Facesoffungi number: FoF 07602

Ascomycota, genera incertae sedis


Saprobic on petiole of Calamus walkeri (Arecaceae) and on leaves of Panicum sulcatum (Poaceae) (Yanna et al. 1998). Sexual morph: undetermined. Asexual morph: Conidiomata dark brown, pycnidial, solitary or gregarious, superficial, globose, unilocular, setose. Ostiole absent, dehiscence by breakdown of apical wall. Conidiomatal setae brown, concentrated on the upper surface, thick-walled, branched, aseptate, with stellate apex. Conidiomatal wall composed of thick-walled, dark brown to hyaline cells of textura intricata to textura angularis. Conidiophores arising from inner wall of conidioma, reduced to conidiogenous cells. Conidiogenous cells hyaline, enteroblastic, phialidic, doliiform to ampulliform, determinate, unbranched, smooth-walled. Conidia hyaline, oval to ellipsoidal, 0–1-septate, smooth-walled, eguttulate (Morgan-Jones et al. 1972d, Yanna et al. 1998).


Type species: Staurophoma panici Höhn., Denkschr. Kaiserl. Akad. Wiss., Math.-Naturwiss. Kl. 83: 34 (extr.) (1907)


Notes: Chaetasbolisia, Dasysticta and Staurophoma possess pycnidial, globose, unilocular, setose conidiomata and phialidic, doliiform to ampulliform conidiogenous cells and hyaline conidia (Sutton 1980). Staurophoma differs from Chaetasbolisia and Dasysticta by its short, stellate conidiomatal setae (17 × 4.5 μm). Dasysticta was separated from Chaetasbolisia by its much longer conidiomatal setae (up to 650 μm long) and cylindrical conidia often with a large central guttule. Staurophoma was re-described by Sutton (1980) and illustrated by Morgan-Jones et al. (1972d). The second species S. calami Yanna, K.D. Hyde & Goh collected on Calamus walkeri from Hong Kong was included by Yanna et al. (1998). This species is distinguished from S. panici by its larger conidiomata and 1-septate conidia. The genus has not been studied with molecular data. Fresh collections of type species are needed to place it in a natural group.


Distribution: Brazil, China (Sutton 1980, Yanna et al. 1998).
