. nov. is described from the south-central Pakaraima Mountains of Guyana. Pseudotulostoma volvata is associated with ectomycorrhizal Dicymbe corymbosa trees
Notes on clavarioid fungi. XX: New taxa and distributional records in Clavulina and Ramaria
Clavaria americana is placed in synonymy under C globospora, and Ramaria spinulosa is recorded from the southern Appalachian Mountains.
Russulaceae of the Pakaraima Mountains of Guyana. I. New species of pleurotoid Lactarius
Morphological and habitat descriptions, illustrations and taxonomic discussions are presented for two newly described species of pleurotoid Lactarius, L. brunellus and L. multiceps, from the
Ectomycorrhizal fungi and their leguminous hosts in the Pakaraima Mountains of Guyana
The spatial restriction of EM fungal basidiomes indicated that discrete groves of EM trees harbour an important component of regional macromycete diversity.
Systematics of pleurotoid Russulaceae from Guyana and Japan, with notes on their ectomycorrhizal status.
Three species of pleurotoid, putatively lig- nicolous basidiomycetes previously described in the genus Lactarius sect Panuoidei were redescribed from fresh material collected in Guyana and Japan, confirming that these fungi are ectomycorrhizal and that their fruiting habit on organic deposits and well rotted wood at elevated positions is not due to sap- rotrophy, as previously assumed.

Dominance of primary rain forests by the ectomycorrhizal, leguminous canopy tree Dicymbe corymbosa (Caesalpiniaceae) was investigated in the Pakaraima Mountains of western Guyana, indicating persistent monodominance.
Inheritance of DNA methylation in Coprinus cinereus
The inheritance of 5-methylcytosine residues at a centromere-linked locus in the basidiomycete Coprinus cinereus was examined and it was found that the higher levels of methylation at this locus were transmitted through meiosis, regardless of the level ofmethylation of the homologous chromosome.
