Paradiacheopsis longipes Hooff & Nann.-Bremek., Proc. K. Ned. Akad. Wet. View in CoL 99(1-2): 51 (1996) ( FIGURE 4 View FIGURE 4 )
Saprobic on dried twigs of an unidentified woody plant. Sexual morph: Not observed. Asexual morph: Sporangia stipitate, gregarious, globose and brown to dark brown, 380–450 μm high (x = 415 μm, n = 20). Stalk clustered, cylindrical, brown to dark brown, 1,150 –1,470 μm high (x = 1,339 μm, n = 20), upper stalk 60–145 μm (x = 103 μm, n = 20), and becoming wider at the base reaching to 315 μm. Columella thick and irregular, giving rise to primary branches of the capillitium along its entire length. Capillitium formed by brown threads frequently branching and intricately anastomosing, reaching the surface as long, straight, finely pointed horizontal free ends. Spores globose with verruculose protuberances, 5‒7.5 μm diam. (x = 6 μm, n = 30), pale brown.
Culture characteristics: Single-spore isolation was repeated three times on culture media (PDA and WA), and no germinated spore was observed.
Material examined: China, Sichuan Province, Chengdu City, Qionglai County, Nanmuxi, 103°7’16” E, 30°18’ N, elevation 775 m, on dried twigs of an unidentified woody plant, 24 August 2021, Y.P. Chen and Y.B Guo, NMX07 (HUEST 01.0275).
Notes: In the Index Fungorum (https://indexfungorum.org/Names/Names.asp, accessed January 10, 2025, Paradiacheopsis includes eight accepted species, all of which were described before the 21st century, with no molecular data available for any of their type materials. For our newly collected specimen, although we attempted to extract DNA directly from the fruiting bodies on natural substrates three times, all attempts were unsuccessful. Through a literature review, we compiled the spore characteristics of these eight species ( TABLE 3). HUEST 01.0275 has pale brown spores, which are similar to those of Paradiacheopsis longipe , as well as in conidial size dimension (5‒7.5 μm vs. 7–8 µm diam.) ( Hooff & Nannenga-Bremekamp 1996). Therefore, we identified the newly collected specimen (HUEST 01.0275), as Paradiacheopsis longipes . The species was first reported by Ukkola et al. (2001) from Hunan Province, China, but no morphological data were provided. This study reidentifies the species in Sichuan Province and offers detailed characterization and visualization.
