Galiicola

Galiicola Tibpromma, Camporesi & K.D. Hyde, in Ariyawansa et al., Fungal Diversity: 10.1007/s13225-015-0346-5, [79] (2015)

Index Fungorum number: IF 551383; Facesofungi number: FoF 00923

Etymology: refers to the host genus from which the taxon was collected.

Saprobic on Galium. Sexual morph: Ascomata solitary, semi-immersed or slightly erumpent though the host surface, appearing as black dots on the host surface globose to subglobose, with a small central ostiole. Ostiole short, shiny, apapillate. Peridium composed of 3–5 layers of thin-walled, yellow to orange brown, flattened cells. Hamathecium comprising numerous 1.7–2.3 μm wide, filamentous, branched, anastomosing, septate pseudoparaphyses. Asci 8-spored, bitunicate, cylindricclavate, with short pedicel, apex rounded an ocular chamber. Ascospores overlapping 1−3 seriate, initially hyaline, becoming orange brown at maturity, elongate fusiform, with 4–5 transverse septate, some with 1–2 vertical septa, constricted at central septum, cell above central septum slightly swollen. Asexual morph: Undetermined.

Type species: Galiicola pseudophaeosphaeria Tibpromma, Camporesi & K.D. Hyde

Notes: The genus Galliicola belongs in the family Phaeosphaeriaceae where it is basal to Xenophoma. The genus is unique in Phaeosphaeriaceae in having a peridium of 3–5 layers of thin-walled, yellow to orange-brown, flattened cells and orange-brown ascospores (Ariyawansa et al. 2015)
