Lindgomyces pseudomadisonensis

Lindgomyces pseudomadisonensis Tak. Takah. & Kaz. Tanaka

 

Index Fungorum number: IF817598; Facesoffungi number: FoF02434

Holotype: HHUF 30513

Etymology: Referring to its resemblance to Lindgomyces madisonensis.

 

Saprobic on submerged wood. Sexual morph: Ascomata 190–240 μm high, 230–360 μm diam., globose to subglobose, black, scattered to grouped, immersed to erumpent. Ostiolar neck 90–100 μm long, 40–55 μm wide, papillate, central. Peridium 50–55 μm thick, composed of an inner layer of polygonal to subglobose, hyaline to pale brown cells and an outer layer of brown cells. Pseudoparaphyses cellular, numerous, 1.5–2.5 μm wide, anastomosed, branched. Asci 92.5–130 – 13.5–17.5 μm ( = 108.3 9 15.6 μm, n = 8), fissitunicate, clavate, rounded at the apex, with an apical chamber, with eight overlapping bi-seriate ascospores. Ascospores 28–41(–45.5) – (5.5–)7–10 μm ( = 36.3 9 7.9 μm, n = 63), l/w 3.7–6.1 ( = 4.6, n = 63), fusiform with acute ends, straight or slightly curved, with the primary septum almost supramedian (0.40–)0.42–0.51 μm ( = 0.47, n = 62), slightly constricted at the primary septum, with a broad upper cell, hyaline, smooth, becoming 3-septate and pale brown with age, surrounded by an entire gelatinous sheath ca. 2 μm wide. Asexual morph: Undetermined. (Description from Hirayama et al. 2010)

 

Material examined: JAPAN, Aomori, Nishimeya, Seisyu trail, Ooshirosawa River, on submerged dead twigs of woody plant, 28 August 2010, K. Tanaka et al., KT 2742 (HHUF 30513, holotype); ex-type living culture, MAFF 245610.

 

Freshwater distribution: Japan (Hyde et al. 2016)

 

Notes: Lindgomyces pseudomadisonensis is morphologically similar to L. madisonensis and phylogeny also support a close association between them. However, the former has shorter ascospores ( = 39 ± 2 9 7 ± 1 μm). In addition, the ascospores of L. pseudomadisonensis have an entire gelatinous sheath. The identities of ITS sequences between L. pseudomadisonensis and L. madisonensis are rather low [GenBank KT207819; Identities = 541/564 (95.9 %), Gaps = 9/564 (1.5 %)]. (Notes from Hirayama et al. 2010)
