Ethiopian forests are rich in valuable types of non-wood forest products, including mushrooms. However, despite their nutritional, economic, and ecological importance, wild edible mushrooms have been given little attention and are rarely documented in Ethiopia. In this study, we assessed mushroom production levels in natural and plantation forests and the influence of climate and environmental variables on mushroom production. Sporocarps were sampled weekly from July to August 2019 at a set of permanent plots (100 m) in both forest systems. We analyzed 63 plots to quantify sporocarp species' richness and fresh weight as well as to elucidate the degree of influence of forest types and site conditions, including soil and climate. Morphological analyses were used to identify fungi. In total, we recorded 64 wild edible fungal species belonging to 31 genera and 21 families from the plots established in the natural and plantation forests. A significantly greater total number of edible fungi were collected from natural forests (n = 40 species) than from plantations. Saprotrophs (92.19%) were the dominant guild whereas ectomycorrhizal fungi represented only 6.25% of species. Ecologically and economically important fungal species such as , , , , and were collected. The sporocarp yield obtained from plantation forests (2097.57 kg ha yr) was significantly greater than that obtained from natural forests (731.18 kg ha yr). The fungal community composition based on sporocarp production was mainly correlated with the organic matter, available phosphorus, and total nitrogen content of the soil, and with the daily minimum temperature during collection. Accordingly, improving edible species' richness and sporocarp production by maintaining ecosystem integrity represents a way of adding economic value to forests and maintaining biological diversity, while providing wood and non-wood forest products; we propose that this approach is imperative for managing Ethiopian forests.
埃塞俄比亚的森林富含包括蘑菇在内的多种珍贵的非木材林产品。然而,尽管野生可食用蘑菇具有营养、经济和生态重要性,但在埃塞俄比亚却很少受到关注,也鲜有记录。在本研究中,我们评估了天然林和人工林中蘑菇的产量水平,以及气候和环境变量对蘑菇产量的影响。2019年7月至8月期间,每周在两个森林系统的一组固定样地(100米)采集子实体。我们分析了63个样地,以量化子实体物种的丰富度和鲜重,并阐明森林类型和立地条件(包括土壤和气候)的影响程度。通过形态学分析来鉴定真菌。我们从天然林和人工林中设立的样地总共记录了64种野生可食用真菌物种,分属于31个属和21个科。从天然林中采集到的可食用真菌总数(40种)显著多于人工林。腐生菌(92.19%)是主要的类群,而外生菌根真菌仅占物种的6.25%。采集到了一些具有生态和经济重要性的真菌物种,如 、 、 、 和 。人工林的子实体产量(2097.57千克/公顷·年)显著高于天然林(731.18千克/公顷·年)。基于子实体产量的真菌群落组成主要与土壤中的有机质、有效磷和总氮含量以及采集期间的日最低温度相关。因此,通过维持生态系统完整性来提高可食用物种的丰富度和子实体产量,是一种在提供木材和非木材林产品的同时,为森林增加经济价值并维持生物多样性的方式;我们认为这种方法对于埃塞俄比亚森林的管理至关重要。
