臘腸形炭角菌具有小型子座、皺紋及細網格狀裂紋在子座表面、小尺寸子囊孢子。這些特徵顯示其與角狀炭角菌(X. corniformis) 及其類似種有相似的形態。根據數段核酸序列所進行的親緣關係分析,臘腸形炭角菌與白鱗炭角菌(X. curta) 聚成一群;白鱗炭角菌亦與角狀炭角菌有相似的形態。臘腸形炭角菌之全模式(holotype) 標本過於成熟,我們因此指定一份標本為其附加模式(epitype)。
Xylaria botuliformis is characterized mainly by small stromata with a wrinkled and finely reticulately cracked surface and minute ascospores. These features suggest the placement of X. botuliformis in the X. corniformis group. Phylogenetic ana-lyses based on sequences from several DNA loci clustered X. botuliformis together with X. curta, a member of the X. corniformis group, and thus agree with the morphological features. The holotype of X. botuliformis is overmature, and we thus designate an epitype for it.
