An Indian collection (RET 717-9) is grouped phylogenetically with Chinese material of
<taxonomicName lsidName="A. virgineoides" pageId="0" pageNumber="73" rank="species" species="virgineoides">A. virgineoides</taxonomicName>
(HKAS 79691, GenBank nrLSU: KJ466495 and HKAS 77278, GenBank nrLSU: KC429043), with pairwise genetic divergence between their nrLSU sequences = 0.35% (might be intragenomic heterogeneity present amongst collections as the sequence was not clean). It is worth mentioning that there is no genetic distance between rpb2 sequences derived from the Chinese (HKAS 79691, GenBank rpb2: KJ466663) and Indian (RET 717-9) collections. The evidence suggests that the two collections could be conspecific and exhibiting a minor intra-specific variability. In addition, the sample size is also small. For these reasons, we do not feel justified in erecting a new species or subspecies. Interestingly, another Chinese collection (HKAS 18394), labelled as

), is also grouped with the Indian collection, but the sequence derived from this collection is divergent from the two previously cited collections (Fig. 1). However, the habit and size of the basidiomata and basidiospores of the Indian collections match well with those characters in the descriptions of
