Mycostilla vermiformis

Mycostilla vermiformis (Berk. & Broome) Spirin & Malysheva, in Spirin et al., Antonie van Leeuwenhoek 112(5): 760 (2019)

Basidiocarps gelatinous, first appearing as conical or needle-like outgrowths 0.050.2 mm long, partly fusing, semitranslucent, greyish or with faint pinkish or violaceous tints, later coalescent and producing reticulate compound basidiocarps 0.51 cm in diam. Hyphae clamped; subicular hyphae with distinct walls, 23.5 μm in diam., subhymenial hyphae thin-walled, 12 μm in diam. Basidiospores (3.3–) 3.75.9 (–6.2) 9 (2.9–) 3.05.2 (–5.9) μm (n = 160/6), L = 4.285.22, W = 3.724.70, Q = 1.101.15. Basidia (6.8–) 7.08.7 (–8.8) 9 (5.8–) 6.17.6 (–7.8) μm (n = 20/2), sterigmata only rarely bifurcate, 316 9 12 μm, enucleate stalk 416 9 1.72.8 μm. Tramal cystidia tubular, apically obtuse, 52140 9 818 μm (n = 20/2); gloeocystidia tubular to somewhat fusiform, running parallel to tramal cystidia, 1694 9 49 μm (n = 20/2). Hyphidia occasionally branched, 13 μm in diam.

Index Fungorum number: IF826892

Figure 1Phylogenetic relationships of lineages within the Auriculariales: a the best tree from the ML analysis of the nrLSU dataset. ML BS and Bayesian posterior probability (pp) values for internal nodes are given above the branches (BS/pp); b the best tree from the ML analyses of the nrITS dataset. Voucher numbers are given for newly sequenced specimens and accession numbers for additional sequences retrieved from GenBank. Scale bar shows expected changes per site
