New host records of Ganoderma in northern Thailand and determination of nutritional contents of selected Ganoderma species

Abstract

Ganoderma P. Karst is a group of wood-degrading mushrooms, and some are medicinal mushrooms that are ecologically and economically important. Ganoderma has distinctive non-laccate and laccate basidiocarps and double-wall basidiospores. This fungus is known to cause infections in hardwood hosts in tropical and temperate regions. This study reports non-laccate (Ganoderma gibbosum) and laccate (G. tropicum) species on a new host species, Anthocephalus chinensis, from Chiang Rai Province in Thailand. Comprehensive details of the two Ganoderma reported herein were proposed, described, and illustrated based on macro- and micro-morphology. The phylogenetic position was evaluated using the ITS sequence. The phylogenetic tree is provided to show the placement of taxa. Medicinal G. tropicum was selected to investigate the nutritional content. A high value was observed on energy (187.43) and dried matter content (75.92 ± 1.96 g/100g), followed by crude fiber, carbohydrates, protein, and moisture contents 51.53 ± 2.65 g/100g, 49.86 ± 1.98 g/100g, 14.64 ± 1.24 g/100g, 7.24 ± 0.40 g/100g, 1.86 ± 0.23 g/100g, and crude fat of 1.23 ± 0.19 g/100g, respectively.
